    Qualcomm's secrets disappear
posted 10:03am EST Mon Sep 18 2000

Irwin Jacobs, the CEO of Qualcomm, has reported that his laptop was stolen from a ballroom where he was addressing the Society of American Business Editors and Writers. According to reports, the laptop was left on the podium for about 15-20 minutes and was taken when Irwin went to talk to a small group.

The laptop is believed to contain valuable company secrets and proprietary information that could be valuable to foreign governments. According to Qualcomm, the laptop is password-protected and its data was previously backed up on a computer at Qualcomm's headquarters.

As of this writing the laptop has not been recovered and Jacobs is considering contacting the FBI.


While Jacobs did say that his laptop is password-protected, I haven't been able to find any information that talks about what kind of password protection his laptop actually had. For example, if all he had was basic BIOS-level protection, someone could easily take his hard drive and plug it into another IBM laptop to access the data.

I don't understand why companies like Qualcomm wouldn't use the highest level of protection possible to ensure the safety of the data that its executives carry around. In this case, the person carrying the data is the CEO so you can imagine that his laptop would be a definite target. I've walked through hotel conference rooms in the past and seen laptops just sitting around. This could have been a completely random snagging, too.

Perhaps it's time to rethink the way we currently offer security on laptops. For example, if instead of typing in a quick password to protect his laptop Irwin actually had removed his hard drive and took it with him off the podium, this problem would never have occurred. Then again, we don't know for sure that Irwin even password-protected his laptop. After all, he probably felt pretty safe there talking to a small group.

CEO's and rules.... (11:17am EST Mon Sep 18 2000)
It's been my experience that the upper management of any large corporation feel that they are immune to processes and procedures that have been put in place. A low-level grunt such as myself would have security galore on his laptop, but CEO's are generally lazy enough that they would not want to be bothered with the hassle of actually having to key more than one password.

BTW - I've seen it mentioned that this is an IBM laptop. Hopefully for Qualcomm, a hard drive level password was set. There is a way to lock the hard drive behind a password so that no matter where the drive goes, the password goes with it. According to IBM, this password is secure enough that even they would not know how to get around it if you have a memory lapse. Not sure if this is true or not, but we all know that there is no such thing as absolute security on a computer. - by Porsche

There is a way around hard drive level passwords on IBM laptops, but it isn't easy, and it isn't general knowledge. - by Just a Guy
Just curious (12:46pm EST Mon Sep 18 2000)
Generally speaking, how would one get around a hard drive level password? Could you break that down for us, Just a Guy. I'm simply curious, as we have a few IBM laptops at work. Thanks. - by 0311Grunt
HDD security (2:07pm EST Mon Sep 18 2000)
Well... if a it was stolen to get his files then trust me it was "opened" already with any security level.
Fastest and easiest that comes up in my mind would be "DATA RECOVERY LAB" :) ... just open up HDD and u have all the data :).

Hard drive level security (4:15pm EST Mon Sep 18 2000)
As far as I know, there is no such thing. Unless anyone publishes a link to an article describing this, then I will not believe it. What if an IBM hard drive was to be used on a Toshiba machine? The Toshiba BIOS would not recognize a proprietary "hard drive password." I think that's just made up. BIOS password - yes, Windows 2000 password - yes, security for a naked hard drive - not that I've ever heard. - by RobGeek

IBM Passwords (11:39am EST Tue Sep 19 2000)
I have an IBM Thinkpad 600X, and I do have some sort of Hardrive password, when I turn on my computer and enter the password it first shows my computer unlocking and then it shows my hardrive unlocking... obviously this might just be flashy pictures with nothing really happening, but my hardrive doesnt work in any of my other laptops when i have this enabled. - by Kevin
Hard drive passwords (7:37pm EST Tue Sep 19 2000)
Interesting. Thanks for the info. So, it appears that IBM has some special mechanism in their hard drives to effectively leave them in an on or off state based on whether they are locked or unlocked by an IBM notebook BIOS. Well, I still don't have a link to the security... In fact, I checked and I couldn't find anything about this. Is it some kind of big secret? Searching for "security" on all of IBMs websites reveals 1 page. Yikes. - by ROB'S
Removing IBM HDD Passwords (6:31pm EST Wed Sep 20 2000)
IBM ThinkPads can have up to three levels of security passwords. (1) Power-On Password - This password is stored in the system bios, and can be cleared by disconnecting all batteries, or by shorting a jumper. (2) Hard Drive Password - This password is stored on the hard drive itself. Therefore, moving a drive that is protected in this manner to another computer will not allow you to access the drive (unless you know the password). This can be defeated by shorting a jumper on the hard drive itself, but on most ThinkPad models, this will require that the drive housing be partially disassembled. (This will likely damage the drive housing on 760 class machines. 770 class drive housings should be able to be reassembled without too much difficulty. 600 class machines do not have any drive housings. I don't know about other models). (3) Supervisor Password - This is a combination of Power-On and Hard Drive password. This requires that these two passwords be identical. If a hard drive is removed from a machine with a supervisor password, the hard drive cannot be accessed (as with a hard drive password), and the ThinkPad will not boot - even with another hard drive. These can be bypassed by clearing the hard drive and power-on passwords seperately. - by Just a Guy
Conspiracy Theory II... (5:29pm EST Fri Sep 22 2000)
If this was a corporate or government theft, expect the thief to have access to a clean room where they can transfer the drive platters.

600x Thinkpad (1:33pm EST Mon Feb 19 2001)
I've read that Nortek can remove passwords on Thinkpads, so how come IBM claim that the serial board needs replacing at $950.

Are they robbers, their laptops are'nt the cheapest the least you would expect is that they would be more responsive to peoples problems.

And JUST A GUY is talking nonsense if he knew of a way to clear a supervisor password he would give it up freely.

Good Luck to all, eventually the way will become clear, we all may just have to wait a while.

Has anyone here tried Nortek (10:12am EST Fri Apr 20 2001)
Has anybody tried Nortek and were they successful?

I've had a price from Nortek for $195, supervisor and hardrive password removal.

If I bought a new hardrive this would still not clear the supervisor password and may even write it to the hardrive and encrypt the new drive also.

Message for Profix keep up the good work, do you have a list of things you have tried, if so please email to me at

ThinkPad Password Solutions (9:29am EST Fri May 11 2001)
An unknown ThinkPad Power On password can usually be removed by the user (servicing a system yourself may void any or all remaining warranties). ThinkPad Power On password removal information can usually be found in a system’s Hardware Maintenance Manual. The following web site contains links to IBM web pages where specific ThinkPad system manuals can be downloaded.

If the ThinkPad continues to prompt the user for a password after Power On password removal is attempted, the ThinkPad most likely has a Supervisor password set. There is no way a user can remove or bypass an unknown ThinkPad Supervisor password. Under normal circumstances, the Supervisor password automatically activates the Hard Disk password access to the HDD and stored drive data is impossible (from any system) if the password is unknown.

Proprietary software and hardware was developed that is capable of removing unknown ThinkPad Supervisor and notebook Hard Disk passwords with the option of full HDD data recovery, without replacing any hardware components. Visit the web site below for full password removal details.

Anyone with a non-commercial solution, someone out there must know how to do it, not that I am against commercial solutions, I realise the importance of R&D - I work for an R&D company.
I had visited the nortek website already, as I suspect most of the people who have posted here have. It is simply not cost effective (especially as I am based in the UK) to do this - I am not interested in the data, I just want to be able to use the hard drive.
Maybe nortek would consider lowering the price for unlock-only (no data recovery). This may make the option more attractive for many people who have posted here and elsewhere. If they want the business. - by pdpdjh

hdd password (9:49am EST Sat May 19 2001)
I have a Travelstar 4gig HDD with a password. I bought it used. Been looking everywhere for a solution(I know about Nortek, but $100US is WAY too much for this drive). I tried plugging in just the logic board to see if I get an error and it bings me to setup screen, but nothing happens(just hands at the Thinkpad logo, no password icon comes up). I beleive it(password) is on the HDD platter and not the logic board. Oh well, I guess I'll keep lookin.

supervisor password (11:42am EST Wed May 23 2001)
Contrary to IBM lies, the supervisor password can be reset by removng the power supply, battery and then removing the cmos battery and waiting 20 minutes or so. On the IBM Thinkpad A20M, the cmos battery is conveniently located beside the mini pci modem/network card. Gently unplug the battery and voila! Sorry IBM, you can't have the $750 to replace the system board!
Now if someone could post the HDD password unlock solution, we would all be back in business instead of dealing with slimy, money-grabbing so called customer service reps/companies. - by Trallane
IBM ThinkPad Passwords (6:02pm EST Fri May 25 2001)
The supervisor password cannot be removed on most ThinkPads by unplugging the CMOS battery because it is stored in an EEPROM. It can be got around quite easily if you have the gear but there is no quick or dirty fix. The BIOS of a ThinkPad will read the checksum of the EEPROM as well as looking for a password so replacing the chip won't help either. I haven't spent much time figuring out the Harddisk password system as these can be replaced anyway, I did swop controller boards on two identical drives however and the passworded drive remained so. This means the password is somehow stored on the platter and causes the drive to mis-report itsself to the BIOS. Connecting a passworded drive to a desktop machine simply resulted in the password protected drive not being reconized, although the IBM Tool DiskManager could see the drive and also the password. This means it won't allow you low level format it. - by Dan

HDD password (7:08am EST Wed May 30 2001)
I have had some success in defeating the password. I removed the logic board from the HDD, connected(just the logic board) to my Thinkpad and powered up. After a few minutes, the password screen came up. 2 attempts at entering a password and it halted(hand icon). Normally it's supposed to be 3 attempts before it halts. I then re-assembled the HDD and this time it didn't ask for a password when I booted with a win98 startup disk. When I ran fdisk, it asks if I want a FAT32 drive, then quits saying it cant access the drive.I downloaded a utility from IBM that performs diagnostics and low level format. The low level format ran for about 20 hours, then failed at about 85%. If Nortek and that UK company can do it, so can we!! Someone out there MUST know. - by TRoN

More on Passwords (5:21pm EST Sun Jun 03 2001)
In response to Chuck I was talking about EEPROM programmers. As mentioned before the password is stored in an EEPROM, in the ThinkPads case a serial EEPROM designed for small sensitive data such as passwords in mobile phones and notebooks etc. My company once purchased 30 x 760ED notebooks from a corporate who then refused to give out the passwords. Although we were willing to junk the drives we would have lost out big time on the machines so we simply brought in an non passworded 760ED and cloned the EEPROM(Probably what the other companies do)
Looking at the tech PDF's of TravelStar drives they support a command to disable password protection. At the moment we are working on an assembly programm to low level interface the drives and hopefully disable the password to allow a low level format. I suspect removing the password and keeping the data intact would prove tricky but we really only want to be able to use the drives. - by Dan

Well, for all you people out there who want their 760E, 760XL, 760ED (do not ask about any other types) thinkpads working then would some one please tell me where I can post a "dirty fix" that ACTUALLY WORKS!!!not here...I need a less conspicuous arena as IBM may SUE me ( ex-engineer )and I definitely do not want that! If you do not mind virtually stripping your laptop and trying a bypass operation (hey, if its locked then you wont mind) then I have a solution that has worked eliminating the supervisor password...afraid you must change your hard drive first...the thinkpad original will never relinquish its password this way and will remain stone cold dead still...give it up...suggest putting a low capacity hard drive in temporarily.

380z (8:09pm EST Wed Jul 25 2001)
My test on a 380z type 2635 using magnets. I removed the system board memory and cmos bat shorted the cmos bat terminals then ran a rather strong magnet over the system board. I then re assembled the 380z i it reports error 161 and 163 then asks for the password. any password will do and it then attempts to boot but now it will only boot off of a system program disk any other disk and it go's directly to a halt message. the system program disk boots but when i try to program the bios it tells me that the power management is disabled and will not continue. - by 380z
380z continued (8:21pm EST Wed Jul 25 2001)
I was referring to the Administrator password. shorting the cmos and password terminals alone did nothing. also this dose not address the hd password. I have attempted to use the hd in a apple powerbook but partitioning the drive always fails with an unknown error.

Having a password that can not be removed or at such a ridiculous price is idiotic thing for IBM to do. any common thief probably would not ask more than 50 bucks and i dought they would even turn it on. the chances that someone's ***CHILD*** would set the password when they found daddies laptop is much more likely and just puts a sour note in the consumers mind. and any serious thief with purpose would have ways of extracting the data. the hardware in the system except the mb and hd are still viable parts for resale even for the educated thief and probably more profitable and less obvious.. any way I think of it its pad for the consumer and meaningless to the thief..... - by 380z

760ED Supervisor Password (12:41pm EST Thu Aug 02 2001)
Does anyone know where the Password Files reside?
I purchased a 760ED 6 months ago (2nd User) and wanted to upgrade the Bios however as the supervisor password is set, i cannot complete the task. I have stripped the machine down as the casing was broken and have all the parts required to refurbish it (ordered from IBM NPL Part Sales UK)
Reading the datasheets for the relevant I.C.s the security space is either the Dallas DS17485 RTC. (4Kb ram) or the Intel E28F004 Flash memory. Or is there something I've missed?
U41 looks suspicious (serial EEPROM??)
it bears an IBM part No.
Once I know where the passwords are I will use a device reader to read the contents, then usecmospwd (downloadable from numerous sources)to convert to ASCII or keyboard scan codes.

hdd password detection (3:22pm EST Thu Aug 02 2001)
I just found out my used ThinkPad 770 has a supervisor password set - found this out when I went to put a larger hard drive into the machine. Since I bought the unit used, I do't know the system password (working on getting that, but doubtful). Since setting the system password sets the hard drive password, is there any way to detect the hdd password? This may give me the system password! - by Xopher
hey hello Hi !!! i got the logic to remove Supervisor Password (8:03am EST Sun Aug 05 2001)
just email me at to remove ur supervisor password for IBM ThinkPad 390/E/X ...... - by Shafiq
has anyone tried this: (4:39am EST Mon Aug 06 2001)
it just came to my mind that PROBABLY and JUST probably, the HD password is stored in the HDD partition, if it is, then putting this HD as SLAVE or SECONDARY drive on a 2 drive SYSTEM, may allow you to boot and THEN try to repartition the drive in order to clean the drive (maybe even get your data before repartiotioning just by copying)
i think it will worth trying that with some pc and a laptop harddisk adaptor for "normal" ide pc connectors.

i thought about this when i remembered a very old but useful utility called "protdrx" that just "as some virus does" stored some boot info on the partition area of a hard disk that prevented you (if you didnt know the password of course) to access HD with write permisions, no permissions at all, write or read from flopppie (in order to keep you out of copying information to/from floppies)
this utility worked at the partition level, and you had no way around it unless putting the disk as slave (you could not boot to floppy since partition info is read first and that one disabled the floppies before boot).

IBM T20 (6:16pm EST Fri Aug 10 2001)
Hi, Nice to see the great non-profit work being undertaken here.

I have a small problem. I purchased an IBM T20 from a workplace clearout (upgrades to company machines). Ive left the company and my machine has a hdd password. The above comments seem to be for other IBM machines. Is there any reasonable way of removing or bypassing the hdd password. I dont think it has a supervisor password but im not sure. any help would be greatly appreciated as it would save me IBMS costly route and also make my machine usable.

Cracked thinkpad password 760ED (6:48pm EST Sat Aug 18 2001)
Too many people have emailed me to reply individually so here is latest progress:

The chip that everyone is seeking is an eeprom located on a 760ED at location U30 which is located on the underside of the planar near the main power connector. The chip is typically marked C46C1 - ST 39AD. It is an 8 pin package and holds the security supervisor data and probably the code required to unlock the embedded code on the hard drive.

I have now obtained 2 of these security eeproms that are new, clear of any password and unprotected but have not obtained a copier/reader as yet. Reading the contents of this would indeed be interesting.
One of the chips was swapped in a SUPERVISOR set 760ED and the thinkpad lost the password immediately but failed to release the original hard drive as this has embedded coding but it did work on a clean formatted one. (will work with various different thinkpad models as well).

As for the hard drive......
If the original chip is removed carefully and read subsequently then the hard drive can be unlocked following the successful supervisor removal but this has not yet been done by me as I really could do with some free time and a copier/reader or maybe some trustworthy soul would like to attempt a copy and return of the second chip ( UK please ).

Cracked thinkpad password 760ED (7:04pm EST Sat Aug 18 2001)
Sorry, forgot to mention...still have the dirty hardware fix for the 760ED involving an unusual grounding technique on the U30 that will eliminate the supervisor password but this has oddly caused a few violent hiccups to my system recently. I will continue with this and inform you all about it when it becomes more stable. - by Static Sensitive

IBM ThinkPad PassWord Removal (6:23am EST Thu Sep 13 2001)
Hi friends. We CAN remove supervisor passwords from ANY laptops (so, we have repaired many laptops with password problem, and we made all) Possible passwords are PowerOn (it can be removed so easy, remove main batteries, unplug AC adapter, and remove backup battery (some little NiCD or LiIon battery) stay laptop for some hours while capacitors discharges, or short some jumpers to discharge these (like CMOS PW on desktop pcs) for the locations of jumpers see the user or technical manuals of Your laptop or search for it on the NET (all ibm powerOn PW removal procedures are public on IBM WEB sites) SuperVisor, Admin, HDD, and any non User or PowerOn passwords are stored on a security chip and cannot be erased so easy. We can remove it for $99 BUT not to say that we do it only for money, we will do it for FREE for the first 10 guys who ask us. HDD password are stored on the HDD plate (not in electronics) BUT in most of cases it's the SAME as the SuperVisor password, becouse if You set a SuerVisor pasword on an IBM laptop, and it has HDD, it will set the HDD password automatically, and this is the same as supervisor. We cannot restore SuperVisor password from a bare HDD, only, if the laptop is available for this. To remove only hDD password, we have an idea. Try to clear all data by a very strong magnetic field with some electro-magnet. Try television picturetube demagnetiser coil, but we didn't guarantee that hdd will be usable after than, it's possible that it will be total unusable, or with many bad sectors.

So, I talked to Nortek today... (4:53am EST Sat Sep 22 2001)
Hello once again,
In regards to the Thinpad 390e...

Let's just say that I am looking at over $250 U.S. (after shipping) in order to get the "power on password" removed from my laptop and hard drive by Nortek. However, when I spoke to the guy about what was involved with performing this service for me he said, "I really don't know. It's all automated".

I take this to mean that something relatively easy is going on. Especially, since Nortek's lead time on these projects is only 48hrs and then the laptop is back in the mail to you.

Folks, I'm not talking about some little BIOS dilemma where shorting the CMOS battery will work (I've tried that). I mean the "power on" job that also simultaneously locks the hard drive and doesn't allow the system to even boot to a prompt, All you get is the damn lock icon at the upper left of the screen.

I have tried to cross the metal contacts on the CMOS while powering on the computer, but I haven't really had any success. About one try in ten results in the machine going through what seems to be a regular boot up to the point the system does a RAM check. Then the machine hangs. After I turn the power off and back on, the same damn icon of the lock appears and prompts me for a password that I do not know.
I don't wish to replace the system board, shell out hundreds of dollars, or ship my computer out of the U.S.
Please someone help with this. I'm not asking for someone to hold my hand or anything, just point me on the CORRECT path to solving this. Any help from persons in the know would be greatly appreciated.

Thanks. - by

Sorry about my poor english :-)

- by Cleam
reply on Cleam (4:03am EST Thu Oct 04 2001)
The hdd password is stored on the hdd. Therefore you can replace the hdd without any problems except if there are more password set (supervisor, or power-on). You can check this by removing the hdd, and then startup the machine. if there's no password prompt, you can replace the hdd. you can check the supervisor&power-on password in the bios...

power-on password can be removed by putting out the cmos-battery for some time...

crack supervisor password (4:15am EST Thu Oct 04 2001)
to crack supervisor password on thinkpad if you still can boot try:

careful: if the cmos of the thinkpad is reset and the supervisor password is set, you can't get into the system anymore. because the timer is reset. you get error 161 (time) and 163 (date). the system automatically goes into the bios, and doesn't boot. to get into the setup you need the supervisor password... SO...

When my thinkpad boots, its says:
0270, check date and time settings
0251, bad failure checksum cmos
and the the little damn padlock icon, with a little computer in the right buttom corner appears. :I
is it a supervisor password? it still prompts, when i remove HD.
reply on thomas (9:17am EST Fri Oct 05 2001)
It's a supervisor password, because the cmos is already cleared...

what can you do...

1. The supervisor password is stored on a eeprom. You need an eeprom reader to get the password. there's no way to crack the password by software, because you can't boot...
But I don't if the password is encrypted on the eeprom. I think it is...

2. You can send your laptop to Nortek...

IBM and Supervisor Password (6:43pm EST Tue Oct 09 2001)
Entering the Bios (based on power up p/word) and CTRL-D. You another menu set. One of them is for eeprom. Now this is basically HEX shit. Does this in any way contain the password in it? If so, can one change it to, say, all 00's and remove the password? I'd be interested for some of you to go into this menu if you DON'T have a supervisor p/word, note what it 'says', then put in a supervisor p/word and see what it says then. Does it change??

If so, maybe this is a way to remove it? Fuck knows really, just a shot in the dark...

HDD password workaround (10:49pm EST Tue Oct 23 2001)
If the HDD pwd is stored in an EEPROM on the HDD....

Pull out the HDD. Strip away the electronic PCB and replace it with another from a known good drive (same drive of course) and reinsert drive. Reboot and voila!! - This gets the data.

If the pwd is saved to the HDD platters then a s/w remedy is required via floppy.

If the pwd is saved part to EEPROM on the drive and part to the platters on the drive (ie, the laptop won't boot from floppy if drive is pulled or swapped and the drive won't work in another laptop - both are required as well as the pwd!!) then this should also be solve using s/w.

If there's access to the laptop using floppy then there is a s/w remedy.

If your problem is merely HHD pwd - swap the drive's circuit board. - by t0t0
HDD password workaround (5:37pm EST Wed Oct 24 2001)

The HDD password is NOT stored in any memory device on the drive electronics. It is written to the disk platters in the maintenance cylinder along with sector address map and calibration data. There would be little point in making password protection that could be overcome so easily (e.g. just by swapping the PCB).

I am a design engineer working for an OEM and work every day with the manufacturer's design specs for 2½" and 3½" ATA drives. There is a solution for unlocking drives but this information is not available to end users.

HDD password workaround - IBM Thinkpad 390X (12:31pm EST Tue Oct 30 2001)
I have read all of this threa, and have actually tried most of it. Unfortunately I do not have an EEPROM reader. I took the drive from the locked Thinkpad - placed it into another- previously UNLOCKED Thinkpad, and now that one is locked with the unknown password as well. I support laptops at a small school and a student placed a Power-on-Password. Thus I cannot boot to a floppy and so on.

My limited understanding leads me to believe that Nick Allsop's post is unfortunately very accurate. I am tempted to try submitting the HDD to a strong magnet (don't have Degaussing equipment either).

And yes, like everyone here, I cannot afford to send the laptops to Nortek or to Password Crackers Inc. I would have done so by now after spending so much time on this. My supervisor will NOT spend the $799 per laptop for IBM to replace the system board.

The unlocking must be a two step process- the system board itself and the HDD. I am still looking for the appropriate diagrams for the 390X to get closer to the right avenue. The PDFs I get to from Nortek's site is what I already had. I am NOT concerned with Data as we ghost these laptops using Norton.

Further hints seriously appreciated. The closest to a working solution I see thus far is that posted by WAPTEC@pdx

Request for Comments ~ Thinkpad BIOS (3:48pm EST Tue Oct 30 2001)
Hello Again

I have some hope in finding a way to delet the password altogether, as long as data recovery is NOT an issue (for me it isn't, just being able to USE the laptops the school bought for the students is).

I am hoping that a utility called ZAP and/or another utility called WIP will enable me to get past the BIOS pwd. I am presently reading these from the IBM site of all places. I am hoping that f I can get the laptop to think that this is a NEW harddrive install that I will be able to fdisk and later return this laptop to the queue. Yes, I had an Admin password on the laptop but it looks like the student who backed me into this corner was one who used to work for me. (*sigh*) URLs I am referring to:

Any guidance from the IBM employees in our midst would be terribly appreciated.

ibm passwords (9:59pm EST Tue Oct 30 2001)
i got a 760 el ibm off e-bay untested for 35.00 ? i get the machine and there is a password set, after zeroing out the cmos i found that there was a password set on the hard drive as will, that would stop the boot process some place in the post diag's on start up. there is a way around that i hard set the cmos values on my home computer, booted with a folppy and hot swapped the hard drive, once i was in the hard drive i coppyed all the data and reformated the drive. after i reformated the drive it still would not boot up, i latter flashed the drive with manufacture's bios data and it started to work agin ? so it can be hacked, but the price of a new hard drive is not worth the trouble i went through just to get a 1.2 gig hard drive back ? nothing is fool proof and good luck - by jhughes
Thinkpad CMOS or HDD Passwords - simple and easy to remove (11:40am EST Wed Oct 31 2001)
I just cleared the password on one, it took about 1 minute 30 seconds from start to finish. I cannot believe people are considering replacing motherboards or paying hundreds to have the password cleared.

Remove one screw.
Remove CMOS and Laptop batteries.
Unplug Power.
Wait 30 seconds.
Put both batteries back.
Put in screw.
Plug power back in.


Hard drive password, that would take 4 minutes from start to finsh. Remove drive, get a $5 adapter so it'll work on a PC. Plug it in to a PC as a secondary HDD, and then either find and delete the password file, or just wipe the drive.

If you still can't do it after reading these instructions, I'll do it for our minimum $50 bench fee- you pay the shipping. - by Dv Supply
Thinkpad CMOS or HDD Passwords - simple and easy to remove (10:58am EST Thu Nov 01 2001)
Dear DV Supply

I am encouraged by your email. Unfortunately I left the CMOS and battrey pack out for an entire evening. Was it a Thinkpad you had ? I have 390X Thinkpads. The password is a Power-On and thus I cannot use a software solution. The BIOS is set to HDD only, thus I cannot boot to floppy. I have attempted a "brute force" method of trying to short out EEPROM to no avail. The laptop aks for the POP even WITHOUT the HDD. The Library in which I work might happily pay you $50 if you can assure me I will be able to boot to floppy and reformat the HDD. What have I overlooked ?

Thank you for you time and expertise. - by Julia
Can't even access the HDD when mounted as a slave in D/T (8:05am EST Fri Nov 02 2001)
DV Supply, have you actually tried mounting a password protected HDD in a desktop and fdisking it?

The password protection is part of the ATA3 specification. The controller won't allow any access to the drive while it's locked, other than to remove the password.

MS-DOS, Win98 and Win2K won't even recognise the drive. VxWorks recognises and mounts the drive, but won't allow any access to it. I'll try Linux next, but without much hope of success. I have a spare controller from an identical drive, but it looks like it's not even worth my while trying to swap that over.

Short of swapping or degaussing the platters, I have no idea where to go with this, other than sacrificing a chicken and praying to the Dark Gods. I suspect Nick Allsop above might have an idea though. Nick? Help us Obi Wan Allsop, you're our only hope. - by Colin MacDonald
HDD password lock (12:30pm EST Sat Nov 03 2001)
Hi Colin
As you will probably understand it is not possible for me to give the 'official' method of cracking the HDD password and this in any case requires a small amount of hardware.

However I can tell you that the drive controller checks for the password protection only once at startup. Also that the data on a 'locked' drive is not encrypted.

Therefore after successful calibration on an unlocked drive, the drive controller is in a condition where it can read data from the disk platters and no subsequent check for password is made until the drive is powered down or is put into sleep mode (using the appropriate ATA command).

So you will probably have guessed what you could try should you have a second unlocked 'donor' drive of the same model & firmware revision.

This method if done properly will allow one to bypass the password lock to gain access to data but will not reveal what the original password was. To do that you must use the 'official' method, which on a drive from a DELL or IBM Thinkpad machine reveals what the original password was, in plain text (or in encrypted form if from another type of laptop).

Please note that the two controllers must have an IDENTICAL firmware level otherwise corruption of the data (due to sector mapping errors) may occur. The firmware level is available as an ASCII field in the IDENTIFY information returned by issuing the IDENTIFY DEVICE ATA command (0xEC). This will work on a locked or unlocked drive. Also please note that the above 'bypass' procedure could damage one or both controllers if not performed properly - you have been warned!

Hope this is of some help...
- by Nick Allsop
Cheers Nick (8:17am EST Mon Nov 05 2001)
Thanks for the reply Nick. Unfortunately, it's not the data I'm after, it's a functioning drive. :(

I'm not entirely sure what you're suggesting. I've already tried swapping the controller from an identical drive (that's dead and grinding) are you suggesting that I whip the controller off of the other drive while it's powered up? That the controller only resets its state if it sees a bona fide ATA command? But I thought the controllers didn't have any non-volatile storage on them? Sorry, am I being dense here?

If this does work, I suspect I still won't be able to wipe the password off the platter, unless it's stored somewhere that one of the utilities on
can get at it.

By the way, I'm pressing on with this as a personal project, not because of economics. It irks me that a drive can be paperweighted so easily. My next avenue is to snoop on what's actually going on in the pins under the label on the logic controller (near the connector). I've already accepted that the drive is defunct, so I don't mind wrecking it further.

Thanks again for your help, - by Colin MacDonald
HDD password lock (6:42pm EST Tue Nov 06 2001)
Hi Colin
The method I described does involve swapping the controller PCB whilst the drive is powered up. Because the controller powered up on a non-password protected drive will, upon completion of the initial calibration sequence, be in a condition where it will be able to read the data from the disk platters of the 'locked' drive, thus bypassing the password lock. However, there is a risk of damage to the controller or disk assembly.

The drive controller contains both volatile and non-volatile memory, but the non-volatile memory does not contain any information relating to the password lock - this is stored on the disk platters.

Unfortunately this does not give you a way of removing the password protection from the drive completely. However I may be able to help, please advise exactly what the model of the (functioning) drive you wish to unlock is.

BTW, the pins you mention carry the head signals to and from the read/write amplifier (a chip mounted inside the disk assembly), the voice coil motor drive signals (voice coil motor moves the headstack) and the head select control signal.

Regards - by Nick Allsop
Drive details (10:24am EST Thu Nov 08 2001)
Nick, the drive model is DBCA-206480, 6.49Gb, manufactured October 1999 (yes, I'm that cheap).

I'm genuinely surprised that hot swapping controllers works I'd expect the controller to hold its current state in volatile memory, and to reset to a state where it will check the password if it is hot swapped. Still, stranger things happen at sea. -)

I had a look at the pins - or to be more accurate, my workmate (hi Russell) had a look at them - but couldn't make out anything sensible on an oscilliscope. Fun though this is, I don't think we can justify rigging up a custom harness and poking at it with one of our workplace logic analysers. -)

One year plus, still no answer.. (12:07am EST Fri Nov 09 2001)
Over a year on this topic..
Still no reliable way to:

a) Hit the freaking little 8pin chip on TP motherboards with (your suggestion here) to make the password go bye bye
(which one? where issit? Please refer off the cuff to majik eprom readers/programmers/dilithium crystals)

b) depassword a TP hard drive so it can be used again.. (Is the PW stored on the CE cyl? Confirmation? How 2 read it?)

My little headache is a TP 365X, supervisor p/w set, HD p/w'd. No $ for Nortek.

BTW: A degausser will probably induce stray currents in the HD circuit board and fry the HD, if it dont SHAKE the heads off the arm first.. I have an old radio station reel2reel demagger and it did some fine damage to older regular IDE drives that I got frustrated with in the past..

Thinkpad X20 Fiasco/security (6:09am EST Sun Dec 09 2001)
Further To be blunt I am NOT impressed by all this NONSENSE masquerading as security in
the interest of the customer, how good are sales of system boards and hard drives at
IBM these days?.

What god given right does IBM have to make my drive non functional without
warning me.

In this litigious world I am surprised that no one has sued IBM yet, I hope I am not
the first or last.

Here in Australia we have the Trade Practices Act, which is rather tough on
corporations that engage in misleading and deceptive conduct.

And isn't this all misleading and deceptive?

1. There is a separate password for HDD in the x20 bios. Yet if the supervisor
password is selected it also silently without permission or knowledge of the
owner also passwords the HDD.
2. The removal of the backup battery for testing or replacement is a common
thing to do without causing a disaster of this magnitude.
3. It is not true that IBM cannot correct all these problems once the customer
proves ownership. The same equipment that breathes life into the system
board can also revive it. If not then it's a bad design and the design needs to
be rectified.
4. As someone else in this forum has correctly pointed out there is very little
about this on the IBM website about any of this apparently secret security

Nick is the Man (4:32am EST Mon Dec 10 2001)
To by 390e in waiting
The password on my harddrive is not the same as yours. You have to send the drive off to be unlocked. You'll receive the password by mail. You can then unlock your laptop with that password and remove all passwords from the bios. Once you have paid using PayPall, you'll get your harddrive back. Plug it in, format it (if needed) and reinstall the laptop. Worked fine for me.

I have another problem concerning an X20. I knew the drive in this machine was not the original drive. Nick unlocked it and gave me the password. Since it wasn't the original drive, the password did not work in this X20.
My idea is to do the following:
Once the drive is returned, I'll format it on a different machine. I will then stick it back into the locked X20 hoping it will lock the drive with its current password. I'll send the drive back for unlocking and hope the password I'll get then WILL work on this thinkpad.
Anybody has any idea if this might work?

The BIOS is there in full view in any of the FLASH BIOS UPDATES.

pw (9:16am EST Fri Dec 14 2001)
The password protection on IBM laptops is made to stop theft. This is because theft of Laptops is a huge industry. I know a few people who deal in stolen laptops & say they will not touch IBM laptops because of their password protection.

All the people here should learn from this and put a password in place so NO-ONE can accidently change it!

Good on IBM for making it hard. But they should have a cheap easy solution for genuine brought laptops. - by john

pw (8:50am EST Sat Dec 15 2001)
I agree with John, however IBM does NOT have a cheap solution for genuine owners accidentally caught up in this fiasco, IBM's response is to replace the system board for $1500 Australian plus or minus $200 depending on labour and it takes over a week. IBM also say they do not repair boards to a component level. If you examine a system board as I have, (took less than 5 minutes to remove first time) there are a lot of very minor components which can and will fail, this is ridiculous, I am sorry I purchased this second hand thinkpad, however I will not give up till I solve it and publish my results on the Internet, that should put an end to all the firms who want to make you jump through hoops, charge an arm and a leg, saying they use sepcially developed software and firmware. the super duper secret password(s) are in a serial eeprom Xicor X24C08 marked as 24RF08CN, it is near the line input socket under the system board, more to follow. - by Joe in Australia

access for 560x pap/pop protected (3:12am EST Tue Dec 18 2001)
I found a (little) solution to get access to a pop/pap protected 560x, even if this machine is not completely back to life. If you did not remove the backup battery, leave it where it is. Removing it does not solve any pop/pap prob but causes some new. For most tps there are detailed descriptions available in the hardware maintenance manual, how to remove the pop. You will find a link on
#Power from where you can select your model. You need another tool available on (thanks to Bob Eager for this). It is called refstamp and allows you to boot into your machine even if there are errors (specially the 601/603). The hardware maintenance floppy (and some others from IBM) have a special stamp at the very beginning of the floppy. This tool creates this stamp. If you did disassemble your machine (to short the jumper for removing pop), remove the harddisk too. Create a dos start floppy and prepare it with refstamp. You will be able too boot from this disk. What comes now sounds destructive, but it works. Into the running machine hot plug the hard drive. You have to do it in the correct direction. The connector of the hard drive do have a 40 and a 4 pin block. Start to attach the 40 pin block from the side, where the 4 pin block is located. This is important. The last 4 pins of the 40 pin block are the power connectors. These have to be attached last. This will let you get access to the machine and the hard drive. Pleas be carefull, you might destroy your hardware. I did this action with a fujitsu (which was the one originally attached and pw protected in my machine) and a new IBM harddisk, both works fine with this. I prepared the IBM harddisk with refstamp too, but it won't let me boot. You will need a floppy for that. So now you have some kind of access to your machine. Until now, I have no solution, how to bypass the errors without a floppy, but working on this and will let you know. - by hijob
again access for 560x pap/pop protected (5:39am EST Tue Dec 18 2001)

Nick is the man (8:59am EST Tue Dec 18 2001)

because I'm not sure if Nick's e-mail
address posted in this forum is still
valid, I'm submitting my problem with my
TP 760 ED also here.

So here ist goes:

The TP booted sunday morning, showing error 163 and 173
on boot, indicating a loss of configuration data.
It entered the Easy Setup menu, prompting for new
time and date. I entered the valid data, the system
started up again, booting fine, without asking for
a PowerOnPassword, which normally was set.

So no major problem I thought, trying to reboot
and entering the setup via SuperVisorPassword
and that won't work. I can enter the setup by
entering nothing, respectively push Enter at

But this doesn't give me the ability to change
any advanced setup features (PowerOnPassword,
SuperVisorPassword, HD-Password).

So it seems the system somehow is using a
SuperVisorPassword which I haven't set.

The major problem is that, as you might already know,
setting the SuperVisorPassword also sets the
HD-password and now I can't change HD's
(normally using Windows (2,1 GB IBM org. disk)
and Linux (Toshiba 6 GB replacement disk)).

To make it clear, once I've set up a PowerOnPasssword
and a seperate SuperVisorPassword, and now
the PowerOnPassword is gone, the SuperVisorPassword
must have changed somehow.

Now my questions:

As Nick already did some successful HD pw recovery
would this also be a solution for me, because
HD pw and SuperVisorPassword must be the same
in my case, or am I wrong?

I'm living in Germany, Nick, I guess you are living in the UK,

Would it be possible that I might ship you the drive?

Would the drive be damaged during your pw-recovery?

What would be the costs for your work?

Thanks a lot in advance for your help
and time spent answering my mail.

A pattern emerges, passwords are stored in eeprom in Tpx20 and tp380 possibly others, as 7 bytes in IBM MF1 scan codes followed by an 8 bit sum of the preceeding seven bytes, simple way to find is to read eeprom, scan till the 8 bit sum of last seven bytes equals current byte go back seven bytes decode using MF1 scan codes, there is your password, it is NOT case sensitive, so type it in either upper or lower case. Also at least in TPx20 they are turned into 0FFh's as the TP boots so no use to try and find once TP has booted either in DOS or Windows.

Atmel datasheet says that 24rf08 is compatibel with the normal 24co8 chip without the receive transmit part, but the 24rf08 has 14 pins and the 24c08 has 8 pins. Maybe someone can help with the pinout of both chips. the 24c08 is cheap and easy to buy but the 24rf08 they won't sell in the netherlands. Any suggestions/help wil be most welkom.
sorry for bad english

HD Password Removal (8:04am EST Mon Dec 31 2001)
Anyone tried booting from a floppy disk (DOS or Win9X) and then from the DOS prompt typing: a:\fdisk /mbr

The /mbr is a hidden and undocumented option in the fdisk command. It will remove all data in the boot sector of the HDD, including the Hard disk Password if one is set. It worked for me on a Thinkpad 600x. - by /mbr
RFID on X20 and others (12:59pm EST Mon Dec 31 2001)
Has anyone contemplated SEROIUS implications of RFID as on TPX20 and others using AT24RF08CN, the RFID transmitter has full access to read and write the entire eeprom including changing your supervisor password with no power applied, so I walk into an office full of x20 and change all the passwords F..KIBM. Yes the security bits are there but at times, for example when the lock symbol is displayed, all security bits are off, FULL ACCESS to RFID, I know this from reading 16 bytes at B8 Access protection page on serial i2c bus with TPx20 functioning. I Suppose this gets around, NO ONE AT IBM FORCED YOU TO ENTER A PASSWORD SO PAY FOR A NEW SYSTEM BOARD. - by Joe in Australia
X20 Access protection page (2:28pm EST Mon Dec 31 2001)
this is what the access protection page is set to int the AT24RF08CN when a ThinkPad x20 is displaying the padlock waiting for a password
B8 = FF, FF, FF, FF, FF, FF, FF, FF, FF, FF, 7E, FF, FF, FF, FF, 49

That means that full access via rfid for reads and writes is on, I can read the password using rfid and enetr it its that simple, THIS IS SECURITY? Why are we zapping eeprom when it can be done by swiping the x20 near a reader.

And IBM still dont know how to unlock an x20 without replacing the system board for highway robbery prices, misleading and deceptive may be far too kind a description in this case. - by Joe in Australia

If the HDD password is store in a security chip, It is impossiable to use low formatting to clear password, perhaps, :-). PC bios access HDD use INT 13 function, below that, use I/O port, can we use the I/O port operating the HDD as boot with floppy disk? - by John

locked the harddisk by the supervisior password witch I forgot
and now I can't change setting in BIOS and open the harddisk.
All I know is that the harddisk and supervisor password are the same.
I wanted to ask you if there is any way to find out what is the password?

please send me an answear by e-mail

Re: request (9:25am EST Sat Jan 12 2002)
Hi Yakov

I can unlock your HDD and recover the password in plain text, so you can unlock your laptop. The procedure is non-invasive, does not delete or change the stored data and does not damage the drive. You will need to send just the drive to me in the UK.

If you are interested, please send me email.

Solution to the biggest problem (6:15am EST Thu Jan 17 2002)
Hello Sulaq, what problem? reading an eeprom is easy, decoding not difficult either, when IBM in a pitiful effort to bolster its illusion of a secure password system, offered no policy to assist their clients, their bread and butter to recover from what is a normal foreseable event/accident, they forced their now EX-customers to find a way to ridicule IBM and prove that their so called security is a pathetic sick cruel hoax, you dont need to be Einstein to figure out that the IBM password thingo super dopey gizmo can be defeated. There is ample evidence to that effect here. IBM's solution is misleading, deceptive and their conduct is reprehensible. Save your money and ours, let them bribe YOU for your silence and share the loot with US.

Solution to the biggest problem (9:32am EST Tue Jan 22 2002)
If you've got it all dismantled, look for an eeprom, it will most likley be an 8 pin chip but could be 14 pin chip.

You are looking for a part number AT24RF08CN or similar, or 24C01 or 24C02 or 24C04 or 24C08 or ohters that I have not come accros yet.

If you have no knowledge of electronics, find someone who has, a hobbyist or some one at college or uni.

Tell them you have an i2c (I square C) eeprom you need to read.

Before unsoldering, note the orientation of the chip on the board.

They, you will need to unsolder it to be able to read it, this requires very good soldering skills, or you risk damaging the board.

Have them read it.

Then it will have to soldered back in, there is no need to obtain a replacement.
email me the contents of the eeprom, it's only a short list.

I will look at and decode decode the listing and tell you by return e-mail what your password is (FREE)

Previous to this everything was fine, but I could never change the boot devices which annoyed me. Now this is worse, no laptop at all. What do I need to do?

Know the password but it doesnt work! by kirby (6:50am EST Sat Jan 26 2002)
Kirby, the only thing I can think of is if you had previously unsoldered the eeprom and did not solder it back correctly, or the SDA pin has lifted for whatever reason. Specifically on some models if SDA is left disconnected, the thinkpad will behave as if no supervisor password is not set (doesn't work on all models only some and I don't remeber which, only seen it once) in that case the password cannot be reset because you cannot ever write to the eeprom, ensure SDA pin on eeprom is soldered back. - by Joe in Australia

Are you following the user manual to the letter, I think it was on a 600, I encountered something similar, and it took me a while to disable password, you have to do exactly what the manual says, and the on screen prompts (THERE ARENT ANY) are not helpful, you could say hopeless in fact. - by Joe in Australia

Hi GEE, I don't visit here often, you should e-mail me direct, to asnwer your question, No, you are looking for an 8 pin chip small SOIC surface mounted, amongst the writing on it you might see 24Cxx, where 'xx' could be 01,02,04,08 or look for an ATMEL AT24RF08CN or a 14 Pin surface mounted small TSSOP with writing on it like ATMEL 24RF08CN or C something, if you find both a 24cxx and a 24RF08 something, then it's most likely that the password is in the 24RF08 something, if you only find a 24Cxx then the password is in that. - by Joe in Australia

"Y don't need "Joes Monster Reader"" interesting, and the only eeprom reader that you could test read an 24RF08 was "very expensive (the one and only) commercial reader capable to read/write 24RFXX". My reader has 2 IC's and according to you it's a monster! how smaller or simpler was this very expensive commercial reader?

Password not encrypted in 24RFXX, so you are saying we can read with PonyProg and see results in ASCII on right bar?

IBM Passwords (5:36pm EST Sun Feb 24 2002)
Hi Guy UK

I am in the UK and can unlock almost any model of hard drive, plus give you the password that was used (if drive was locked in IBM TP or DELL machine). This password is the same as the BIOS password in almost all cases and should allow you to unlock your laptop.

All I need is the HDD, I only charge a little cost for my time or nothing if you don't want the HDD back. In any case you don't send any payment until I've sent you the password by email (usually same day I receive HDD).

The procedure does not damage the drive or delete the data on it.

If you are interested, please contact me via email.

Hard drive password (1:58pm EST Tue Mar 05 2002)
There's no way at all the drive password can be removed if you don't know it. It's just not possible according to IBM - not even THEY can do it. None of the ATA read/write commands will work when the drive is locked and - according to them - the password is encrypted and stored with the firmware on an inaccessible area of the drive anyway. Other manufacturers like Toshiba and Hitachi probably use the exact same method. Also according to my info from IBM, there's something called a 'master password' that they can use to erase the drive, but that it's different for every individual drive (can this really be true!?) They must have some rather long password lists at IBM... - by wish it weren't true

Whether you have access to the floppy drive or not doesn't matter.

HD Password (9:01am EST Wed Mar 20 2002)
I have recently bought a thinkpad 560x for my sister and decided to experiment with the protection mechanisms a bit.

I can boot the notebook from floppy to either DOS or Linux as long as the disk is refstamped. To my surprise, I was able to access the HD from Linux while it is not detected from DOS. Does this mean that the HD lock mechanism can be dodged by using another OS? Which password combinations do I have to set in order to protect my data?
- by Mike
TP and HD Password (5:59pm EST Thu Mar 21 2002)
To Unhappy in it, I don't know of any other solution, you have to gain access to the eeprom, there is no easier way, on some models it is very easy, on others it's a complete strip down @#$*&, that's life.

To Mike, booting from a refstamped floppy, OK, But was your HD password locked? are able to access HD by simply booting from the refstamped floppy? I doubt it. As regards safer password combinations, ensure you have a mix of alpha and numerals. - by Joe in Australia

IBM Thinkpad password recovery (2:35pm EST Wed Apr 03 2002)
First, I will ignore the stupid remark about a "Magic Disk" that can be used to remove the password from a hard drive.

Yes, in many cases it is possible to install a password protected hard drive in another Thinkpad, boot up on a floppy disk that we do have and remove the password.

Enough said about that. We have developed a tool that allows for the recovery of the information stored in several of the EEPROMs, namely the following: 2401, 2402, 2404, 2408, 2416, 2432, 2464, 24128, 24256, 9346, 9356, 9366, 9376 and 9386.

Most of the time we only have to desolder 1 pin on the chip in order to recover the file, in other cases we have to remove the chip completely.

We are planning on making this tool available to any competent repair facility, once we complete the development.

The chip you want to read is the 24xxx chip.

We have not yet finished the tool we are working on, but at this point in time we can read the content of the chip through an interface that we have developed. On some units the chip has to be removed completely, on other units we only de-solder 1 pin.

Thanks guys for quick responce.
upparently there are 2 24XXX atmel eeproms on motherboard one is 8 pins , the other is 14 pins, which one to read from?? then i found the daallas eeprom staring like 17XXX.
once again thanks a lot, at least i am on the right track. - by Vit_GM
TP 600e (11:17am EST Sun Apr 07 2002)
The EEPROM you are looking for is the one located on the back side of the board, it is located very close the a large chip that has got PCIbus written on it. Turning the board upside down, with the prots facing you, it is located on the right side of the board fairly close the the ports.

We are NOT selling any tool, nor are we planning on selling it to the general public, we can however retrieve the passwords from most of the chips at this point in time. In many cases without un-soldering the chip from the board. - by ardec1

Hard Drive Password (2:25pm EST Thu Apr 11 2002)
I have read quite a few comments about the utility disk that we use to unlock the IBm laptop hard drives with.

This is NOT a utility disk that we developed, it is an older UNIX/LINUX utility that we have around.

If anybody would like to give it a try, email me at:

and I will email you the two files that are used to create the disk. You are going to need one formatted 1.44Mb. floppy disk, and if you are not familiar with RAWRITE, you are going to have to either send me an email or give me a call so I can walk you through the procedure for creating the disk and using it.

Don't expect an instant response, I do have to work for a living too.:o)

Correct. The power-on password will stop them dead in their tracks.

>B) If somebody would remove my hard drive and put >it into an other computer. Could he read my data >or would he still need the "Hard disk"-password ?

That person would need to know the hard drive password even if the hard drive was was in another ThinkPad.

Just NEVER FORGET YOUR PASSWORDS!! You'll need a new hard drive and system board if you do.

Hope this helps.

RE: IBM sucks! by capu (11:30am EST Fri Apr 12 2002)
As far as the hard drive goes, what IBM is saying is not exactly true.
I purchased an IBM 770 on eBay that had all the passwords set.
Plugging the drive in another Thinkpad and running the utility that we have on the drive allowed me to reset the password for the drive and read the content of the drive.
I wiped the drive clean and after getting irritated enough at IBM, we developed a little tool that we can use to read the content of the EEPROM, after that it was pretty much downhill all the way.
We can now read the content of nearly all the EEPROM chips, at least the 24xxx and 93xxx series chips. - by ardec1
Free Soloution to Passwords (12:56am EST Sun Apr 14 2002)
Aftre reading all this I was a little dismayed. However we found inside our 760c Thinkpad a little connector which you can add a jumper to which clears the password

First you have to open the computer and pop up the keyboad
Then remove the HDD and Floppy
Look at the left hand side of where the floppy was to find a tiny hole with two connectors inside
Put a little paperclip or staple in there to touch the connectors together and leave it there
Now put the HDD and FLoppy back and restart the puter.
Now when it asks for a password just press enter and there you go , no more password.
Hope this helps someone and saves them $1600 NZD :)

Tying WP high on 24c01 (12:51am EST Sun Apr 21 2002)

My schematic is for READING an unsoldered 24C01, I do not want to WRITE to it, not even accidentally.

Connecting WP to high logic level (VCC) IS CORRECT, that disables writing yet ALLOWS READING EEPROM.

We only need to read eeprom to recover password.

If by any mishap a byte is altered in the eeprom, then the TP will return CRC errors etc, then you have to guess which byte to correct, a tall order.

Coonecting WP high avoids all that drama.

To guy in Canada with X20, I have a new interface on my web site below, that uses only 1 IC a 74LS05 and some resistors, powered by 3 penlight batteries and connected to PC serial port via DB9 can't get easier than on an X20 which doesn't have to be dismatled.

Dump of eeprom (2:04pm EST Sun Apr 21 2002)
Could someone send me a dump of their eeprom.I figure if you dumped an image off a thinkpad with no passwords, and wrote it to the eeprom of a password protected thinkpad, it would work for getting rid the passwords. I also made an I2C eeprom reader just using resisters and the parallel port, It gets it's power from the port also. Very easy to do with no 74LS05.I also have a program to wipe the password off the harddrive. Gimme a few days, and i'll do up a zip file of my work and post it on ftp. - by Bill
Dump of eeprom (6:39pm EST Sun Apr 21 2002)
It is easy to use Parallel port, no argument, BUT it is also very easy to damage integrated parallel port on motherboard.

Drivers are required with Windows 2000, NT XP to access LPT port, drivers are messy to install and can interfere with other programs and drivers already installed.

Very difficult if not near impossible to damage RS232 serial port, using serial port and one 74LS05 to avoid all these hassles is a SMALL PRICE TO PAY.

Drawing power form LPT port is a hit and miss affair, 3 penlight batteries are not expensive, the circuit will only be used for a few seconds to read one eeprom.

Program to wipe password from hard drive, I cannot see how you are going to do that.

The ATA IDE interface ignores all commands (other than unlock followed by correct password) how does your software get past that without supplying the correct password.

Dump of eeprom (6:45pm EST Sun Apr 21 2002)
I forgot to mention, copying an unlocked eeprom to a locked eeprom will unlock it, tried it, it works.

BUT, it will also change the serial number UUID MAC etc, it may create problems down the track.

Also (and this not a nice side effect) if the hard drive password is stored in eeprom it will overwrite that and you will never know what it was. - by Joe in Australia

Dump of eeprom for Frank (11:20am EST Tue Apr 23 2002)
Each TP model has slightly different layout for eeprom contents and where CRC and checksums are stored (don't ask me how to edit these, I only read and recover passwords)I don't write to eeprom.
Each individual TP has different serial numbers UUID, MAC, bios settings etc stored in eeprom, when you copy the eeprom from one TP into another you are also copying the serial numbers etc, you end up with 2 TP's with same serial numbers UUID etc this may be a problem if you use both TP's with same MAC on a network for example.

I don't know what security chip sellers do, I Imagine they sell an eeprom with blanked out serial numbers, I am only guessing. - by Joe in Australia

Password recovery (10:18am EST Wed Apr 24 2002)
We have been working on a tool that can be used to read the content of the EEPROMs, at this point in time only the 24xxx and the 93xxx series chips.

It connects through the parallel port on pretty much any machine, I am using it with an IBM 560Z laptop.

It uses a clip made by 3M that clips on to the EEPROM and it is powered by a Radio Shack 12 volt power supply.

That is how I recovered the EEPRO dump that I posted earlier.

The file is in Intel .HEX format and part of it can be read using the debug utility.

Move the file in to a directory, open a DOS session, change directory to the directory where the file is located, type "DEBUG" at the prompt and type "?" to get the debug commands.

I am not a developer, I am relying on some of our developers to come up with a solution, if anybody here are willing to work on this problem, I will be happy to supply all of the information that I have.

The main goal here should be to find a way to break IBM's stupid monopoly. - by ardec1
Password recovery (10:44am EST Wed Apr 24 2002)

Password removal (10:49am EST Wed Apr 24 2002)
It is supposedly possible to hit the EEPROM with UV light, that should remove the password from what I have heard, haven't tried it.

As for the hard drive, somebody told me that in their production facility they use a "BIG" magnet, they place a large magnet on the drive, that supposedly "Scrambles it" and the drive can then be low-level formatted and used again, haven't tried it either. - by ardec1
And finally a heads-up (12:02pm EST Wed Apr 24 2002)
I received an email from some guy in Russia who claimed that he could recover the password on any IBM Thinkpad.

That may be a totally legit offer, but on the other hand, I would be somewhat hesitant to send my laptop to him, he said that he needed the laptop in order to recover/remove the password. First of all, the cost involved in shipping the laptop back and forth would be rather high, and unfortunately I am of a somewhat suspecious nature, the laptop may never come back.

I would urge anybody who received that same email to be cautious until he provides more information. - by ardec1

For the 390 series, I would recommend using a SOIC clip that can be purchased on-line from Time Motion Tools in San Diego California, it eliminates the need for any soldering of wires on to the chip, it simply clamps on to the leads on the EEPROM (it is made by 3M and they make clips for nearly all the various EEPROMs) the part number I have on my invoice is: BID-923650-08 8 pin SOIC S BID, Time Motion Tool part number: TMT-650-08.

Thinkpad HD cracked (9:10pm EST Sat Apr 27 2002)
By using some free software I found doing a search for "INT 13H" commands I was thinking of using to directly wipe the HD (didn't work BTW) which allows you to view and edit a hard drive directly I used an old compaq lte as a platform to view the drive. I loaded up to a drive which had similar specs (both had 16 heads but they were way off on number of sectors) did a directory of the good hard drive and after I exited through the error reading disk's that came up at this point I removed drive one, loaded drive two and then loaded up the hard drive snooping software.
On a page near the end of the drive I found a small patch of text (in the keyboard code format) sitting out in the middle of a bunch of 00's. I decoded this back to characters, put the drive back in the laptop, and voila it worked.
one caviat to this is I dont know if I damaged the hard drive data with some of the other things I had tried before had, but it would not load up afterward and I did have to do an F-Disk / format to get it to useable.
As for other suggestions on the board, Fdisk /MBR does not fix the problem even if you get through to a DOS prompt. The easiest way after cracking the code is to just let the BIOS software do it for you (at the lock, type in the password hit the space bar and enter and it's gone)
So there it is just a little search and destroy is all it takes, please note it probably would have been easier to do if I could have had a hard drive with the same parameters but you might not even need that. It would probably be real easy if you picked up a 2.5 to 3.5 IDE adaptor and just did it all on a main computer but I wanted to do this with stuff on hand.

1 load up your main computer using the hard drive which is workable in the seconadary position
2 in DOS, do a DIR on the hard drive (I saw errors at this point but if you have 2 drives which have the same heads and sectors you might not)
3 the tricky part : hot swap out the protected drive for the normal one
4 using some small disk sector editor (the one mentioned above worked for me, I am not including his web address since I haven't contacted him and I dont know if he wants it associated) locate the password:
5 I was successfull in about 10 minutes after I got to this point, I used some of the commands in the editor to go to the last sector and it provided me a way to see the partition information so I knew I was in the MBR, looking over the information I found a section which had a block of what looked to be keyboard codes (1H to 32H) which were translated out.
6 reinstall the hard drive into the laptop and when asked for the password enter it. I got a little arrow saying it was going on (you can also remove the password in the usual way at this point) - by HDcracked

The program you mentioned does show me a lot of 00's (zeros) but i can not find anything else (i will keep on searching as i write).
It also says "Error reading LBA sector #" every time i change to the next or previouse sector...???

HDD Password Lock Explained (6:19pm EST Sun Apr 28 2002)
There seems to be so much confusion in this forum about hard drives that are locked with a password. Let me clarify a few points to save other people some time.

1) THERE IS NO software solution that can be used to remove a password lock from a hard drive. The password lock is a built-in function of the drive at hardware level. When locked, the drive rejects all attempts to access stored data. Using BIOS to attempt to read sectors on a password protected HDD will usually return an error code such as 'error reading sector' or 'device not responding'.

2) The password used to lock the drive is an 'encrypted' form of the supervisor / user password chosen by the user and typed in at the keyboard of the laptop / host computer. The password takes the form of from 1 to 32 bytes.

3) The password lock has absolutely NOTHING to do with the operating system, Windows passwords, encryption software etc. You can lock and unlock a hard drive regardless of what operating system is installed and even if there is no operating system installed.

4) The password is stored by the hard drive in a 'hidden' cylinder on the actual magnetic disk platters inside the drive. It is NOT stored in any place on the drive electronics so changing the drive PCB will not unlock a locked drive.

5) The good news... It is possible to recover the password and unlock a locked hard drive. However to do this you need specialist hardware to allow you to access and make sense of the appropriate area of the hidden cylinder(s) on the disk platters.

I hope this clears things up and stops the nonsense about DOS/Linux/Windows/OS-2 etc..etc... software utilities that can unlock hard drives. Basically if such a utility appears to do this, the drive was NOT in a locked condition in the first place.

more stuff on unlocking (9:45pm EST Sun Apr 28 2002)
This is a documented case from me, I did in fact use the afore-mentioned software in the manner described to unlock a hard drive which the lock was set up on a 380 series thinkpad laptop. The code used is encrypted but only with standard keyboard scan codes (1 = 02H Q=10H A=1EH etc, the key scan codes are also available online all over the place) One thing I would recomend is to not use Windows, there is much to be said about going through good old fashioned DOS in a case like this.
I did constantly have errors as well but it did seem to scan the hard drive correctly. Do not forget to do the directory (DOS DIR command) before changing out the hard drives that seemed to be real critical as well since without doing that it would only bring up 00's.
also be sure to go to the end of the drive, there is a simple keystroke in the software I used that would take you to the end. If you are in the right section then (the master boot record) you should be able to view the partition information. once there then start backtracking one page at a time untill you find a section where about 1/4 of the page is 00's with 1-8 characters (Will be in the 01H-32H range) are visable. That should be the password. - by HDcracked
ohh and DJPJ (9:53pm EST Sun Apr 28 2002)
By the way your description of what you have seen is very similar to what I saw. if you were going through windows I recomend making a DOS boot disk and booting up to that, I used a DOS boot disk exclusively when I cracked through my locked drive. It is also possible that there was something in the old Compaq LTE 4/33 laptop that I used as my base for the tests that allowed me to sneak my peek at the hardware.
The funny thing is all I did was re-create all of the information which was available on this chat board to get in.
Well good luck out there.
I will say that there are a few others who have posted to this board who now are offering services (one wants $50 and the other $25) of removing these passwords one from the HD side one from the motherboard side. - by HDcracked
re: more stuff on unlocking (6:44pm EST Mon Apr 29 2002)
Hi HDcracked

The method you describe of hot-swapping disks and using a sector editor under DOS cannot have been on a hardware locked drive. When a drive is in a locked state, no access to the data area of the drive is possible. Your sector editor would have returned an error when attempting to read sectors of data (or maybe just a buffer of zeroes). So being able to read the partition table, MBR or anything at the 'end' of the drive is just not possible. Sorry but I can see no way that this would have worked, unless this was on a drive that does not conform to the latest standards.

BTW you are right that there is a guy in the UK who can unlock drives I think he uses special hardware to do this. There is a website by Joe in Australia that explains how to remove the password from TPs.
- by Nigel White
To Nigel (7:17pm EST Mon Apr 29 2002)
As mentioned this was an older Thinkpad 380 system, that may have made some difference. I used a very old 486 laptop to plug into that may have made a difference.
Doing the DIR of the unlocked drive definitly made a difference since all I recieved was 00's on the locked drive if I hot swapped out without doing this (I believe something to this effect was mentioned earlier when the writer Nick in Nov 2001)
Admittidly everytime even after loading to unlocked, doing the DIR, hotswapping the drives, and then viewing with the sector editor I did recieve an error from the editor, but it also displayd what it read off the drive. It was at this point I was able to search for the password.
And in case you still dont believe it was even locked, when the thinkpad displays a lock w/ a small hard drive at boot up and you cant get past that for anything, the hard drive is locked.

HDD unlock in Denmark? (11:28am EST Tue Apr 30 2002)
Anyone know a company in Denmark who has the hardware to unlock these password locked drives? - by sparx
sparx and other (11:56am EST Tue Apr 30 2002)
Currently I don't have any locked drives to test one of our solutions on.

If any of you out there would like to send me a locked drive, I will be happy to try and run those solutions on them.
I don't want to receive drives from everybody, so please, only about 5 need to respond.

Send me your email address and I will respond with my shipping address.

I will be happy to do this for free, but you pay shipping both ways, so keep in mind that I am in California.

To sparx,

I would like to help you out, but I don't know anybody in DK anymore, it has been too long since I was home last. - by ardec1

Joe in Australia (12:56pm EST Fri May 03 2002)
Thank You very much for your help and persistence in staying with me.
I noticed the posting by "Scorpion" and I think it is distasteful for him to use your enterprise and work to do what he is doing. Your service is a fantastic effort and alternative to the other possibilities out there and you deserve the credit and reward.

I can praise you for the great work and follow-up with me to find my password. The process did not go as smoothly as origionally thought and the one worry I had through out was the information getting erased, changed or damaging ky TP and leave me with Canada, IBM or an unusable machine as my choice. But through your careful guidance, help, concern and promptness, you succeeded in getting me back into my TP without messing anything up. You are indeed a professional in the field. I can highly recommend you to anyone who needs your service and guidance, and can also say I definately got a lot more than I paid for. - by DSpyder

No Hate no regret. (9:08am EST Mon May 06 2002)
Well, this is getting interesting, competition and price wars, wow! I got into this late last year after I was insulted by IBM Australia asking me for $1,700 Australian to replace a system board in an X20 just to recover the supervisor password, the x20 was still under warranty, but IBM said "NO ONE AT IBM FORCED YOU TO ENTER A PASSORD" so it is NOT covere under warranty, they also said that the old system board became their property and they simply dumped them in a bin. I have in my spare time set up a web site supplying information on how the passwords can be recovered from ThinkPad's eeproms and some do's and don'ts if you wish to experiment and do it yourself, I am obviously not going to make a mint by asking for $25 US to supply a password, my software tells you if it has detected a valid set password and only then do you have to pay to receive your password, a lot of people from countries that cannot use PayPal have received their passwords on a promise that they would send payment by postal order afterward, out of about 20, 1 has actually paid, anyway I go on providing the service, Good luck Scorpion. - by Joe in Australia

When the OFF switch does not work. (5:03am EST Tue May 07 2002)
If your TP hangs at any stage and the Power Switch does NOT switch it off.

Try this procedure, works on most TP's.

While Holding down the power button, press F1, F2, F3, F4, F5, F6 then back and forth F5, F4, F3, F2, F1, repeat till it switches off.

This is safer than removing main battery as removing main battery while TP is hung can corrupt eeprom contents leading to CRC errors and a useless TP.

Removing known password (12:40pm EST Thu May 16 2002)
I always thought that if you knew a password, you could remove it by changing the password to blanks. If I read my information correctly, you do this by pressing the space bar once, then enter, when prompted for the new password. Only removes the password if you know the password to begin with. - by Xopher

Maybe IBM should go with making cars (12:17am EST Tue May 21 2002)
Maybe if IBM started making cars, and you accidently locked your keys in your car, they could then say
'Sorry! We cant unlock your car for you, you have to buy a new one!

Man, think of the amount of money they'd make through car sales! :)

Or maybe they could just say, Sorry, you'll need to buy a new engine, computer, gearbox and suspension to fix your locked keys problem.

Now do you think people would complain about that? Would the average person say 'Get stuffed, i'd rather buy a Honda!' Would it be legal for a car manufacturer to charge you for all new parts just because they designed them to not be changable to a new set of car keys? Sorry sir, you lost your car keys? You'll have to buy a new car now because we cant make new keys for your car. HAHA! - by Hamish
Wolf.2501 (9:20pm EST Tue May 21 2002)
I got an email from a person who had used that utility on the 600 dump that I posted, he suggested that the password may be either "RQEDWW", or "EETQWQ"

If he reads this and want to offer his help, everybody may benefit from that.

Remember that the IBM password can only be 7 characters long and can only consist of letters and numbers, no special characters. It is NOT case sensitive either, so it does not matter if a password is entered using upper-case letters or not, it will only be
read by the system as lower-case.

TP EEprom/HDD Unlocking (11:19pm EST Tue May 21 2002)
I work for a small IT company in Melbourne, and have lots of access to Locked TPs (760,s...560s etc). I also have a bunch of 760's with HDDs that I matched up, with passwords (All the same) labelled "Password A". FUnny that IBM think it is a security issue?? I know where the owner of this one laptop lives.....his phone numbers...his salary...his wife's name...where he was born.....his company's asset details....his 2 child's names..the list goes on....*scratching head at security*

Perhaps I should post his information publicly....all over the web??? Wouldn't that be embarr*ass*ing for IBM??? (No I won't, he is innocent, IBM are the guilty ones here)

I am willing to try anything with swapping controllers etc, am also prepared to send someone an eeprom from a locked 760 (unknown Passord), and a locked 760 (Known password), to some people who can remember and use logic better than my old Uni days!!

Nick (Alsop), unlike IBM, I tend to think I have some Morals. I was thinking of sending you one of these locked drives, and letting you keep it in exchange for the password, that would enable me to unlock at least 6 more drives, and 5 TP 760 XL/XDs. I think that is kinda deceitful.

I have plenty of other locked drives etc here, perhaps we can come to a fair arrangement if/when you have the time.

Thank goodness for someone like you out there. I am thinking of that class action part....(has Family member that is LLb/Bsc (comp Science). But for now...just keep doin what you are doing..*ahhh the internet*

Oh finally....can someone give me some suggestions for looking at the area on the HDD that stores the I will lock a drive with a known password...unlock it, then go perving around in raw sectors etc?

The way to do it? (5:43pm EST Wed May 22 2002)
I belive the solution should be:

Read the context out of the eeprom, easiest way is by removing it. Run the dump you get from the eeprom in the cmospwd utility, which retrieves the password.
Re-insert the eeprom, and type in the now known password.

If this is not the way it should be done, please correct me.

Btw, if anyone has a dump from a TP600, or any other with a 24c01(a), please mail me a copy Thank you. - by Henke

Hard Drive Password (1:15pm EST Sun Jun 23 2002)
After reading all of the postings here I feel that I'm a little more informed than when I started, thanks everyone.

Here's my situation. I have a 380XD Thinkpad that has a supervisor password set that has also locked the HD. OK, what this all does is beyond me, I can still access the drive and the system boots fine. The problem is that the drive is going bad. I can still access the drive but the bad sectors are growing. Since I can access the drive is there any way to access the "hidden" sectors to obtain the password in order to unlock the bios so I can swap out the drive. I have a unlocked drive but when I install it I get a error number indicating that supr password is set and the drives is not and it immediatly prompts for the supr password to get in to BIOS, I'm assuming to make me set the HD password. Any help would be greatly appreciated, you can email me at or post suggestions here. I have used ddd to look at the drive but it does not access physical sector 0 where I believe this is held, it only goes to physical sector 1 (LBA sector 0).

Thanks in advance, - by Daveman

Nick Allsop - Hard Drive Unlocking (2:15pm EST Mon Aug 05 2002)
Unfortunately I am no longer offering a hard drive unlock service. This is due mainly to lack of available time but also the amount of spam mail and rubbish that I have been receiving since I offered the service. I have now frozen my Hotmail account.

A friend of mine may be taking on the HDD unlock hardware that I developed and offering an unlock service but this has not yet been decided for definite.

Apologies to those who have sent me IDENTITY.BIN files. The HDDSEC utility is still available on Joe's website as it can tell you if your drive is actually locked or not, but I will no longer be able to process the IDENTITY.BIN files.

Good luck!

Error Codes 161 and 163 (2:31pm EST Thu Aug 22 2002)
A ThinkPad has three user defined levels of password protection: Power On Password, Hard Disk Password, Supervisor Password. Your description indicates that your ThinkPad has an unknown Supervisor password.

Error code 161 indicates a dead backup battery error code 163 indicates the system's date and time is not set - clock is not updated. The date and time settings are located in the CMOS memory: error 161 and 163 appear because the systems CMOS memory was cleared (CMOS memory is cleared by removing the backup battery or by shorting Power On password pins/pads).

A ThinkPad Power On password also resides in the CMOS memory therefore, if the error codes appear - the CMOS memory was cleared and a possible Power On password was removed.

The above mentioned error codes can be easily resolved by resetting the BIOS settings. However, in order to access the BIOS settings (EZSetup), the Supervisor password must be entered. Although leaving the password field blank and simply pressing enter appears to bypass the Supervisor password prompt, the unit proceeds to the green error page with a manual icon because the Supervisor password is incorrect. If the Supervisor password was entered correctly, after selecting OK at the first green error page, the system would automatically access Easy Setup and immediately prompt the user to change the date and time.

A ThinkPad Supervisor password cannot be removed by Power On password removal techniques (clearing the CMOS memory).

Under normal circumstances, a Supervisor password will automatically activate the Hard Disk password. Proprietary hardware and software was developed that is capable of removing unknown ThinkPad Supervisor and Notebook hard disk passwords. Visit the web site listed below for details.

Thanks Nortek. Have you got a UK reseller?

The amusing thing is I set the passwords up to be "aston" for the supervisor and "villa" for the HDD. No-one else has used the machine.

Sucessfully remove Thinkpad 390x supervisor password (7:41am EST Mon Sep 09 2002)

I have sucessfully reset the supervisor password and changed it.
You don't have to pay any cents for it.
It seems not a "scientific way". But it works!

To do it, you just need a cable that is connected to ground. The grounded pin is SDA. In 390x, the pin is the most bottom left pin of ATMEL AT24RF08CN. You can connect to the ground through the metal body or the screw of your think pad. They are all grounded.

If you have another model of think pad, you can find information about the pin order from

When you turn on your computer, you need to connect and disconnect the cable several times. When you feel that the thinkpad is freezing, disconnect the cable and connect it again in very short period.
It's a little bit tricky.
But i believe you can do it. For the first time, i can do it on the second attempt.

You can access the harddrive at the first time. I don't know why the think pad didn't check the password of harddrive. But you need to back up all the data right away.
When you turn off the computer and turn it on again, the think pad will prompt you the hdd password. And you have to repeat the above process, if you want to be able to access your hd.

After the second boot, you can set a new supervisor password (if you want to).

For removing the password from the harddrive, i'm still working on it. I'll post it when i got it.

From my experience as a computer engineer, this way is safe. Connecting the data pin to the ground for a short time doesn't harm the logic component. But be careful with ESD (Electrostatic Discharge). You can remove ESD from your body by touching the metal of your computer by both hands. You can also use Anti Static spray to the device that you will use.

Good Luck.

IBM Travelstar DBCA-206480 HDD password (4:50am EST Fri Sep 13 2002)
Dear sirs,

I have few of these. Most are dead. But one has HDD PASSWORD. I tried to change electronics, but it did not helps. Tried to connect as secondary slave to normal PC through adapter, it does not helps. Just one thing I can understand
that password resides not only on electronics itself, but on platters. Is it useless, or I just I have to wait for some good idea of unlocking it in the future, even I have no IBM notebook, just stand alone HDD.

Man, I can’t thank you enough! I have the Think Pad 390X I bought on EBay. When I turned on the laptop the supervisor password would not allow the computer to boot. I tried your technique of shorting out the Atmel and it worked! Anyone with the 390X try these before you pay the $700 for a new system board. It does work and you have nothing to lose at that point anyways.

Connect cable to ground (9:30am EST Wed Sep 18 2002)
Solder a very long wire to the SDA pin on the Atmel chip. Take the other end of the wire into the garden and dig a big hole. Put the end of the cable into the hole and fill the hole with earth.

Then the cable is connected to ground.

It's very simple, I can't believe just how many complete lamers there are on this message board.

Don't mess with electronics / electricity unless you know what you are doing. Go out and learn electronics theory before posting stupid messages.

Hi David26,
Do you happen to know the password chip of a Thinkpad 755c? And where is it located in the mainboard? Thanks. - by Rick
Re: IBM Password chips (7:27pm EST Wed Sep 25 2002)
Hey Rick,
I'm not to familiar with the 755c thinkpads, but the password chips are usually made by Atmel and its written on the chip. Problem is , if you buy the chip from Atmel, you still need the IBM information for the chip from a good password chip. But anyway, for that old a thinkpad, your probably better off just getting another system board off ebay for like 10 bucks or buy the whole computer for 50 bucks. Good luck.

390x password on fix (2:54am EST Sat Oct 05 2002)
remove keyboard, look in upper left hand, you will see a chip with 8 pins
take a small flat head and short 1-2,
while shorting power on lap top,
then quickly(but carefully) short 5-5 and press f1 while still shorting.
Worked for me, put in Hard drive and screwed me up again.
Repeated the shorting process and successfully accessed again, then booted to floppies multiple times, and went into bios multple times. WORKS. Might have to try slight variation with timing but those pins do the job.
Now to vent, I could really get bitchy as hell right now. I would like to pay someone back for the pain, however as usual the victory over these pansies always feels better than mere mortal revenge. Now that took 4 hours. I'll get back with you when I get my hard drive unlocked. P.S. Anybody from IBM out there counting pennies, Well, I'm keeping my damn 700.00 And next time I buy a lap top I'll make sure I don't get any proprietary security shit. I've got my own Crypto.

Shorting SDA to GND (9:51am EST Sat Oct 12 2002)
I haven't visited here for a while, I read the 390X method of supervisor password by-pass [I don't believe it actually removes it, it can't, it fools the TP but only till next power cycle or maybe altogether if you corrupt the eeprom badly enough] and I sort of may agree that shorting the SDA pin to GND is harmless, well in the sense that it won't set anything on fire as it is only pulled up to VCC by a resistor and the output of the eeprom takes it close to GND durin normal operation. BUT [don't you just hate it there's always a BUT] it can and chances are IT WILL CORRUPT the data in THE EEPROM. That doesn't matter with a 390X as it does not perform any sort of CRC checks, but a 600E and later Think Pad models DO perform CRC checks, try that rough method on one of those and the next message you will see is BAD CRC1 or BAD CRC2 error, no amount of shorting will remove that error!

I was wondering why suddenly I am getting so much e-mail from people with CRC errors, I guess they did try the short SDA to GND method.

By the way if you have tried THE 390X METHOD and you are now seeing a BAD CRCx error, I do have a solution costing only $50US that does repair the CRC error and remove the Supervisor Password.

This one is for all those that still believe that there is a UNIVERSAL PASSWORD [and that Elvis is still alive], the Supervisor Password is set by a HUMAN, who is allowed to enter up to 7 letters or numerals, the HUMAN decides what to enter as the password, the Think Pad stores it in the eeprom if he can manage to type the same thing twice. There is NO universal password, it may seem like it when one person sets the same password on a quantity of machines, but not really. - by Joe in Australia

Download the software (about 50k)

Connect it (the interface you built kit 151) to a computer (via printer port)

connect the eeprom to the programmer

power up the programmer/reader

run the program (eeprom.exe)

press "r" Read the eeprom into buffer
press "s" Save buffer to file.

now look at the line ":10003000" this is where your password is.

Count 16 places after the :10003000.

In this example the first pair of characters starts with a "1E" which is scancode for the letter "a"

The next pair of characters is "30" which is scancode for the letter "b"

Hard Disk Password (3:45pm EST Mon Oct 21 2002)
Anyone know where Nick Allsop (from the UK) is? He unlocked a load of locked IBM IC25 drives for me a few months ago.

I've now got some more for him to do but he is not answering any emails at

If you're out there Nick, please send me email - you've got my address! Would be happy to pay more than $20 per drive if you can spare the time as the data is needed on some (like with the last four).

Password? (6:48am EST Fri Oct 25 2002)
model 760xl,

Reports 8611 error,

then locked symbol

is there a work aroud?

any help appreciated

- by alan
In reply (6:38am EST Sun Oct 27 2002)

8611= Keyboard error

Locked Symbol=means it has a Supervisor Password.

Still workin on it.

161/163 Is time/config error.

I assume you are holding down the f1 key at start up?

If after doing that, it asks for a password, enter it, set date/time.

If you don't know the password..Cmos has been reset with Supervisor Password set also.

Read above on how to obtain the password. - by Ads

You can't low level format a locked HD using an Amiga, dumbass. A locked HD does not allow read/write access to the data area. Have you actually *tried* doing this, or did you just want to post something for the hell of it?

Joe in Oz's Key Maker (5:11am EST Thu Nov 14 2002)
I have successfully built and used Joe in Oz's keymaker on a TP 600e to get the Supervisor & HDD password.

I got all the parts from Maplin's. I found the circuit board ok to build if you take your time and have a multimeter to hand.

I left the asset chip on the motherboard and had the wires soldered onto it by J & P Electronics Ltd
of Kidderminster.

For a very reasonable £16, Joe in Oz returned the passwords.
- by Joyfull & Triumphant
Joe in Oz's Key Maker (5:26am EST Thu Nov 14 2002)
A couple of tips.

I had a problem getting the 4700 ohm resistors as specified by Joe. In the end i had to use something called (I think)a SIL resistor, which seems to be a number of resistors in the same component.

The TP 600e doesn't need to be completely stripped - the keyboard has to come-off (there are 2 tabs halfway down each side which need gently pushing in). The processor bit needs to come off and also a board next to it that restricts access to the asset chip.Batteries need to come out.

Use insulated wires and makesure they lay flat as u have to replace the proccessor board ontop of them.

Radio Shack/Tandy do a great introduction to electronics book.

When removing screws push them thru a marked piece of paper to remember where they came from.

Get the IBM technical manual as specifed by Joe. - by Joyfull & Triumphant

If someone puts the effort in, like Joe, to build the site, links, software and component instructions the least you can do is pay him a fair price for his work.

You are an embarrassment to humanity.

- by J & T
Free thinking people (8:17am EST Thu Nov 21 2002)
J&T you are talking cr*p.

Joe has been quite happy to make money out of people who are unable to unlock their laptops, whether genuine owners or people who have stolen them. He has even gone to the trouble of 'encrypting' the output from his EEPROM reader software so that the average user has to pay him for the password.

No-one asked him to set up a website or sell his service. He could have simply asked for 'shareware' donations as many others do. The EEPROM reader he has 'designed' is hardly a innovative design, neither is the software he has written.

Let's face it, anyone with even a small amount of knowledge (plus the relevant datasheet from the chip manufacturer's website) can design a serial EEPROM reader/writer and it is common knowledge that IBM TPs 'encrypt' the BIOS password as standard IBM keycodes.

By trying to make a mystery of reading an EEPROM, and in return for hard cash, Joe has made himself a target for anyone who has the ability to 'hack' what he is doing. Just as is the case with any commercial business.

I would be more impressed if he had developed a solution for removing passwords from the actual hard drives - like Nick Allsop (UK) has (and Kaya from the Netherlands says he can).

Although these guys no doubt charge for their services, the technology involved to do this without deleting any of the stored data is far more complex than reading an EEPROM.

Sorry J&T but I don't see any problem with people using their initiative to avoid paying Joe or any other business their hard-earned money.

I welcome people who are free thinkers. Without them, human civilisation would never progress.

Talking cr*p? What do you do for a living David Wilson? When you've put the effort in for a day, are you more than happy if someone capitalizes on it without giving you reward? You work for free?

I love it when I've worked hard and someone takes the credit, passes the hard work off as their own or exploits my efforts to make money without paying me.

And how does the above make the world a better place and move it forward? The idea of doing stuff for free is great. And ideal for losing weight. And the roof over your head. Socialism isn't based on a 'free lunch' and inovation isn't encouraged because something is 'easy to do'.

HDD Password (1:57am EST Tue Dec 10 2002)
Only way to get access to locked HDD (a part of expensive equipment) is to boot from opened HDD and then "hot swap" it with another one (two HDD have to be absolutely the same: brand, size). Then using low level DOS utility (like NortonDiskEdit) try to find where password is located. Some BIOSes do not allow to swap HDD, simply do not recognize Hdd after swapping. This way is a bit risky, DO IT ON YOUR OWN RISK !!!

Maybe somebody has got "homemade" utilites to find password using this method ? Feel free mail to my new adress - by Frank from Germany

Thinkpad 770X Boot problem (9:08pm EST Tue Dec 31 2002)

although our problem doesn't fit exactly in the ongoin' thread, maybe
someone might have a clue what's goin' on.

Booting our TP 770X it started with an 173 163 Error, which is,
refering to the TP Maintanence Manual, a wrong or lost time date info.

Clicking OK in the error window brings up the Easy-Setup window for
date and time info. Well, entering the correct date and time, clicking
OK and the system hangs.

This also happens when clickin' on CANCEL in the error window.

Anyone having a clue what's goin' wrong?

Many thanks in advance.

BTW, happy New Year to all of you. :-))

PS: It's not a PW problem...

PPS: Refering to the TP Maintanence Manual I've already short circuited
the Jumper J13 on boot time, this should help to solve problems the POW.
But no luck in this case.

760XL super password (9:41am EST Wed Jan 08 2003)
I have an old locked 760XL. I have read the eeprom, however the password is not obvious. It seems other TP models store the password in scan codes at 0x38 and 0x40, however the data in my 760 at those locations is clearly not a password. Also, earlier in this thread there is a post of a 760 with a known password (1234567) and in that post, location 0x38 is not scan codes, which confirms my experience. So does anyone have any dumps from a 760xl with known passwords, so I can attempt to identify the pattern and extract my password? - by GJP

Unlocking Hard Drive Password (12:09pm EST Fri Jan 17 2003)
*** My fix was easy not to mention FREE! I also own a PowerMac G4. I recently bought an external firewire hard drive case. I put the TP Hard Drive in that case, connected via Firewire to the Mac and reformated the complete drive. When I put it back in the IBM there was no password required and it was 1 single partition instead of the two it used to be with one of them locked. So my suggestion is to find a friend with a Mac and let them format it.

1 remove screw under hard drive area.

2 Pull hard drive out then slide it back gently.

3 Push power button then gently move the drive in and out while listening to
the drive. you will hear it start to spin up to speed. Don't let it spin up
too long or it will display the lock.
If the lock appears start over.

4 If the drive cant boot properly in 20
seconds you will get a screen that

5 hit F1 or ESC to enter BIOS

6 remove or change any passes in BIOS

Replace hard drive and reload OS.

Thinkpad 600E help (7:07pm EST Mon Jan 27 2003)
I have an IBM Thinkpad 600E laptop with the traditional unknown supervisor password and locked hard drive problem. I traversed almost every internet site over a year without finding any easy solution for the non-technical person. Finally I decided to purchase a system board having resigned to the sad fact that the present board was not useful anymore. I thought why not experiment with the locked board so I grounded the SDA pin on the Atmel 24RF08BT chip and booted with password protected hard drive removed. Lo and Behold !! I was into the bios. I immediately changed the supervisor password and the system worked. I now booted the laptop with the hard drive (still password protected )and I got an error 158 (supervisor and hard drive passwords do not match). It took me to easy setup where I simply click “Exit” and upon restart the drive booted successfully. The problem is that this sequence continues with that particular hard drive. I was wondering whether the hard drive password, which is presumably still active, can be retrieved from the now seemingly accessible drive. I tried a few file recovery programs but I always get read access errors for block 0. Is there a way to access the password on that drive? If anyone can help me please email me at - by Mike

Update re: Thinkpad 600e help (11:12am EST Wed Jan 29 2003)
My previous post mentioned the grounding of the SDA pin on the security chip of the Thinkpad 600E whilst booting. Without a hard drive installed I was able to now remove the supervisor password from easy setup by simply following the User Reference Guide's procedure for password removal, so that, with a password -free hard drive installed the boot process is completely free of password requests. I have concluded that the password on the original hard drive cannot be easily removed. I will try one more procedure before giving up on that drive. An earlier post mentioned the hot plugging of the affected drive as secondary on a desktop (with related adapter, of course) after the system has been booted with a drive of the same model and size. I will attempt to do that when I acquire a drive. Be reminded that I grounded a chip on a system board I was about to discard. I will not recommend that anyone do this if that person is not prepared to risk the board’s demise - by Mike

Thinkpad 600x help (10:04pm EST Wed Feb 05 2003)
Regarding to the previous post on TP 600E help: I have a TP600x with supervisor passwd and hard disk passwd. It didn´t boot because a date error (161, 163), so i shortcut SDA and GND and it worked, it boot (the supervisor passwd was there yet, but I can run my win2k). But there was not all, as I managed to boot up the computer I thought that I would be able to delete the passwd so I did it again and the only thing I get was a 188 and 189 error!!! :(

So be careful, I can promise that it worked I have started windows and I can enter easy setup (I didn´t have access to all bios features) but then I corrupted all the bios and so the procedure doesn´t work any more (the eeprom is corrupt so there isn´t possible to enter bios)...

If someone has a bin of the 600x with no password I will try to reprogram the 24rf08, my hd will not work but at least I don´t have to throw the whole TP to the trash. - by Rodro

Why bother with all that shorting out stuff. Just unsolder the password chip and swap it out with one from a dead motherboard, if you have one, or buy one off ebay. Its a lot easier and a lot safer.

HD password on TP 380Z (3:58pm EST Thu Feb 13 2003)

I've an IBM TP 380Z which works perfectly with a Travelstar DADA-26480, 6Gb. I've another Travelstar, model DADA-24090, 4Gb which refuses to boot: The much hatred Lock/HD symbol,
indicating that it has a HD password. Although this is a 'spare' drive, I'd like to use it for another OS than WIN 98 SE which is on the 6Gb drive. Any suggestions ?

Thanks in advance,

unlock IBM Travelstar harddisk (8:56am EST Tue Feb 25 2003)
After all the mess & chaotic messages that came up here, there still isn't a sollution for unlocking a harddisk. Myself: an ibm t21 with a 20 gig harddisk (DJSA-220)

This one is locked. I removed all the BIOS password etc. By simply removing the CMOS battery. So when i remove the locked harddisk, i am able to get into the bios.

Thus, it's only the drive wich is locked. I tried to put the drive into a laptop wich don't support hdd-security features in the bios (such as old x86 and pentium 1 machines) Finally put the disk in a Toshiba 230 CX, boot and start Norton's Disk Editor. When a harddisk is locked, there is some information written in the first 512 bytes of sector 0. If you're able to replace them all to "00" then the lock should be gone.

Actually, i tried this and the result was an "129 error" message from DiskEditor.

So, if there is somebody who can do something with this information, please tell it.

In meanwhile i found somebody who can unlock most harddisks. But i like to know (and manyMANY people here to) if there excists a workaround for unlocking your harddisk. - by sector0

I can boot to CD is there any way of reading the eeprom through software means I.E. and software EEprom dump

it should be possible cause the bios has to be able to access the EEPROM to read/write and check the password

ATAPWD (10:46pm EST Sat Mar 15 2003)
I see a lot of talk about Passwords for Travelstar harddisks.

What has happened is that you have a "User" password set on the harddisk. If you search for a tool called "ATAPWD.ZIP" you can find it on Goggle, this will let you format the disk if you have the master password. However I have never found out any Master passwords for Travelstar disks.

Anyone work @ ibm and know how to find out what the master password is for a travelstar disk?

But for admins, ATAPWD is also very usefull since you can SET the master password and prevent password loss again in the future (since you can unlock a disk if you know the master password!)..

Wow seems to be allotting on this subject here well all I to am stuck with a TP 600e with the dang 161 163 errors.

I got mine by pulling the laptop apart to repair the power plug on the back of the unit (what a job I might add) well its all back in one peace and now I get the errors funny thing is there where no passwords set on this unit to start with so why I cant get into the bios is beyond me. One would think that if there was no passwords to begin with then there shouldn’t be any after you put it back together. I have tried most of the so called fixes on this page other then building the reader seeing I don't really think I could build one if I tried. But I do have a really large hammer that just might work (evil Laugh). Anyways anyone know if there is some sort of utility disk to clear the sup password if any because I can't IBM replacing the main boards just to clear a password or after repairing the laptop (I have noticed the floppy dose try to read before the system displays the error codes and then stops with the error codes and the little manual page)

IBM Thinkpad 390E Problem (9:31am EST Wed Apr 02 2003)
Do you have any suggestions or solutions . canyou send me this free ware as sson as possible i am in afix

I have an IBM 390E laptop . Now intially the problem was when you power-up the power-on password emerges. So at the time I thought it was a mulfunction because there was no set poer-on password set on the Thinkpad because the laptop could still boot by you press CRTL+ALT+DEL.

So I decided to upgrade the BIOS with the latest version I followed the instructions to the letter,except getting rid of the power-on password which was an error to me anyway. So after the BIOS upgrade it started up fine thrice so I left the laptop to the owner knowing it is fine.

No to my surprise the following day I was called ,being told that now it has any Icon of a HDD & a lock with a number one symbol which translates to HDD password one installed on the PC. Now my client is telling me that she didn't do a thinng like setting the Password and would rather I reverse the whole process. No I am in a fix because even the CRTL+ALT+DEL can not go through. Do you have an Idea of who can help and what should I do . now that you are having a similar Laptop like mine.

I thank you in advance and please forward my request to I don't have the email address. Thanks in advance. Can you help me and what do you think of this microwave stuff releasing alll password.

P/S can I try this hotswapp thing on my laptop please let me know



EmAIL: - by Joseph Oluoch
Re: IBM Thinkpad 390E Problem (1:13pm EST Thu Apr 03 2003)
Joseph - I would suggest that you contact a professional data recovery company if your client has important data on the hard drive. Messing about with hotswaps and other methods to remove passwords is fine if it's an old laptop that belongs to you, but if it is someone elses it's worth paying a professional to make sure the data is safe.

Try these guys, I have used them myself. Don't know where you are located but they have offices in the US and UK aswell as other countries:

Joe's Interface - Quick Question (11:56am EST Wed Apr 30 2003)
I'm nearly done making this thing, but i'm looking at the schematic and there is one thing i do not understand. Why is it that when looking at the 24RF08 EEPROM chip schematic, it says only three wires are supposed to be connected (SDA, SCL, and GRD), but yet it has the PROT, WP, and VCC pins wired as splices from the VCC cable?

Furthermore, am I supposed to splice the GND cable, and have the splice go to the GND pin, while the original wire continues to be connected to the VCC wire via the 0.1uF capacitor?

Also, the CLK wire going from the device to the EEPROM chip... do we actually do anything with that wire, or just leave it hanging there for no reason?

ALL of these just seem a bit unusual. I've tried to find the answer using pictures from his website, but they arn't much help.

IBM Dropped $ of supervisor password!! (10:32pm EST Tue May 13 2003)
Hi every one, after spending more than an hour reading this forum i began to get really fusterated. i couldnt believe that ibm would not offer any assistance to someone who would lost their password. for arguments sake i went out and bought a nice new ibm t23, i then put a SVP on the laptop. i called ibm and they said the regular BS that was said previously on the forum. when i sent it over to ibm they sent me a repair bill of 49.95 to only wipe out the SVP and restore all settings to their default. i hope this helps

Did you get some kind of warrenty on the laptop ahead of time, and if so, what kind? Perhaps they are only willing to do this within the first 90 days after the purchase of the laptop.

When you initially talked to them, did they give you a quote before you sent the laptop in?

Successfully Removed 390X Bios Password (2:17pm EST Tue Jun 03 2003)
I was locked out of my notebook after updating various device drivers from IBM's website. WARNING! Be very careful when installing the "Bios Update" file. All the other driver updates for Windows 98 (modem, monitor, etc.) works great.

Follow the instructions authored by "Ray of Bandung" very carefully. To reiterate, short the SDA pin of the Atmel prom which is located at the upper left corner of the system board. As you look down at the prom, the SDA is the bottom left pin.

I was able to perform this without soldering. You see, I had great sex yesterday afternoon. My body is calm and relax. I was able to apply a very steady hand. Anyway.

Many thanks Ray of Bandung. - by One Happy Puppy
Ibm Travelstar 30G From Ace Laptop (2:15pm EST Thu Jun 05 2003)
I got password protected Ibm Travelstar 30G HD from my friend who recently bought second-hand Acer laptop with this protected HD. He replaced HD to a new 20G HD and sell me above disk for 50 $CA.

I read all above posts relating those disks to IBM Tthinkpad laptops. But mine came from Acer. I experience the same problems as others and have no access to HD. I'v put it as a socond HD with adaptor on my desktop computer and tryed various low level format programs, but ALL of them report "can't access - drive password protected".

As you can understand I don't need the data on the HD, I wish just format it and use with 2.5" USB2 external box as a data transfer disk (I already have one, 20G IBM 2.5" HD working in mentioned USB2 external box with 42MByte/sec transfer rate and I very happy with). I don't intend even to boot from.

Again, I have nothing to do with IBM thinkpads, this HD comes from Acer TravelMate sub-notebook.

Have somebody idea how can I unlock this HD from the password?

RE: 760ED - OR HARD DISK password removal (6:15pm EST Wed Jun 18 2003)
If you can get a prompt, then I assume you can also run a floppy disk. If you can, then there may be a solution to the elusive HDD password. Assuming the password is actually written on the HDD somewhere, and not stored in the hardware in a chip or something, then here's the possible solution. A long while back, when buying a New Hard Drive, i got a disk along with it. This was back in the day, with Win 3.1.

The disk contained software that could COMPLETELY zero out EVERY SECTOR/ EVERY BLOCK of the HDD. I didn't think anything of it at the time, but this software (if it can be found) could DEFINATLY be used to clear out a HDD password (if stored on the HDD itself). My guess would be that a password would be stored at the very beginning of the disk, and it is possible (however unlikely) that you can zero out just the password with this software.

Let me know what all of you think about this idea. If you think it could work, i may actually make an effort to find the disk. - by Elusive

I have built Joe's Interface for use with my own ThinkPad, and have since sold that interface, as well as 4 others, to people via ebay, or directly through e-mail.

I charge $50 for the parts and labor, and $5 for shipping within US, more for other countries. It would cost you just as much to build the interface yourself, if not more. So i'm really offering a deal here. I guarentee you will get what you pay for.

Hard Disk Password (5:23am EST Fri Jun 27 2003)
The ATA compliant hard drive which supports security features (i.e. HDD password) stores the password (which can be up to 32 bytes long) in a HIDDEN area of the disk platters.

Therefore any utility that simply wipes or zeroes out sectors on the disk WILL NOT succeed in removing the password.

In fact when a drive is locked, no access (either read or write) to the DATA area of the platters is possible. In order to regain access to the DATA area, you need to send the ATA UNLOCK command along with the correct password to the drive on the ATA/IDE bus.

Therefore please do not be fooled into thinking that any disk cleaner utility or sector wipe utility will remove a password from an ATA security-locked drive. It will not.

Hardware viewpoint (5:12am EST Fri Aug 08 2003)
The drive its self reads the data on the drive to its controler then sets the operating mode(operate or locked)it should be possible to read this data With some sort of direct hardware connection. Alternitive to set controler to unlocked mode. In any case it is clear that this feature does not stop someone determined to recover data from a drive if prepared to hack the hardware. It can only frustrate users who dont have the time and money to spend. A real negitive value for most users!

interesting predicament (5:40pm EST Sat Aug 23 2003)
i have a tp600x with the 12G travelstar drive. i want to upgrade the drive, but don't know the supervisor passwd - i do have the pop, so that when i enter it, i have access to the drive as it stands right now. it is a failing drive, so if anyone knows how to get the passwd off the drive WHICH IS UNLOCKED, but w/out the hd passwd, that would be useful! not, since TPs have the supervisor and HD password identical, getting the passwd off the drive would make upgrading it simple cause i'd have the super passwd too.

please email info at

IBM Travelstars (6:11pm EST Thu Sep 18 2003)
There is a fix to remove the hdu lock off the hard drive. It simply involves installing the hdu into an Amiga computer. This machine doesnt conform to the ata specs which include freeze and hdlock, therefore you can wipe the disk with the amiga format prog and then reinstall it back to your laptop and rebuild it using xp etc.

superivisor password (6:31am EST Sat Nov 22 2003)
I did it the same way as ray of bandung
suggested and was able to set the time/date in bios afterwards. But the supervisor password seems still be there. If I go into the bios some options like password change and boot sequence are grayed out ... and I'm still asked for a password, whenn i press f1 to go into bios - but just hitting enter will do. So, I assume that by shorting sda just the bios is faked but the supervisor password remains in the chip. One advantage does this method have, you can work wiht the laptop if jou had to change the bios battery and then locked out doe to the
invalid time/date in the bios. I did it on a tp600. - by xxgman
supervisor password (7:02am EST Sat Nov 22 2003)
another thought: if the bios can read the security chip, a small program executed on that laptop, should be able to do it also, e.g. by using the same instuctions as the bios does during power up. This would help in cases, when the laptop is still operational but the supervisor password is unknown. - by xxgman

Some Help (3:14pm EST Tue Jan 13 2004)
Hi there, I have worked on 100's of thinkpads and I don't profess to know everything but here is some help.

On the Thinkpad 600 series the 16X errors simply transpire into needing a CMOS battery replacement.
One means you time and date need to be set, of course you set it, but it have no CMOS battery to 'save' the time.
So, you will set the time, reboot, it will say turn laptop off and on and then might act funky after that cause it needs a new CMOS battery.

As the the Thinkpad T series (thorn in my ass) the Supervisor password is stored in the EEPROM chip. To date, I know of no way to remove it, short of removing the chip and replacing it. A reader may assist you in this but I don't know for sure. There may be soldering involved also on certain models.

If your having problems with the T series just email me at and i'll do what I can to help you out and I'll send you a PDF with all of the error codes and the maintainence manual.

In return for my 1% of knowlege if someone knows how to reset the password on a T series email me and let me know.

P.S. Toshibas were beautiful. There is a loop back type connector that plugs into the LPT port and you turn the laptop on and it removes the password.

Go figure.

OK, I have an IBM hard drive with the password. I never had the original laptop to begin with. I have been trying to get rid of the password on this drive. I have some suggestions that I am unable to try since I don't have the hardware to do it.

1. Hook it up through a USB enclosure. I don't have one, but they are so cheap that I am going to get one and try it our. I will post my results.

2. Hook the hard drive to a macintosh system and low level format it. I don't know how mac BIOSes behave so there might be some headway to be made there.

POWER ON- PASSWORD (3:11pm EST Sun Feb 22 2004)

READ..... (4:51pm EST Wed Feb 25 2004)
Long time, no see......

There are 2 fundamental differences with IBM serial Eeproms (containing passwords)

One is a 16 bit 93cxx (760 series)
The others are 8 Bit Atmel 24C (most others)

You need an 8 bit reader, or a 16 bit reader, depending on which chip.


Dick Smith Electronics (In Australia) make a kit you can build for the Atmel Eeeproms, or from memory, I built one from Ponyprog Website.


For Dell CPIs etc, there is a backdoor password that Dell will supply if you fax them proof of purchase, your ID, a screenshot etc, it works, I have unlocked 2 Dell machines without turning a screw. Email Dell, and they will tell you exactly what you need to supply.

This Master PAssword Revision Code is set by SEcurity Set Password command with the master password. And this revision code field is returned in the identify device command word 92. The valid revision codes are 0001h to FFFEh. The default value of Master Password Revision Code is FFFEh. Values 0000h and FFFFh are reserved.

I got no idea what this means but I found it for the Travelstar 32GH/30GT/20GN hard disk drive specifications. I think you can use these codes to unlock or reset the passwords, I have more information on this email me with the subject TRAVELSTAR PASSWORD and I will send you the whole document (.pdf) or post on here asking for more information. It says if you use this however and high level security is set then you will NOT lose data, however if MAXIMUM security is set all data will be lost. - by mikey
Thinkpad password reset (7:22am EST Fri Mar 12 2004)
For a TP 600 , possibly others, Remove the main battery from the laptop & look for a pair of pins which can be jumpered or a mini switch in a small recess of the battery compartment. Jumper the pins or toggle the switch, reinstall battery, power on, remove battery remove jumper or toggle switch to original position & reinstall battery. Voila.

For hdd, install into a non-ibm laptop for unlimited password attempts as opposed to being locked out every 3 incorrect guesses. Look for signs of wear or dirty/clean keys on the ibm k/b, often narrows down the possible combinations as they are used every time the user boots. - by Try 1st b4 flaming
I KNOW ALL THE TRADE SECRETS (4:45am EST Mon Mar 15 2004)
Hey, mister IBM Employee. It's a little complicated, but here goes. To get the the supervisor password for any thinkpad past model 760, the procedure is as follows:

-first build a small component that connects to the serial port on two computers. (email me for the wiring diagram, it's simple)
-configure a seperate computer to recieve binary data though the serial port (best done in DOS or unix/linux)
-sauter a few circuits to the EEPROM chip on the mainboard (email me with your model number, or if you want it faster, find the wiring diagram and email that to me)
-after all the sautering is done on the board, connect the serial ports and start the TP, all of the EEPROM data will be sent through the serial port to the host 'puter.
-save the data recieved
-use a compiler to compile data as a basic text format file
-the password will be readilly apparent after looking through that file.

that's generally it, for more specific info, post back or email me here: - by undergroundprophet

Unlocking Hard Drive (7:20am EST Sat Apr 10 2004)
I read that you could hot-swap a pcb from an identical harddrive/firmware from an unlocked hard drive to a locked one after its checked and set as unlocked. I was wondering if you succesfully accesed the "locked" platters (hard drive) if you could just lock it with a knowen pass, swap boards back and unlock it with the new pass, would it overwrite the un-accesable area with a new pass??

If I get the chance to try, ill post back. - by C4

I am a very average lady with very average brain. I have an IBM laptop that I sent to the local computer shop and the guy who works there tried to take the password off for me. He got the old password off and now there is a new one there and he nor I can get in my laptop. What kind of password is it and what can I do to fix it? The password comes up right after you turn it on but before you see any other screen. It is a black screen with the password prompt in the upper left corner. There is a tiny lock under the prompt and once I type in the password now I get an X and access is denied to me. HELP !!!! - by Freaky Babe

Geez you guys... (11:40pm EST Thu May 06 2004)
I have a Dell Inspiron 2500 with a Hitachi drive. The laptop has arrived from someone who wishes to be able to use the machine for home use. The laptop was given to him, according to his story.

I managed to circumvent the BIOS password by using a BIOS password tool to fake the BIOS into thinking it had a checksum failure. That problem was solved, however I am now presented with a hard drive password that must be entered before the machine will boot. I'm still working on this problem. If I come up with a solution, I'll post it.

Some things to keep in mind.

1.) Nobody here is interested in your corporate advertising spam. If your company can recover a HDD password, yipee for you. It doesn't mean we should be besieged with "Pay me and I'll do it for you" spam instead of useful assistance.

2.) If you know how to do this but are foolishly believing it's a "trade secret" and withholding the information, then you're a sad, sad person. Knowledge is public and everyone deserves the right to know, not just you.

Hack HD password (3:11pm EST Sun May 09 2004)
HD Drives Locked - Any Software programmers out there?
I also have several desktop hd's that have a password on them. My system will allow me to boot from a floppy, then i can try to unlock them.

I was wondering if anyone can write a dos program, that would boot from the floppy (or cd), then try all the passwords and start from all 0's, then work it's way up and test them all? Write the last code to a txt file, then reboot. I believe the ATA spec states that after 5 tries, you cant put in any more passwords. I was able to do a and was able to try 5 more.
There seems to be several utilites that can either unlock it or see if it is locked, maybe all those can be pieced together?
I understand this would take a long time to test, but it's better than having a paperweight?
Maybe even boot from a CD, and write a txt file to a floppy or another fat drive?

Supervisor and HDD passwords (10:44pm EST Thu Jun 10 2004)
Wow what a long list.
First off thanks ray of brandburg. Using an exacto knife I was able to rest the flat of the blade against the case while touching and releasing the specified pin on that tiny little 24xxxx chip. 390e got very confused and sent me to the bios and let me remove the supervisor password. Gave me access to the HD on that boot but upon reboot the HD password is still set. Rather than risk any of ths hot swapping foolishness I just replaced the HD with a cheap used 10G. There was one post about shorting out a jumper in the battery compartment but no follow up messages. Anybody try this?

HDD Lock (9:03am EST Tue Jul 06 2004)
You must be a moron if you think the Xbox will unlock a locked laptop hdd. You posted as if you have done it successfully, but I know you could not have. When you do a BACKUP in evox, it stores the hdd password(in hddinfo.txt) specific to that Xbox(generates it from eeprom data). It does not read the password from the locked hdd. - by TRoN
HDD lock (11:24am EST Tue Jul 06 2004)
TRoN is right. There really are no simple solutions to removing HDD passwords from drives. Sticking the drive in an Amiga or Xbox or for that matter through a converter on a PC ATA bus is just not enough. A locked HDD does not allow access to any data sectors and so trying to format the drive using ANY method will fail. To unlock a drive, some knowledge of the internal design methodologies of the drive is required. I work for a well known drive manufacturer and I speak the truth. - by Kelly M.

HDD lock (12:54pm EST Wed Jul 07 2004)
You are right that there is a way to do almost anything, but there really is no software utility that can unlock these drives because it is not possible through the ATA interface.

However it can be done using fairly complex hardware which connects to parts of the drive electronics. You need to know quite a bit of low level stuff about HDDs to do this.

I know of one guy who has built hardware that can unlock HDDs. He has posted elsewhere in this thread (Nick Allsop). I don't know if he's still doing it but it might be worth sending him an email if you are desperate.

I have directed a couple of people to him in the past and he was able to unlock their drives but I think he does charge something for his time & you have to send the drive to him.

Unlock Hitachi HD (3:04pm EST Sun Jul 18 2004)
Hi there I have a tip 4 all the hard disk passwords. Just put the Laptop HD in a Desktop PC as a slave drive and make a bootable dos disk.
1:Try to format the disk.
Or:2 On that dos disk you need to install a tool named "ATAPWD.exe" you can find it with With this tool you can hack the HD's firmware and discover the passw.Put the disk nack un youre laptop and boot it.

Good luck - by Benny D
Benny D hdd password (7:39am EST Mon Jul 19 2004)
Hi Benny D
i thought "ATAPWD.exe" only checks the state of the harddisk security and if you have the password already you can change it using that utility
but how do you hack the firmware using it i'm unsure
any help on where i am going wrong would be appreciated - by DaiBoy
ATAPWD.exe (12:07pm EST Mon Jul 19 2004)
I have an acer notebook that has this same issue. The only way i can get a floppy or cd to boot is to hotswap the hdd in AFTER post. I tried using ATAPWD and it does only show you the status of the drive. It does not allow any access other than that. None of its features work. The security on these drives relies on NOT allowing any access to the platters at all. SO you can not read or write to them in any way. I have tried a truckload of different utilities over the past month. IBM's harddrive software does go one step further than any of the others though. It will tell you whether or not your hdd lock is high or maximum security. Apparently a maximum security lock is unpassable, even by the recovery companies. This is a very secure measure of protection. I must say i am impressed at the same time as being frustrated as hell!! Good luck to us is all i can say! - by Alp22
HDD password (12:37pm EST Fri Jul 23 2004)
What an absolute load of rubbish is talked on this message board.

1) ATAPWD.EXE is a utility which allows one to view the security status of a drive and unlock it IF THE PASSWORD IS KNOWN. It cannot unlock a drive if you don't know the password.

2) Hacking the drive's firmware is a possibility, but not using some simple toy like ATAPWD.EXE, and in any case the password is stored in a reserved area of the disk surface. You'd have to rewrite the firmware to read the reserved area to give you the password. Not a simple job, and way out of the ability of the humble user.

3) Recovery companies CAN unlock drives that are locked with MAXIMUM security level. Read the ATA standard, this simply means that the MASTER password cannot be used to unlock the drive if the USER password is unknown, however the MASTER password CAN be used to erase and lock the drive.

If you have a drive that is locked, forget this nonsense. Either learn about how hard drives work and develop your own hardware to do this or buy a new one.

HDD Password (5:53pm EST Wed Jul 28 2004)
connecting to the hdd directly through custom hardware is the harder road to take imo. Brute hacking the password would be easier... so... can any programmer change the ATAPWD.EXE program (i suppose it would give unlimited password attempts?) so that it would simply brute hack the password?

if im wrong and the time needed for a brute hack is too long then im also waiting for a better answer :/

Brute force hdd password (8:57am EST Fri Jul 30 2004)
Assuming password is 6 characters and you only use numbers and letters, the total number of possibilities would be 36^6=2,176,782,336. 7 characters would be 78 billion. I beleive the firmware of the hdd(not the unlocking app) only allows 3 attempts, then you must power on/off(or reset?) to make another 3 attempts. - by TRoN

Easier way to get to EEPROM? (3:53am EST Sat Aug 21 2004)
There seems to be an easier way to see information stored on the EEPROM chip:
(You must be able to at least get into Easy-Setup to do this, so you'll at least need to know the POP)
As someone else had suggested, pressing Ctrl+D while in the Config section of Easy-Setup brings you to a manual BIOS editor. Cycle through the screens with F7/F8 until you see one which says "Base 64x2 EEPROM." I can see that this screen contains two serial numbers and the model number in plaintext, and two other lines of seven characters that I suspected to be passwords. However, those two lines as they appear do not work as the supervisor password. Does anyone know if the Thinkpad 770e 24c01 EEPROM encrypts passwords and if so, how to decipher them (preferrably for free?) - by frustrated but hopef

All you people posting crap about removing Power-on passwords, and the techniques available on the net, there's no JUMPERPADS 315 any where withing a range of 5 miles on the board of a Thinkpad. darn.
Ok, solution. We're fixing these systems. And we aint tellin HOW. Yeah SELFiSH or what ever else fish we're doing it. Atleast, we'll get your TP running, Supervisor and Power-on Password removal. Just plug in a new drive and get going. Long story short. People, please dont brag about HDD passwords throw the drive away get a new one. Cause by the time you've tried a million times to clear the passes on your own, turning the system on and off over and over, the drives get bad sectors already.
For the time being we're contenting our experties to ThinkPads, but some other makes and models are also dumb enough to be recovered.
So, what ever Laptop you got send it in, what ever make, company, model, TP's prefered as we're doing them the most.

You dont have to pay us any thing, yep, no charges upon arrival. You only have to pay us the Return courier. Or visit us if you feel like it. Keep your hard drives and battery packs/adapters, they add weight. Add the hard drive ONLY if you are dumb enough, not being able to remove a stupid HDD pass on your own.

Please add user/service manual if it came along with your laptop, other than IBM.

This is the cheapest solution available people since IBM's customer service is too damn expensive.

Other systems with broken, or faulty TFT screens, we can replace them as well, almost at cheapest rates. Contact through e-mail, for address and further information.

We're located in KARACHI, PAKISTAN

Hello (5:51pm EST Thu Sep 16 2004)
I am interested in developing an ATA brute force password cracker. I realize that this is less efficient/reliable than the hardware solution, but much cheaper, and you can do it from the comfort of your own home :-).

If the character domain for an ATA password consists of A-Z and 0-9, the number of characters in the domain is 26 + 10 = 36. If there can be 7 letters in the HD password, then the number of possible password combinations is 36^7, or 78,364,164,096. I assume there are people out there willing to wait for the computer to reboot inbetween retries, and with a simple bootable CD and floppy, and use of a utility that tris to unlock the password, this CAN be accomplished. Someone else posted a request for this, and I am willing to develop it. Any takers? - by WSWarez

With help of M. Ray of Bandung (see Sucessfully remove Thinkpad 390x supervisor password (7:41am EST Mon Sep 09 2002)by Ray of Bandung) above, I can use 3 years after very hard try my 770E.
The phenomena is 161 163 error.
Because CR2025 is out of order, 770E requet a supervisor pass to set clock. and block just after.
Try solution of Ray of Bandung, it work !!!
Ok, it don't work at first time, but after ~45mn, I arrived.
I've a screen to set the clock, reboot, retry, etc, but now it completely ok !

Ok, you have to dissasemble completely your laptop, but use book from IBM to do it with secure way (You can found in use this site also to see where is EEprom.

Thank you Ray - by DDOVIS
Different approach (4:53am EST Fri Oct 01 2004)
I have the POP for a TP 770 and can boot from hard disk or floppy, but cannot access BIOS without the Supervisor password. I have read all the EEPROM based solutions on this thread, but given that I don't want to rip the machine open, solder sensitive parts, and risk ruining it altogether, I've decided to look in a different place. Information on several sites states that if a Supervisor password is set but not an HDD password, the machine sets the Supervisor password as the HDD password and writes it somewhere to the disk. I clearly remember setting only the Super and POP passwords, so does anyone know a good hex-viewer type tool that can read the hidden area of the disk the password is written to? Someone else on the thread claimed to have done this but didn't say anything about the program they used. - by More frustrated, sti

The same problem with my A20p. Is there anyone ever successfully remove the supervisor password on A20p? I just don't want to replace the whole mainboard. Lucky my hdd is not pwd protected...
Any suggestion? Thanks a lot! - by leo

Never trust a company based in Pakistan. For all you know, you could be donating your machines to terrorism. Only a complete and utter fool would mail a computer to some shady Pakistan "computer" company hoping it would be repaired. You'd be much better off mailing it to an American, European, or Canadian data recovery center instead. At least you'll get it back. Unlike Mr. McIntyre who appears to have inadvertently aided the "glorious jihad" against the known civilized world. - by Amused

look this... (11:01pm EST Sun Oct 24 2004)
This password system does not prevent theft because:
When stealing a laptop, either off a park bench, while slipping into an office, breaking into a home or car a thief will not pull out their handy 'list of laptop models that are protected by an irremovable password", and leave the notebook there.
Thieves steal according to opportunity, and even if they are aware that a laptop might be protected by a password, they will likely steal it anyway. If they can't break the password, they can just throw it away, as it did not cost them anything, and has no investment value to them.
It also does not increase the likelihood of catching thieves, or the return of a stolen laptop because:
Stolen laptops are often stolen along with other belongings which could likely include the original owner's identity and/or paperwork regarding the laptop.
A thief who finds that the laptop they have stolen is protected by a password will not feel remorseful at this barrier, and seek out the legitimate owner so that they can return it.
If a thief should call Dell and be unable to provide ownership information and the technician logs their caller ID, and reports it to the authorities:
This is hardly grounds for a search warrant.
By the time any action might be taken by police the thief will likely have given up on the laptop and gotten rid of it, or passed it along to someone else. There will be no evidence, and no returned laptop.
If authorities confiscate a laptop which they believe is stolen:
They may or may not be aware of their ability to find the owner through Dell.
The owner may never have registered.
They may not initially be believed by Dell tech support and decide not to press the matter.
It also does not prevent the data on the laptop from being accessed because:
Anyone who has the laptop in their possession can remove the hard drive in about 10 seconds, put it in another laptop or computer (or copy it to another hard drive) and access it.

password recovery for ibm t20 (10:23am EST Tue Nov 16 2004)

Hi, Nice to see the great non-profit work being undertaken here.

I have a small problem. I purchased an IBM T20 from a workplace clearout (upgrades to company machines). Ive left the company and my machine has a hdd password. The above comments seem to be for other IBM machines. Is there any reasonable way of removing or bypassing the hdd password for an ibm t20??. Any help would be greatly appreciated as it would save me IBMS costly route and also make my machine usable.

MY IBM paswords (3:45am EST Wed Nov 17 2004)
I woulds still like to open my IBM IN ernast, But this page convinced me that IBM has the Hook up on all paswords that should make them very proude considering they are a light year back in technologyand want more too unlock a set than its overall value. Since all we do with older set is to give them to children with leaarning disoders FOC. IBM Even makes passing on the old computoer to student with a cause and those too haddicapped to operate a un-modified one. Even the aptiva is a near impossible set to work on as it has a handy dandy multi power level power suppy that usually fits at the top of the power supply bins of dead power supplies - by 3deng

I purchased an IBM Thinkpad 770X from the wonderful world of eBay only to find out it was all locked up. I was not about to spend any money on it so I decided to use it as a learning tool. I tried all the tricks mentioned here and everywhere I looked. Finaly decided... the hell with it. But instead of smashing it or throwing it away, decided to open it up and see it's guts. In the process of doing so, discovered that there is another NiMH battery inside the unit. I think that maybe this is the trick. I tried reassembeling the unit again but couldn't, as I was not carefull in disassembeling it. But may someone can try disconecting and reconecting it. I think it is this simple. It has a label with PIN 05K4652. If anyone tries this ant it works, let me and everyone know. Good luck. - by Flustered

Reset the bois password (3:11am EST Sun Mar 20 2005)

Go here to reset the bios password,
Remove the Hard Drive and put in a ordinary boot disk.
Power off the laptop short the two "Password Pads" they speak of on page 106 of the pdf file. Keep the Pads shorted and power on the Laptop when you power it back on for a few seconds. Let it go, reboot, and bam you got pass that one. At least that worked for me. I can't stand these jokers in here trying to make money on this.
As far as the Hard Drive one, I don't know that one. Get another Hard drive, or they're probaly things you can try to wipe it clean for a low level format. They are also a cheap tool you can buy to connect a 2.5" hard drive to a Regular IDE PC drive.

Good Luck - by Big Cliff

what a lot of shit posted here ...

yesterday i disassemble a hp omnibook 6100 a 24c08 eeprom is in it.

currently i didn't find out how to decrypt the pw, it isn't any scancode nor ascii, i found out that on 0x7F there is a "bitmap" where all passwords things are set.

convert the value to binary
0000 0000 => all passwords disable, hdd lock on

0100 0000 => master password enabled

0000 0001 => boot password enabled all other disabled.

0010 0000 => user password

some values (boot enabled while no password is set) didn't make sense, but still work.
i disable all pws and set a user pw, read the eeprom and copy the "xxx" hex pw-values to the userpw location on the originally eeprom.

==> i overwrite the userpw, but didnt know any master pw !!

when i boot the hdd (ibm) is connected and no error at all, i can use the whole disk, but didn't know the master pw.

when i disable the masterpw (using the flag) the hdd wouldn't work :-(

so i cannot unlock the hdd until i found out how hp crypt the password inside, but still working on it.

i think the hh lock flag inside of 0x7F is (000 1000) and i think it is inverted (making some tests, but not sure)

the passowrds are at the folling locations:
user pw: 0x5b - 0x63
master/hdd: 0x6d-0x75

i read something about hdd locking and ata specs, is it right that the password on the hdd is a 32 bYTE value?
is it a hash of the masterpassword or something?

the result of my "meditation" is, when its possible to disable/change the user password and test it how they encrypt the data, maybe its possible to "test" a couple of letters and numbers to find out the masterpassword and then unlock the hdd. maybe its simply bitshifting or something...

at the end:
atapwd is a nice tool, to see what sec feature is enabled, but still useless without any passwords.

b.) buy a new hdd.

IBM R40 Security Chip P1 (6:04pm EST Sat Apr 02 2005)
Let me tell you a little story about how I came aware of these little pains in the a$$. I recently got me new laptop and me first laptop at that, its a IBM R40 2681-CU3. I obtained this little jew for a small fee of $300 at a pawn shop with windows xp home preinstalled. Well I hate xp home so I was going to go and put a pro version on then set it up the way I wanted it set up not to mention it had a few error when it booted up like all old instalations of xp have. First thing was to set the bios to boot of the cd-rom drive and there it was... The supervisior password was required to gain access to those settings. Being honest and all I called IBM and asked how abouts to remove or clear the password told them where I purchased it and every other little detail they asked for, including the windows key (why I dont know but they did). Any how the tech person (so called twit) she precedes to tell me that I could try removing the cmos battery and the battery pack as well as the cord for a few minutes to see if that will clear the bios password. So I hung up and did as she said to the T even tried it 3 more times for GP. Well all it did was lock the PC up tighter then a nuns c_nt. Now I cant even get into windows it now has a pop password. Well I called back and Im not 100% shure but I believe it was the same gal (at least it sounded like her) and told what I was told. She then preceded to to tell me that that is a shure fire way to reenable the supervisiors passowrd for the bios and for boot up. And then she telles me "there is no way to remove, clear, reset, recover, or even change the security chip on the board. That in fact I would have to buy a new board and I might as well buy a new pc for that cost. Well to say the least now I was pretty F_____G pi$$ed off to say the least. - by Just a Kid
IBM R40 Security Chip P2 (6:06pm EST Sat Apr 02 2005)
But not to be one that gives up easy I did a bit of thinking and a bit of searching as well. After talking to some great friends that I have aquired on web over the years that are verry good and also unliked reverse engineers I came to a possible solution. There is place called password crackers on the web and they offer for $100 a new security chip to replace the one that has a password on it. Well after calling them they would not tell me where the chip was at since I didnt purchase one. But since Iam one that has a hard time to quit I went ahead and purchased one for thier price and with a thought in the back of me mind ticking away. So I waited to get the chip and when it arived I replaced the little bugger with the new one. Oh by the way.. its labeled as U24 on the board and believe it or not dumb a$$ IBM painted the thing green so it realy sticks out one you have an idea as to where to look for it (just south of the hhd). So now since I get this new chip in place and run a search for the chip on the web I goto find out I can buy one of these little jewls for about $3.20 a piece. hmmm ALOT LESS then the $600+ that f_cking IBM wanted for a whole new mother board that was the only way to regain use of the laptop. Well I also found that if you want to read what is in this little atmel chip, well get your self a an older Dishnet reciever with a jtag port on the bottom, a free ware program called JKeys and a hex editor like WinHex. - by Just a Kid
IBM R40 Security Chip P3 (6:09pm EST Sat Apr 02 2005)
Well just note the pin 1 location place your locked chip on the board of the reciever in place of its eeprom, edit the details in the .def file of JKeys for your eeprom that has 8 legs, and then read the eeprom save to file and open with winhex.Now what does all this cost you?? Well if your brave and can think OUT SIDE OF THE BOX, then you can get the software for free even trial versions work since the eeprom file is only 8k and reciever well you may even find one at the dump just make shure you got a JTAG port on the bottom and 5 100 ohm resistors for makeing your own jtag cable you connect to the parrell port of your PC.

I Tell you all this for one simple reason.. IBM is f_cking scum!! they are nothing but money hungry leaches that live off your neglect to think out side of the box. Thats right I hope IBM hate my ass for this and I hope they get ripped for selling abunch of stuff that is unneeded. For instance is it right for you to have to buy a new laptop cause your hard drive takes a dump?? Why not only thier hard drives work in thier laptops and you can change hdd from one machine to another. BS. Thats all I got to say. Oh yeah want all the maintence manuals they got for your laptop then here go. Since I cant say EXACTLY where to get them I can tell you this LOL. Think out side the box. Now the link is in this thread allready on a manual, so... remove the file name and a couple of directories and there is the FTP that has it all for most of the laptops in fact gigs and gigs of data, manuals, drivers, service notes, publications and so so so much more. But wait if you visit the FTp in explorer you cant see that much... they must be hidden server side. So get a small app like flashget that rips all files on a page... and there you go so many gigs that most dont have enough HDD space to get it all. Look for the index files and the allfiles files to see what the files are . - by Just a Kid
IBM R40 Security Chip P4 (6:10pm EST Sat Apr 02 2005)
Open them in notepad and do a search for what your looking for then get it while you can. Oh yeah to be legal and all for all those out there that have bone to pick with some one like me.. well if you use a FTP clinet you will see that there is a notice that the ftp is not for every one, but hey they dont password protect all the folders and it is freely accessed so uck you IBM! And your so called trade secreats shove those up you butt as well! :P Now for those that want to make some money at this or even do it for your friends here is an idea.... Use the above methode for reading and eeprom copy the data from one you buy for $100 and then copy the data to a new $3.20 chip and sell it for $75.Hmmmm is it trademarked and or steeling the info. NO Why? Cause IBM cant copyright a simple chain of chain of commands in a eeprom. This is your LAPTOP not thiers! They cannot tell you that you can not explore the contents of the chip. Now if you duplicate the chip physicaly that would be different but of course we cant do that so no need to get panties in not. Were all here to share info and this is what I found out in a matter of 3 days and some time looking and not giving up. But most of all THINK OUT SIDE OF THE BOX. If you found this thread you can do the rest. Oh one other thing all the data is in hex code and mose hex code has a common set of op codes for atmel stuff not mentioning you can get a free AVR studio from atmels site as well that has ll that stuff ready to go in it for you.

So one last thank you to IBM and thier screwed up tech support, I hope you choke and die!

- check status: atapwd or in linux hdparm -I /dev/hd?
- haven't check the tools from the xbox people but doubt that they can remove the pw if it is an arbritrary one. Thing is, the pw is in a system area in the platters , where the firmware resides. This is not accessible with the regular ATA commands. You would have to know the propper command s to interact with this firmware area and these are dif for every maker and even between models. So frezzing, formating with mac or amiga dont work - the locked state is internal to the drive regardless of what you do outside to the box or the OS. Various data recovery shops have adquired this knowledge for some models.
- If you want to program a brute force crack it is easy check the ATA standard, use DOS to keep it simple and reset after every 5 attempts (power off hdd or reset line) which you could automate by making a symple cct attached to line #1 (^RESET) to drive it low by sending a signal from the parallel port. It will take forever on average still.
- and here comes the spoiler: in a pinch, and if you don't care if you lose the data, the drive, or your motherboard and if you have the identical drive unlocked (same model, same firmware version: check with hdparm -I ) do a real "caliente" transfer :-) it may just work for you or it may not, in which case it's professional care for your drive, if the data is that important - by Eric Cartman

Most crc errors in the bios are repaired by updating the bios, how ever if the machine will not boot up even off a floppy then you may need to aquire a preloaded bios chip with the current bios if it is removable. There also may be a fix in the maintence manual for that laptop. There is a FTP talked about above in a post by "Just a Kid" that I know works since I have been there but you will need to look for the all files.txt files to see what file is the maintence file for your laptop. Good luck and hope this helps. - by anobody
