Password Override for Thinkpads



Here's how to override the poweron password as stated in the Hardware 
Maintenance Manual.  Maybe this should be added to the FAQ.

Models 750x:
1. Power off the computer.
2. Open the Keyboard and remove the batter pack and the diskette drive.
3. Lift open the small panel on the very left side of where the diskette 
drive was.  To the left of the two backup battery connectors should be an 
open connector.  Install a jumper on this connector.
4. Reinstall the floppy drive and battery pack and turn on the computer.  
Wait until the Power on self test ends.  The password is now erased from 
memory.
5. Remove the jumper in the same manner as before.  You cannot set a new 
password until the jumper is removed.

Models 355x, 360x, 755x (except 755ce, 755cse, and 755cd):
1. Same as for the the model 750 except the small panel below the floppy 
drive has a screw holding it down instead of being snapped in place.

Models 755ce, cd, and cse:
1. The Password override connector is located just to the left of the 
battery pack terminals (the big battery not the small backup and 
standby batteries).  On the CD model you must remove the CDROM 
drive to access the connector.  Otherwise same as for the other models.

This is from the Hardware Maintenance Manual Volume 2: Thinkpad 
Computers, part number S82G-1502-02, 693 pages, about $18 from IBM 
publications.

It also has the password override methods for the thinkpad 300, 500, 510, 
700, 710T, and 720.
