Hello. At last, I figured out what is the problem in my 701c with suspend/resume. Yes, it is a hardware problem. The suspend/resume works fine on small OS's such as DOS, 701's setup program. So, I suspected the extended memory. I took 16mb memory out. Sigh, everything works fine. I had a hard time with NT 4.0 in 8mb space. (Mine is 8mb(system) + 16mb(extended)) Gosh, I bought this used 701 recently. The seller repeated that the machine is in an excellent condition and he didn't know about the suspend problem because he didn't use it. Well, should I believe him ? Does it sound resonable not to use a suspend/resume function on a notebook PC ? Anyway, now I know the problem. Many thanks to all the guys who helped me. Going back to the hardware problem, maybe the 16mb SO-DIMM is defective or incompatible. I found it is not a IBM thing. It says 'Southland Micro Systems'. The model number seems to be '28720-70V'. The memory chip is from Mitsubishi, and labeled 'M5M416400BTP, 4482D02-7'. Does anyone have a problem with this kind of third party memory upgrade ? One happy possibility will be that the memory is OK but the motherboard does not supply a proper power to the memory. Then, I can go to IBM service. I hope this case. Would you tell me about your case with the memory upgrade ? Thanks. ------------------------------------------------- Dr. Myoung-Jun Kim, U of Washington BOX 352650 Seattle WA 98195 On Mon, 3 Feb 1997, Myoung-Jun Kim wrote: > Thanks very much for all the replies.
