I was looking around at some of he good advice here on the forums, and decided to search for an issue I have with two identical laptops. I was not able to find this issue, though some posts did come close, so I thought I would throw it out there and see what everyone thinks.
I have had these ThinkPad T41 Pentium-M for about 3 years with XP, but over the last 12 months I have had this growing issue; the whole laptop, except the power button, stops responding. It doesn't just freeze, the picture jumps a few pixels over, goes fuzzy, then goes black all within a second. When the picture comes back, it is still fuzzy, but nothing responds, nor do the drives work. The only things that work are the cooling fan, indicator lights, the screen, and the power button. If I turn off the computer (holding power for 4+ seconds) and try to turn it on, the fan comes on and nothing happens. Both laptops are doing this now.
This started about 6 months before, but it was not so severe. When this started, it was a flicker but the computer would still work. Then it started doing the picture jump thing then I had a 50/50 chance of it still working. Finally it was doing the screen jump thing and just freezing.
At this time I noticed the time frame from start up to freeze was shortening. In the beginning, I was able to use the computer for hours before I had the issue. As things got worse, the longevity decreased. It is now at a point where I can get about 5 minutes from dead cold start to computer freezing.
One computer was used for work and was left on for extended periods of time (up to and exceeding 24 hours with about 10-14 hours of use followed by hibernation periods). The other laptop was used casually for home use and entertainment. It was used for 1-4 hours every or every other day.
The fans are free of obstructions, but the laptops used to get pretty hot. Heat does not seem to cause the freeze-up issue, as when they shut down now they are no more than slightly warm.
What do you think might be happening? What do you think is causing this issue? Any other information might help you?
