Computer stalls under 100% cpu AND use

[JSabou1]

I run folding@home constantly on my T60p, which makes it 100% cpu all the time.

What is curious is that my laptop freezes if I use the mouse (trackpoint of touchpad). If i leave it on it with it at 100% cpu it doesn't freeze, nor when I am not running F@H and using it.

Typically, I use the mouse a little, then the temp of the cpu goes from 95 to 86 (I would guess because the frequency goes from 2161 to 1662 MHz) then it freezes right after. By freeze I mean the screen looks exactly the same as the last moment, and all processes seem to stop as the fan speed goes down.

I thought this would be a temperature problem but if it was it would either shut down the computer. But it doesn't it either downclocks and freezes or just downclock until it cools off, then go back to full frequency.

I also thought this could be because of gpu heat from the cpu, but I don't think it could be that because I watch 720p video while folding, and if I don't touch the mouse, no problems.

It seems to be induced by the keyboard, and I need to replace it anyways, as my W, A, and D keys are faulty from overheating and long use.


I was wondering if you've ever heard of these problems before and any possible fixes? Not expecting any magic work here, but yeah, previous exerience is not helping me on this problem

Thanks!

Does this occur with an external keyboard and mouse attached?

Nope, with regular keyboard and the trackpoint and touchpad provided.

I don't know what this means. Does it occur with an externally attached keyboard and mouse. Yes or no?

[JSabou1]

Sorry, just noticed how I evaded the question.

No, it is the laptops internal keyboard. I don't use external mice either. I use the track point and touchpad.

Yes, I understand, but what I am recommending is that you try to attach an external USB keyboard and mouse to see if the problem also occurs while using those peripherals. The answer to that question would point to either a hardware or software problem.

Hmmm will do asap, although it isn't science and can't be replicated with a specific instructions, I'll try and post asap.

Sorry, been offline for a long time. This doesn't really apply to me anymore. I got a new laptop and I'm just going to use this one for folding@home. So since I won't be using the mouse anymore no real reason to fix it.

Thanks for your help.
