T43p freezes due to overheating?

[dinotopia]

Hi, my T43p 2668-G7U has lately been freezing up periodically. All of a sudden, the machine will stop responding to the mouse and keyboard.

This generally happens when the computer is being stressed - running things like ArcGIS and the World Community Grid Agent (distributed computing) at the same time. I also don't turn the machine off, I let it crunch the distributed computing project all night long.

But I don't think it's entirely a problem of how I use the machine. When I don't run anything, the temperature will creep up steadily. I have the fan set to turn on at 55 deg., and even when I let the machine power down and cool off, within minutes the fan turns on. The machine reaches 55 deg. really easily, and when it's stressed, I've seen it go almost to 80 deg. I haven't called tech support yet, though if this continues, I won't have a choice. Is my machine just an unsually hot one, and is this freezing caused by overheating?

Have you measured or made a log of the temperatures right before the system freezes? I would do that and see if this can be reliably reproduced with those some conditions met. The only other things I can think of at the moment are bad memory or not enough causing alot of swap space to be used and many of the CPU cycles devoted to managed the abstracted flow rather than anything the program demanded in particular. Try looking at how many HDD I/O Operations go on as well. How much memory do you have in it? HTH

Hi,

use fan control utility and set manual speed to 127

my system newer crash with this settings

IBM support center can solve this problem... but i don't have time to send my t43p and im not sure, this is only info from ibm.
