Since some recent changes, my machine suddenly powers off at random times. I suspect it's overheating. I've installed a temperature monitoring utility to watch how hot the CPU gets. Maybe I will be lucky and happen to glance at it sometime right before the next crash, but it's much more likely I'll forget, or it'll be covered by some major app's window.
Is there a way to know, without actually having the computer overheat and crash, what the threshold temperature is? Maybe it's hardcoded in some place deep, and is the same for all brands of laptops? Can it be altered?
I'm running Ubuntu 10.10 and am watching temperatures of my Intel T5550 with acpitail. The machine is a Gateway P6860FX which has been running fine since 2008. A more general answer than for this particular situation would be appreciated.
