Hum, yes, laptops suck for this, I mean, their BIOS are so limited that look useless :-/ > Also I can't find the 'acpi' command, not even with apt-file. ACPI is a package. I got it installed on both, desktops and laptops computers. http://packages.debian.org/squeeze/acpi On desktops, "acpi -V" displays little information but on laptops you can get useful values for CPU temperature, thermal trip points, fans and battery status. OTOH, lm-sensors can be also an option, as you said before, but this program has to be first tweaked to get usable and accurate values. >> By your explanation, yep, looks like the micro is reaching a high >> temperature and it shutdowns to avoid damage.

I would first look for a BIOS update if available, but yes, if you have no previous experience on laptops cleaning (while this a common task I always do by myself on desktops/servers is something I never did before on laptops) I would consider bringing the computer to the service support so they take a look (consider doing a full backup of your hard disk, just in case they break something...). It can be the fan that just needs to be replaced (maybe this is something you can try yourself) but it also can be the heatsink of the processor, that needs to be fully cleaned or even replaced with a new one, and this task can be tricky, depending on your computer brand/model.
