Hi
I seem to have the simular problem, but running on a regular desktop/tower PC
System all of a sudden powers off, and I have a power supply with 2 fans, video card with built-in cooling fan..
I run a motherboard diagnostic utility, and it indicates NO overheating at all
But all of a sudden, the computer powers down/shuts off
Since this has started recently (after installing a virus detection program and latest windows updates) I'll start rolling backwards uninstalling patches/virus protection program to see if that solves it..
I have a feeling there is a interupt sent from the OS, that cuses this.. In other words, something really wrong in the code somewhere...
I've updated every HW piece in my comp. with BIOS/SW updates...
