You have my sympathy. This laptop that runs hot when busy (up to 98.5°C; I underreported the maximum a week ago) has never frozen or rebooted when particularly stressed. However, during the time of squeeze, it would turn itself off spontaneously (hard power-off like holding the power button), usually when you disturbed the angle of the screen (even slightly). It never happened after installing wheezy, but since about a year ago the screen goes very dark after a second or two. That happens at boot up (before the POST is finished) and also when exiting X to a VC (normal for a second, then dark again). These fleeting glimpses are the reason I can't ever seriously upgrade it. I use it with a monitor but that get a signal during the POST or CMOS. So maybe you're lucky and it'll just go away, but it sounds as if you have a reasonable workaround. (I've never run a laptop for as long as those uptimes you're reporting.) Cheers, David.
