I just installed 3.7 on a presario 2100 laptop from the openbsd i386
cd. The laptop is having a problem with overheating and then shutting
off while it isn't doing anything. top reports that the cpu usage is
practically zero (it is 99.8% idle), and if I just let the laptop sit
there at a console it will slowly get warmer and warmer until it
eventually shuts off.
The fan is running at a constant speed, that sounds like its max speed
(from what I remember it sounding like in windows), but I'm not sure.
I assume that the power saving features aren't quite working yet, as
the fan starts up immediately when I turn it on after giving it enough
to completely cool down, and never turns back off again. Usually in
windows, I would power on, the fan would come on initially, and then
in a few seconds the fan would go off, if the computer had been off
long enough for it to cool down beforehand.
The laptop had never overheated (as far as I'm aware) in windows (xp),
so I'm fairly sure this isn't a hardware related problem. I've spent
the last hour or so searching the archives for overheating related and
fan related problems, but I was unable to find anything relevant.
Does anyone have any experience with this or have any idea of what the
problem might be?
My dmesg follows:
