Do you have the laptop resting on a flat surface? My University used
Compaq and HP laptops (I have an n800w), and the solution to overheating
that I always heard from fellow students was to not leave the laptop on
flat surfaces. They'd prop laptops up with all sorts of things like
erasers, triangular drafting scales, and folded paper.
Also, are those temperatures supposed to be Celsius? I'm nut sure about
Pentium Ms, but 100F wouldn't be hot for most modern CPUs.

Hi,

My laptop (HP nc8000) overheats (85-100F) when running cpu simulators like bochs
and simulavr.  I guess this is a hardware problem but wanted to rule
out any misconfigurations on my part or software issues that may be
related.  The laptop doesn't overheat during buildworlds though this
isn't a constant CPU workout either.  Included is a copy of
/var/run/dmesg.boot and my kernel config file.
100F would be quite cool, perhaps even for a Pentium M (~37C). On the 
other hand 100C would be quite hot, especially for a mobile processor, 
are you sure that your fan is working and that the heatsink hasn't come 
loose?
