Debian (installing OpenSuSE or Mandriva or Ubuntu or Fedora works a

system freezes (stops responding), ramping up the CPU to 100% usage: if I
don't switch to a virtual terminal and reboot within, say, 10 minutes, the
laptop will shut itself off from overheating. Hence my assumption that the
machine simply is not DESIGNED to work at full throttle (100% CPU usage)
for any length of time. But I may be wrong, of course.

As a sidenote: I've found a thread on internet a while ago stating that you
may risk overheating and even frying a laptop if you try installing
Windows98 as a virtual machine, since Windows98 does not support the CPU
"idle" instruction. I assume something vaguely similar may be going on
here. Modern laptops with fairly powerful CPUs apparently rely on certain
subsystems of the OS to effectively prevent overheating. If some of those
subsystems don't work as expected, overheating will occur. I find it hard
to believe there aren't more laptop users with this sort of problems...

I got my granddaughter an Antec cooling pad (as distinct from a gel one) to
cope with am overheating problem in her laptop. It seems to work, especially
when the fan is running.
