I've been running Ubuntu on my 1 y/o Dell Lattitude laptop.
Today I installed Debian squeeze and xen-4.0 on it and was surprised to see it cut out. When I rebooted a bios message told me it had previously overheated. It felt pretty hot to touch when I removed it from the docking station.
I've booted back into Ubuntu Lucid to avoid damaging the laptop. I would like to work out what caused it to overheat as I'm pretty excited having Xen on my workstation.
Any ideas on how I can track down the source of the overheating? Could it have been the fact that I was booting from esata? Does Ubuntu differ from Debian in power management?
