Fucking hell. Some fucked up shit has happend to my laptop on the short trip from my home to my mother. It boots, but very slowly, the fan spins like crazy from the moment I press the power button, and only a few programs runs. What the fuck!? Fuck everything. It's only like 2 years old.
@forteller Does it claim to be hot? Is it actually hot? Is it using lots of CPU?
For example, if the thermal sensor misreported the temperature and claimed it to be higher, this could be the effect (fans at full throttle, CPU throttling).
