Public bug reported:
I installed Ubuntu 12.10 on my work computer, a HP ProBook 6450b. When I
use many applications, and a virtual machine, it uses a lot of CPU.
Under such circumstances, my CPU starts overheating (that's my guess),
and it can lead to an abrupt shutdown of my PC, without any notice.
With lm-sensors, I notice my CPU temperature gets as high as 105 °C,
which is the critical limit. However, I can't see my CPU Fan speed,
although I can hear it run at high seed.
