[Bug 670707] [NEW] Toshiba L300D laptop overheats if in anything else but "Powersave" mode.

[Chris Eineke]

Public bug reported:

I run Ubuntu 10.10, which i dist-upgraded from 10.04, on my laptop, a
Toshiba Satellite L300D. The CPU fan only comes one when the BIOS
initializes. Once the kernel is loaded the fan stops spinning and will
never spin again at any time my laptop is running or at any CPU
temperature.

According to the temperature sensors, the CPU cores are sitting at an
idle temperature of ~66C, whereas the hard-drive is sitting at ~48C. My
laptop will generally shut down if left in the "On Demand" or
"Performance" performance profile, because the temperature goes up to
~98C and will trigger the emergency power down.

This is a regression from 10.04, where the CPU was idling at around 38C
with the fan sometimes (but not all the time) kicking and cooling it
properly.

It makes me nervous to think what this is doing to the lifetime of my
hardware.
