> Bug description:
> Hi, I recently purchase a Benq laptop (joybook S57B) and I experience
> trouble with the high temperature of the cpu : the bios turn off the
> machine to prevent CPU overheating. I'm currently running kernel
> 2.6.32.10-generic which comes with lucid alpha2 (january-14).
> sensors-detect do not detects the cpu's fan.
> The cooling cpu fan seems do not work at all when the kernel boot, and
> that happened with all debian-like distro i tried (karmic, lenny, debian
> testing, knoppix). However i'd say that when i turn off the laptop the
> ubuntu logo remain on the screen (which is another bug i guess linked with
> this alpha release) and suddenly the fan is working...
> I found the reporting bug/451337 seems little similar but no same. May
