[Bug 508674] Re: CPU cooling fan doesn't work at all on lucid

[fang]

** Description changed:

- 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. 
+ 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 anybody found that same issue on that laptop in order to release a patch to solve it ? Regarding all the kernel i tried, I now considering that a best option will be to change the cpu cooling fan for another one compatible with the ubuntu hardware request. Can you please help me to solve that issue or provide advice on a model/brand for a new fan. Many thanks.
