Comment 12 for bug 451337

I have almost the same problem. I am on a Fujitsu Siemens Amilo L1310G. If the laptop is cold (below 50 C) when I start it, the fan does not start at all. If it is warm when I start it, the fan runs until the temperature is below 50 C. The fan then turns off, never to turn on again (even if the temperatures rise above 50C).

The same issue existed in every version I've tried (I started using Ubuntu with 8.04), but there was a patch on the laptop testing page (https://wiki.ubuntu.com/LaptopTestingTeam/FujitsuAmiloL1310G under "From the start). This patch made the fan run all the time which was no problem. This patch does, however, not seem to work with GRUB 2. I can at least not find a way of getting it to work.

What can I do to help you fix this bug?
