However, when I hibernate, the fan suddenly slows down shortly before the laptop turns off. After resume, fan control works perfectly: Fan changes speed and turns on and of depending on temperature. Somehow, hibernation *fixes* fan control. This is in contrast to other reports, which mostly report that fan control breaks after hibernation. I tried to find the place where the magic happens, reading through the pm-action script. Finally, I found that it must happen in the kernel, as simply doing # echo -n disk > /sys/power/state is enough to trigger the effect. So: what is it in the hibernation process that fixes fan control on the AMILO Pro V2030?
