Hello,

I have a fujitsu-siemens amilo l1310g laptop. The problem is that the cpu fan doesn't start if the cpu heats up, but I can start it manualy by these 2 commands:

echo 3 > /proc/acpi/fan/FAN0/state
echo 0 > /proc/acpi/fan/FAN0/state

in this case the fan starts but it won't ever stop even if I launch:

echo 3 > /proc/acpi/fan/FAN0/state

I'm using kernel 2.6.18, but tried with 2.6.19 and 2.6.20-rc7 also. Any hint on how can be this fixed? Thanks.

What are the contents of /proc/acpi/thermal_zone/ ?
