If I resume from suspend, the fan runs constantly. There is no disk or cpu activity to cause this. The laptop is running on battery.

If I plug in the power cable and unplug it again the fan stops (back to normal).

I think the acpi information is wrong:

# cat /proc/acpi/fan/*/state
status:                  off
status:                  off
status:                  off
status:                  off
status:                  off

This seems to do it:

for i in /proc/acpi/fan/FAN*/state; do echo 3 > $i; done

Not sure what 3 means though.

Sorry, that's wrong. This works:

for i in /proc/acpi/fan/FAN*/state; do echo 0 > $i; done
for i in /proc/acpi/fan/FAN*/state; do echo 3 > $i; done
