Bug Description
Hi,
I just noticed that the fan on my Thinkpad T400 doesn't stop anymore once it got enabled. I have to unplug the AC-adapter for just a second and plug it in again, then the fan slow down or stops. Same with suspend. Fan is running → suspend → wake up after 1 second and the fan slows down or stops.

Same Problem for me here, 37°C and fan is running and running @ Lenovo T400.
Maybe tpfan is ja solution (but only on software layer..)
