[ltp] Re: An "inverse" fan problem

[Jared Warren]

I'm running Ubuntu/unstable on a X31 and my fan also never seems to
turn on. My CPU temperature is regularly above 50 and I've seen it go
over 70 (but I usually shut down manually if it hits 60) with similar
GPU temps. Sending a speed command to /proc/acpi/ibm/fan doesn't seem
to do anything. Nor does setting my trip_points which are, on bootup:
critical: 91
passive: 86

It's almost always too hot to keep on my lap. How can I start
diagnosing this problem?
