The fan on my rather old (>5 years) Thinkpad sometimes stops working. Running the sensors command shows:
thinkpad-isa-0000
Adapter: ISA adapter
fan1: 65535 RPM
i.e. the number of revs goes crazy (the normal value is up to 4600 rpm).
I have tried running pwmconfig as suggested in this post, as well as the lengthy command presented in this post. However, none of this worked, and to restart the fan I always had to restart the computer.
Is there possibly any other way to restart the fan?
