I'm running Ubuntu 20.04 on an older Dell laptop, and recently, I noticed that it has been getting very hot. I tried running sudo pwmconfig
, the output of which was;
Found the following fan sensors:
hwmon5/fan1_input current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
I am not sure if the fan works, nor how to start it and that is what I need to know.
