Model Type: 20KN
Windows 10 with latest drivers
The problem: The laptop's fan doesn't spin thus the laptop's bottom is very hot.
What I need help with: I need a way to disable the fan's shut down feature.
Please do not misunderstand, my fan can spin but it will spin briefly when I power on the laptop then when the Windows appears my fan won't spin anymore. I've found a program that can control the fan speed but it's only a partial solution!
Any help appreciated.

Welcome to the forum. Modern ThinkPads are designed to run the fan only when temperature levels get high enough to require this cooling. The fan speed also varies as temperature dictates. This is intended to reduce noise as well as wear on the fan.
So it's entirely possible that the fan behavior you're seeing is quite normal. It would be helpful if you could post the actual temperatures the E480 is encountering. One free tool to view these is Speccy. Click on the CPU and Storage tabs to get measurements, both when the fan is off and when it comes on.

A temp of 54°C seems reasonable to me, especially if the system is doing some work. This also depends on the CPU and GPU installed in the particular E480 model.
That the fan never seems to spin is more troubling, especially when others are complaining about excessive fan noise. This lengthy thread may provide some additional insights and suggestions about this issue. For example near the end a poster points out that the E480 lacks some venting that similar models like the T480 have.
