Out of nowhere (so without any sudden update or anything) my brightness fader stopped working. I can still slide it but it does not actually change the brightness. I need my laptop for work and without any other laptop to work on, this really gives me a headache to work with.
I tried updating my screen adaptors, but it does not change a thing. Somebody on youtube said I had "to activate Windows and update device drive software. Install device driver software for the device 'Intel Management Engine Interface'." But I have no idea how to do that. I have exactly the same problem as him though so if this worked for him I would like to try this solution.

Logging in and out didn't work, but restarting did! I don't know if it was the enabling and disabling of the adaptive brightness or that I had to update the screen adaptor intel, but it suddenly worked
