I will keep this short, I have a Lenovo ideapad y510p with Windows 8.1 (I got it with 8.1, did not upgrade from 8) . I noticed a problem yesterday, where I cannot adjust the screen brightness. If I use the keyboard commands (Fn + Up and Fn + Down) The slider appears on the top left of the screen, as always, but does not “slide” It stays static.
If I move the slider on the Setting menu, I can slide the value but the brightness does not change and the value is not reflected on the slider on the top left of the screen.
I am not sure when this happened for the first time.
Solved! Go to Solution.

This is an old thread, but this might help someone else. Restore last restore point worked for me. I believe it has something to do with Windows Update.
