Brightness setting not working in windows 10


I cannot change the brightness setting on my laptop (using Windows 10). The change brightness slider is active but nothing changes. The screen brightness remains the same if I set the brightness to 2% or to 100%.

brightness not working

Not sure if this is related to Windows update but, after the last update (on ‎18.‎05.‎2018), because the screen was too dark, I tried to change the brightness and found out that I can’t do it.

Thank you.
