    Since I’ve installed the Windows 10 Fall update i cannot adjust brightness anymore. Every time I try to fix anything on my AMD driver (turn it on, update, try new drivers specific for brightness), my screen goes black and I have to turn off the AMD driver in safe modus. Now I have the basic driver installed and on, but I still cannot adjust brightness. Any button or slider does not appear anywhere. Even though I have ticked on the option to reduce screen brightness when my battery is low, nothing happens if my battery is low. I only have a slider when I go into the options for my battery, but the slider does not do anything to my screen brightness. Do you maybe have a fix for my problem? My laptop is a Lenovo E50-70.

  • Worked great! Thanks!
