    Can't adjust screen brightness


    Hi there,


    Right after I updated the latest version of windows 10, I can't change the screen brightness for my laptop. All display adapters are up to date. No brightness slidebar shown in "Settings"->"Display"->"Brightness and color". I also tried my hot key FN+F12 to adjust the brightness, and a vertical bar showed up but the brightness didn't change.

    By the way, I haven't seen slidebar if I click on the battery icon on the bottom right corner even in the past when there WAS a slidebar in "Settings"->"Display"->"Brightness and color". There wasn't a checkbox to add it to the battery icon. I also tried many other ways yet none of them works.

    Is there a way to fix these two problems?


    Here are the screenshots attached to be clearer:

  2. screen brightness on windows 10

    Hi,

    Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

    To manually adjust the screen brightness, we suggest following these troubleshooting steps:

    • Click Start, then select Settings.
    • Choose System, then select Display.
    • Under Brightness and color, move the Change brightness slider to adjust the brightness.

    Feel free to post back if you have other concern.
