    No options to turn OFF adaptive brightness / no power slider


    Hello everyone!

    I'm stuck with a very weird problem I can't solve. I'm not a full-on reading binary style tech person but I'm using computers (and fix their problems) since forever and never ran against a wall like this:

    My Dell M3800 laptop turned on the adaptive brightness feature again that I disabled almost three years ago. Now it's pretty much useless in dim environments because the screen gets so dark. Also every option windows normally has to switch it off is gone. Not greyed out, it's just not there (Both in the legacy power options and in te new UI).

    Around the same time it happend that windows decided to get rid of the old power profiles and instead only show the "balanced" one that comes with the power options slider when you click on the battery icon in the tray. I had that briefly and then the slider disappeard along with the option of turning adaptive brightness OFF.

    This makes me MAD.
    • I deleted and restored the default power plans in several ways
    • I changed all (all I found, though) corresponding registry entries to disable adaptive brightness
    • I checked the registry for the the option to show the switching-option being ENABLED
    • I even stopped the windows service for the ambient light sensor

    No change. Any Wizards around? *Shock

    No option or slider to adjust Brightness ?


    Brightness sliders are only in !all in ones", like laptops, and tablets I believe.

    Intel Compute Stick.
    Windows 10 Home. 1709 Build 16299.248.

    The usual brightness slider is nowhere to be found. Not in Power Options nor Settings > System > Display.

    It is too bright. Hurting my eyes.
