    Brightness control not working Windows 10 / Lenovo T450s


    Hi,


    After the last Windows 10 update from 9th Oct 2018, my Lenovo T450s laptop is not capable anymore to adjust brightness. Hotkeys not working not the slide bar for Display Brightness. I can slide up or down but the screen does not change brightness level. I've tried all kind of solution after surfing the net, from updating video adapter drivers from intel and from lenovo as well, monitor drivers, changed FeatureTestControl registry key, but nothing works.

    Please help with other ideas.


    Thanks,

    Stefan

    :)

    Brightness Control not working in Windows 10

    Hi Ella,

    To adjust the brightness, see the steps below:

    • Go back to Power Options, and tick on the High performance.
    • See if you can adjust the brightness.

    If this not work, we highly suggest that you create an Administrator account, and re-do the steps above.

    Let us know how it goes.
