    Fn Brightness not working after Windows Update (Dell)


    Hello.

    Fn brightness function was working correctly, until a windows update about 3 weeks ago.

    Then I tried to fix it by going to the device manager and then updating the drivers. (Monitors- Generic Pnp Monitor - Update - Browse my computer for drivers - Let me pick from a list of availabe drivers on my computer- Generic Pnp Monitor)
    HwId SEC544B

    The fix was temporary and I couldn't use the Fn brightness keys after a laptop restart.

    Now I tried unistalling the driver and restarting my laptop. Now the brightness dosen't change at all even after using Mobility Center.

    Is there any fix for this?

    Dell Latitude E6520
    Intel hd3000
    Version 2004 ( OS build 19041.685)

    Thank you!

    :)

    Dell e6220 fn keys can't adjust brightness on windows 10

    My dell e6220 can't adjust brightness on windows 10 via fn+arrow up/down combination. However it is possible to adjust brightness using power management window, or notification panel. Also, after intel hd 3000 updating driver in device management window,
    it's possible to change brightness via fn+arrow up/down combination, until I restart pc.

    p.s. sorry for my english.

    Fn Brightness not working after Windows Update (Dell)

    Brightness buttons not working (but the rest of the fn keys do)

    I have a Dell XPS 13 (2016 version) and the brightness Fn keys suddenly stopped working. I updated my display driver, but the buttons still don't work. When I press one of them, my brightness indicator shows up in the top left corner of my screen, but it doesn't move. The rest of my Fn keys work fine, only the brightness keys don't work. Windows updated recently and I'm on the Slow channel of the Windows Insider Program, so I'm thinking there's a bug in that update that broke my brightness keys. Is there a way I can fix them?
