  1. Brightness slider not functioning

    Good afternoon!

    Today I have a driver issue. In windows, the brightness slider does not adjust the brightness of my laptop monitor. I have tried everything, from registries to device manager, and this is my last attempt to find an solution that doesn't involve me wiping my drive. Please please please help me, in any way you can.

    Brightness slider replacing brightness quick action button from 1903

    Hi all

    Does anyone else feel like they've lost some functionality here?

    For clarity, I'm talking about option 3 in this very useful guide.

    I understand that the new slider gives more control, but the previous method was very quick to change in increments of 25%, and I tend not to always need such granular controls beyond this.

    My suggestion would be to keep the slider, but to turn the bulb icon just to the left of it into a button which increases the brightness in 25% increments per the previous quick action button functionality.

    Brightness Slider Gone from Power Plan


    Thank you for writing to Microsoft Community Forums.

    Select action center/notification button on the right side of the taskbar, and then move the
    Brightness slider to adjust the brightness. As mentioned in the article, if you
    don't have a desktop PC and the slider doesn't appear or work, try updating the display driver.
    As you have already update the Display drivers, I would suggest you to uninstall and delete the drivers then update it again. To uninstall and delete the drivers, please follow the steps mentioned below:

    1. Open Device Manager and then expand the Display adapters
    2. Then right click on options listed below and click on Uninstall.
    3. Check the box next to Delete this drivers.
    4. Then reboot your device and update the drivers. You can also try updating the Batteries drivers along with display drivers from manufacturer’s website.

    Brightness slider not functioning

    Changing brightness is no longer smooth with function keys on 1903

    Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

    If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
    Press a key, plus scroll, and adjust your brightness.

    The key and the steps are your choice.

    Oh, and it can adjust volume similarly.

    Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.
