    Brightness slider not working


    I recently went on a trip to California, where I took my laptop with me for schoolwork. I left it sitting in my bag during the bus ride over, and when I got back home from California I encountered the most annoying bug. The Brightness slider, the small, easy-access one used by tapping Fn + F5/F6 will not go off my screen, even when I am not touching the computer. Trying to interact with the slider at all does nothing, as the brightness just keeps upping itself to the max brightness. I have looked all over and cannot find any reasons for this. What can I do to fix it?

    :)

    Brightness Slider Gone from Power Plan

    Hi,

    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
      section.
    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.

    Regards,
