    Unable to Change Brightness When Computer is Unplugged


    Hello,


    I think perhaps a recent update caused this. I am unable to change the brightness level when the computer is unplugged. When I unplug the laptop, it dims significantly so that I have trouble seeing the screen. I then click on the bottom right corner of the screen, which brings up the brightness scale, and I slide the scale but the brightness does not change. This is very annoying because I essentially cannot use the laptop now unless it is plugged in.


    Thank you

    :)

    Unable to Change Screen Brightness of Laptop


    So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
    - Reinstalling Display Drivers
    - Rolling Back Display Drivers
    - Reset Settings on UWT4
    - Power and Battery Settings
    (UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

    If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -

    Unable to change brightness on Windows 10 computer.

    Old title: Display brightness control

    I am unable to change display brightness since Windows 10 upgraded my computer from Windows 7.

    I have tried Microsoft's solution with no results.

    I have searched for the most current drivers for my AMD Radeon 6450 card, as Microsoft suggested, and have been told that I already have the most current driver.

    I still have a screen that is too bright.

    I am wearing sunglasses until I am able to adjust the brightness.

    Unable to Change Brightness When Computer is Unplugged

    Unable to change screen brightness

    I am completely unable to change my screen brightness, either through settings or the control panel. I have tried everything the internet suggested, including community solutions, but none of them work. it began after the most recent windows update, where
    the change brightness button disappeared from the battery section on the taskbar. I could change the brightness through settings for a bit, but that eventually stopped working too. although my computer says its changing the brightness of the screen, nothing
    actually happens.

    Please help me fix this! the brightness hurts my eyes and makes it hard to read text.

    thanks
