    Can't adjust brightness when the power plugged or unplugged


    Hi there,

    • Previous status:

    brightness 100%, plugged in; brightness 50%, unplugged.

    When I unplugged the laptop, the brightness will decrease down to 50%. And will increase back to 100% when the laptop plugged in back automatically.

    • Current status:

    Always keep the last brightness setting, no matter laptop plugged in or unplugged, the brightness doesn't change.


    Is there any way to fix this problem? Thanks!

    :)

    Windows brightness stays the same when plugged and unplugged

    My windows brightness stays the same when I plug and unplug the charger. It used to change to a lower brightness level when I unplug and adjust to my default brightness level when plugged in. But now when I change in the brightness level, it stays the
    same even when I plug it in. Is there a way to have distinct brightness levels depending on whether my computer is plugged in or not?

    Screen brightness when plugged/unplugged

    Its probably something to do with your power plan settings. See this article for full details - https://www.howtogeek.com/241771/ho...screen-brightness-manually-and-automatically/ mainly
    the section entitled "How to Automatically Adjust Brightness When You’re Plugged In" and look at your PCs brightness setting when its 'plugged in' as opposed to 'on battery' under the
    “Adjust plan brightness” controls.

    However, when on battery the brighter the display is, the shorter the battery life is likely to be.
