Unable to set brightness level for Plugged in and on battery

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to set brightness level for plugged in and on battery.



I would like to inform you that the brightness slider to adjust brightness separately was removed from Windows 10 starting from the build version 1903. The screen brightness can be adjusted using the slider from the Notification center.



Ideally, the brightness slider will allow a user to adjust the display brightness, and that brightness will be remembered as the preferred brightness whether the laptop is on battery or connected to a charger.



However, as you have mentioned that after an update the feature is not working, we would like to know the update that was installed recently. To check go to
Start >> Settings >> Update & Security >> Windows Update >> View update history.



We would also like to know the build version of Windows installed on the computer currently. To check type: winver in the
search bar on the Taskbar and hit Enter.



Meanwhile, I would suggest you to try updating the display drivers and check if that helps. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select
   Device Manager.
   
2. Expand Display adapters.
   
3. Right click on the display
   device and select Update Driver.

Let us know how it goes.
