Brightness Not Working Windows 10. This problem in the relevant drivers doesn't allow you to adjust your display brightness. I can find no way to adjust it.
If brightness control key are missing or not working on your PC or laptop, try restarting your computer, updating Windows and check if the problem persists. Repeat for any additional adapters listed within. Also, some of the users on Microsoft Forum have claimed that they are unable to.
If the above steps are not working for you, then please comment below.
If you have enabled automatic battery management then if the battery starts to become.
If new updates are found, it will automatically install them. This issue mainly affects laptops running Intel processors. Of course brightnes settings didn't work.
