Hi Booty,


Welcome to the Community Forums.


Try to open Power options and click on change plan settings.

Change Advance power setting then Display and look for Display Brightness.

Here you can set both On battery and Plugged in options to 100 %.

Hit Apply and ok.


Click off the adaptive brightness if needed.


Update us how it goes.
