after I reinstalled windows on my Acer Swift 3 sf314-41 I lost all access to the brightness hotkeys ( f3,f4) the keys themselves still work but the brightness controls don't, holding the fn key with these does nothing.
I've tried to change it through the settings app and the action centre it isn't there how do I fix it?
