Did you reboot?
Did you turn it off and on again?
Why is your fault? (It's not.)
I volunteer at a charity & was using the laptop donated, I accidentally hit a key on the top right side row that dimmed the brightness almost to nothing. I don't know what I hit, but cannot get it to go back to normal! I have tried the function keys to turn up brightness, it says it's at it's peak. Also went into control center to display and it says it's all the way up! What did I do? Anyone have any idea? I am in deep do-do if I don't figure this out. Help!
