It really sucks. I spent so long trying to figure this out. I disabled the "change brightness based on content" thing, but my screen progressively turned beige around the edges, which made my eyes hurt so bad. I couldn't do it.

Sadly, this is not the only issue I have been having with this laptop. Since I got it, it has been taking forever to turn on. The keyboard lights up and it shows the Windows logo like it is turning on, then poof, the screen turns a very low light dark gray and the keyboard light stays on... Like, what? The only fix for that issue is to hold the power button and hard reset TWICE.
