Okay, help me out here guys. I've had my new mbp for about a month, but I can't figure out how to stop the screen from dimming on it's own. This is probably an easy fix but I'm a noob so go easy on me lol. I already went into my my energy saver preferences and checked off the box saying to automatically reduce the display brightness before display sleep... but every now and then, it still dims on its own if I don't use the computer for say 10-15 minutes. Am I missing something, is there another preference I need ot be looking for?
