ok, i have an MBP.

and every once in a while during use, it will dim the screen (like 5 bars) on its own, and then fade back to full. Its not the dimming that comes when the computer is not being used for like 5 mins before it goes to screen saver. This is different, and its really annoying.

I just want to knw if its normal, and how to turn it off
