Had my Macbook less than a week, and got some questions. I've turned off "Automatically reduce the brightness of the display before sleep" in Energy Saver, yet three minutes without using the Macbook, it dims. Is this normal? Secondly, even after doing the battery calibration, my charge level always goes down to 99%. Lastly, I notice the display has uneven brightness (worse backlight bleed along the bottom), but I guess there really isn't much I can do about that other than complain to Apple and get it replaced. Haven't decided if its worth bothering.
