Hey guys I have been using my new mba 13 in for a month now and it keeps auto dimming by itself. I turned it off in the energy saver profile. I have it unplugged and every couple minutes it keeps dimming by itself.

So you turned off auto brightness or the setting in Energy Saver that says "slightly dim while on battery power"?

there's also the ambient light sensor.

in settings > display there's an option to "automatically adjust brightness" that you can go ahead and turn off.

i suspect one (or both) of those is still on. check that and let us know if it's still doing it.
