It's better to burn out then to fade away

MacBook Pro screen weirdness - feature or bug?
I just bought a MacBook Pro two weeks ago. Haven't used a Mac since college (I think I mentioned this in my last question about Macs). When I am on battery power, the screen will modulate in brightness - fading in and out occassionally. It never really goes dark, but about every 3 minutes it will fade briefly then flare back up to normal brightness. Is this a setting I don't know about - some kind of power saving thing? Or is there something wrong and I should be concerned?

Changes in screen brightness can also inadvertently be triggered by moving a hand over the light sensors, which are I believe located in the grilles to the left and right of the keyboard.

The behavior that whiskeyspider describes is especially noticeable when the ambient light in the room is dark. You can also provoke this behavior by holding your hands or an opaque object near the top row of keys. Turn it off as s/he describes.

I think what you are describing is different than the automatic light sensor brightness adjustment.
It's a power saving feature, it can be turned off under Energy Saver, and then select "Settings for: Battery". I think the relevant setting is "Automatically reduce the brightness before display sleep."

Response by poster: Kenliu, no it was what whiskeyspider said. Also, the other information about the sensors is greatly helpful. Thanks everyone!
