On my new MB display sometimes gradually getting dimmer and then brighter every few seconds even when I use it. It looks like it happened on battery power but on fully charged. I did not see this on my IMac. Does anybody have that? Is it suppose to be that way?
 
its a setting in system prefs -> displays -> Auto adjust brightness as ambient light changes.

it annoyed me too at first, i just had to turn it off
 
isnt it "Automatically reduce the brightness… before sleep" in Energy Saver preferences? this is the annoying setting as it dims the display instantly before sleep and then pressing a key or touching the mouse will brighten it again.

the ambient light sensor will gradually dim/brighten the display to suit your background rather than instant dimming.

Nope, its definatly what SelfMadeCelo described, i turned mine off, as the tv was causing my mb screen to change all the time when in the livingroom in the evening.

Had the same problem - either the TV would cause it to change, or when family members switched lamps on/off. Annoyed me until I turned it off. :)

On the Macbook the sensor is the iSight camera, or at least it's in the same place as the iSight. Try passing your hand over it. It's different on the MB Pro, but I'm not sure where.

The unibody has the sensor next to the isight, regardless if its a macbook (pro) or (air). The older generation macbook pro's sensors are in the speaker grills (both left and right).
 
this happened to me last weekend. i didnt know it had an auto dimmer. sitting there using it and its like hmm a little to dark for some reason. so i reach up and tilt the screen back (covering the isite) all of a sudden it was like someone hammered my brightness all the way up. im like ok thats good i let go then it turned back down. its like wtf! now its too dim again. im not to bright myself so haha. yea anyway enjoy your mac
