Hi all,

I absolutely love my 13" MBA Ultimate...just an outstanding machine. However, the brightness seems to change all by itself sometimes after it's been asleep. Sometimes after being asleep I touch the keyboard and the brightness is at max...practically blinding me. lol. Anyone else experience this behavior?

All MacBooks have the same system. Just depends on the room lighting.

I wasn't aware MBA had a light sensor

It doesn't.

Didn't think so. So the reason being the room light is false

Exactly...I don't even have the check mark shown in the screen shot above which appears to be a Cinema Display thing.

It is just a screenshot, as I don't have an MBA handy to deliver an appropriate screenshot. I didn't know, the MBA does not have such sensor, as it is located near the iSight camera.

I notice this seems to happen when my MacBook Air is running on the battery source. When itís running the electrical power, it remains fully bright.
