Hi. Long Time No Post!! Until recently, everything has been fine for my MBA. So I have not had a need to post here. But I do come by frequently and read the Front Page Articles and occasionally browse the forums. But, now I have an issue that has brought me back here to throw myself on the mercy of the forums. I would like to get some help please.
My 2011 MBA 11" has started flashing the screen brightness. Goes dim and bright. Can change as often as about once every 1 or 2 seconds. Will do it for awhile, then stop and act normal again.
I disabled the Auto Dim Feature a long time ago. But honestly, have not checked it recently to make sure it has not come back on. I will do that tonight when I get home.
The dimming seems almost like the change that happens when you connect, or disconnect, the power cable. But, the charging indicator is not going off and on with the change in brightness. The battery stays fully charged. I have 2 power supplies, and it has happened with both of them.
I have wiggled and jiggled the magsafe connector and it does not cause the problem. So does not seem to be the magsafe socket.
Moving the LCD back and forth does not cause it either. So does not seem to be an internal cable issue either.
About the only thing I can think of that is common when it happens is that I have been watching online videos or flash animations and the CPU fan has been running fast. So it may be an overheat issue.
Any other ideas or suggestions you can give?
