    Backlight suddenly stopped working. When awakened or turned on, display will work for a few seconds, then goes out. I can see the display just barely (as if brightness turned all the way down). I can use external monitor. Also, keyboard backlight non-op. When I attempt to adjust, I get the circle w/ slash (like a no smoking symbol).

    The sleeping eye on the front is also dark when computer is on (but works when the computer sleeps).... I think it's usually dimly lit when lid is open. Are all these things linked?

    Any ideas?

    also, searched posts and saw similar questions.... none resolved however.

    Follow up

    Did PRAM/SMC resets for the umpteenth time. Keyboard backlight works.... still no display backlight.

    Could be a backlight fail... or worse, a Logic Board fail. Not sure though.

    Sorry, I realize that wasn't very helpful... I wish the best of luck to fixing the issue.

    Resolved... for now

    I only post this because so few people post the resolution to their problem.

    Stupidly, when the keyboard backlight resumed working, I was still using the external monitor.... not realizing that the display goes dark when you're connected externally. When I unplugged, lo and behold, the display was on. I guess PRAM/SMC resets fixed it.
