I need to show a repeating slidewhow via a lcd projector using my MB-A running iPhoto. Is there some way I can a) shut off the screen to save battery life or b) close the lid of the MB-A with the same effect?
You'll have to have external power for Clamshell mode. You could just use the F1 key to reduce the brightness as far as it goes.
