I got my [1.3 512 BTO] macbook at the very end of May.. Not sure if anyone else has noticed this but I'm having some issues with the macbook going dark.. It's as if my macbook lid has been closed. It happened a few days into ownership whilst I was on a webex, it came back after a few seconds but I had to log in again. It didn't do it again until yesterday, on a flight and watching some video's, it did it 3 times in quick succession. Anyone seeing the same? Battery is fine, it wasn't too hot... Cheers!
