As the title said. Just ordered this september. Every time I connect it with an external screen, say, a projector or the dell228E at home, it freezes. Either failed to wake from sleep (freezes when the screen was still black), or just freeze where it was. Today it was the 4th freeze (I have to press and hold the power button to shut it down) in 30 days (I've only had it for 30 days!!). Any clues? Should I call Apple or what? Hardware issue or software (os) issue? Thanks! P.S. I don't have this issue on my own old powerbook 1.67. It was solid rock.
