I have a 3 yr old, apparently broken Macbook pro here (17") which I gave up on after the warranty expired early last year. It isn't an emergency situation as I have a new machine, but would love to know if anything could be done to help the old one. Symptoms: When booting, only grey screen with Apple logo appears with the spinning dial beneath it. Nothing else. It remains like that, until rebooting itself all over again, only to stick on the same screen. I do hear the chime, but that is all. Power cable working well. Did try various stuff at the time, like holding down command + C, etc, but no joy. Any ideas? Just give up the ghost?
