A couple of days ago my MacBook Pro 17" which is running on Leopard (I assume the latest version) had a problem. Safari quit unexpectly - twice. As I don't shut my laptop down often I thought I would do a restart to get it going again. So, I did a restart by hitting the power button. The shutdown process timed out as something wasn't shutting down - not sure what. But I closed all the windows manually & it was on it's way (shut down & then started the reboot). On the reboot or restart (whatever you call it) it got stuck on the grey screen with the apple sybol & the wheel running. I am not sure how long it got stuck there but my battery was so hot that I was lucky I didn't burn the house down. I disconnected the power & took the battery out until it cooled down. Once it was cooled, I plugged it all back together & tried again with no success. Normally when it gets stuck pulling the battery out & starting again normally fixes the problem (I had the battery replaced as it bulged & was overheating about a year ago). Anyhow, this time no success. I have tried holding the power button in with the battery out etc (not sure of what this does technically) and have tried starting it up in safe mode. Neither have worked. It is still stuck on that same screen. I have read that you can do like a command promt on start up to possibly fix the problem - but I am a bit scared of doing this one and would like to use it as a last resort. Any other suggestions?
