So, I just got a brand-new 15' MBP, which shipped with the Leopard Upgrade DVD. Everything went fine in terms of installation, but I've noticed a problem two times now. For one thing, shutting down takes a bit of time--but starting up is a whole other issue. It takes forever, often times it never gets past the white screen, and it just sits there. It did it once, and after waiting a bit it finally got to the Apple logo and took a bit of time to load, but then worked fine. Just recently I shut it down (to be nice) and decided to start it back up again. Went through the same problem, but this time, after a while, a blinking Earth appeared on the screen where the Apple logo normally is. Only thing that I can think is that its some sort of network symbol, as my network cable was unplugged once it finally started up. I figured that I'd better ask now while the computer's still under warranty and in case its a sign of a bigger problem. I do have an external HD, and I have a Tiger install DVD so I could easily do a fresh install/upgrade if needed. Any help would be appreciated.
