I am on vacation at a ski resort. My Macbook would not reawaken from sleep mode so I held the power button down to do a cold start. Now all I get is the logo and spinning gear. I searched the forums and the apple website and I have tried to reset the PRAM and restarted in Safe Boot. Still the same. I do not have my Install disc with me and I don't think there is a Apple Store anywhere near by. Is there anything I can do? It is going to be a long week if I cannot get this going.
