My 15" SR MBP arrived today, and it's been awesome. No problems whatsoever, until later in the day I tried using iSight for the first time. When I snapped the photo, it went "3 2 1:" and the screen went black. i couldn't do anything. I had to take out the battery and put it back in. When I restarted, the reboot was taking forever. It never got past the apple logo on the white background. So I took out the battery again and rebooted. Now it works fine, as does the iSight. Any ideas?
