Has anyone hot swapped their MBP battery? Well my second battery came into and i hot swapped my battery. I took out the dead battery while in sleep mode. The sleep mode went out and i quickly put in the fully charged battery in. Once the new battery was in, i tapped on the keyboard and it came back up. The screen came back up in a dimmed out grey screen with a progress bar on the bottom showing you that it was coming up. So then it loads up.. and it shows the indicator.. BUT everything is very slow. I'm getting beachballs... So simple.. I restart the system.. I'm at the startup (Grey screen, apple logo, spinning circle), and it stays there. I reset PRAM.. and still nothing. Boot from CD that came with the system.. I go into Utility Disk.. And it sees the drive after a while.. I try to repair the disk, UNREPAIRABLE. I try to repair permissions, no luck. I'm bringing it in for service.. anyone experience anything similar?
