Hi, My battery died and after that my 2.16ghz 17" MPB have become incredibly slow. Xbench gives me a 52.55 score which is about the same as old macmini. Energy saving options are showing full performance and machine have been rebooted many times. Next i was thinking to re-install OSX, but I doubt it will help. I have been waiting a new battery for 3 weeks now, so i hope i dont have bring my machine into the repair service as it will probably take even more time.
