Logic board failed due to disconnecting of battery connector
After installing my new hard drive due to the failure of the old one, my MBP could not boot up. I took it to the Apple Genius Bar and the guy said that my logic board has failed.
This was due to removing of the battery connector prior to changing the hard drive, he said. He said that the battery connector is NOT meant to be removed when you install hard drive or RAM.
I followed the guide on this site and did all the steps carefully, now I'm going to have to pay for a new logic board.
Can anyone explain this for me, I am really frustrated right now?
Did the Apple guy have big pimples on his face? He sure doesn't know what he's talking about. Removing power to the logic board had nothing to do with its failure. Try a SMC reset and let us know your results. You will need to try to start up from your original system installation DVD.
I've often removed the battery on units I was fixing for different reasons and never had a problem. So I'm not sure I understand what the Genius was telling you. It's always a good idea in pulling the power source before working on a system AC or DC as you never know when you might hit a live line or the on/off switch while changing things out which if you are not careful could damage your system.
Did you use a metal tool to pry up the connector? Thats the only thing I could think of if you shorted across the contacts some how.
