Won't boot up bad I/O board?
My MacBook Pro has a bad battery connector possibly. Thats what I initially suspected and hoped for. Or, it could be bad I/O board or bad logic board.
It was working fine when I shut it off one day. I came back some days later and it just wouldn’t power on again. It has a newer battery and charging cord. The thing lights up when I attach the cord.
The first pin on the battery connector has no continuity but the rest of them do. I did leave it plugged in constantly when it was working. I’m wondering if I burned something out in the battery connector. A new one is cheap but I got discouraged after someone I asked on this website said that it was likely a logic board problem and supposedly my system had that type of failure frequently.
It’s a MacBook Pro 15" non-unibody model A 1211.
I could try replacing the battery connector if it might help.
What do you think? might it be worth trying?
