MacBook Pro shuts off when uplugged, despite new, charged battery.
My MacBook Pro will only run when plugged in. The battery was old, so I replaced it, but that didn't seem to make any difference. It says that the battery is charged to 97 or 98 percent on the screen and the lights on the battery all light up when I push the tester button. Power cord, i/o board, and hard drive are all new within the last year. What should I try?
Is this a good question?
