Having problems with keyboard.
I just replaced the logic board. The macine will only boot up on the battery, and there is no keyboard control, or back light. Can not charge machine with wall charger, even though I get a green light on the charger. I was thinking about the left I/O board, but don't understand why the keyboard won't funtion when its pluged into the logic board, and there is enough power on the logic board to boot the macine, and run the screen. Does anyone have a sugjestion as I would should try next? Should the keyboard be working?
Is this a good question?
