Hi all. Helping someone out with her macbook pro, all signs point (99% certain) to the DC in board connector. The Macbook pro doesn't charge battery, or power on. (with AC connection alone), nor the LED emitt at all. Yet with the AC disconnected and the battery in, the laptop runs just fine. This point me directly to the DC in board as if it were the logoc board the mac would have problems on battery too. The Macbook is out of warrenty I'm simply asking just for conformation... Am I correct in that is is the DC logic board ? As found on out, the MegaSafe port only connects via cable to the logic board, and can be replaced. Just for the record, yes... i have reset the SMC ... and have replaced with new power adapter..
