PowerBook won't power up
User reports no power at startup. He is using a 65w adapter. When I plug it in, I get a green light around the barrel .. with no battery installed. There is no light on the front either. I have checked logic board connections. I get nothing after using the board pads to power up. User replaced the board himself. Could it be the dc-in board even though I am getting a light on the barrel? Any suggestions?
