tcthomas2, try to reseat the cable. It can go in a little crooked or not deep enough to make proper contact. Also, be aware that the battery connector has a nasty tendency of breaking of the board. Check yours to make sure it is not loose already. When you move the clip that holds the cable in the connector, use a L-shaped paperclip or similar device to pull straight up on the clip. Any bending on an angle can dislodge the connector.
