This is from a GPS module manufactured by Sony, VGP-BGU1. Specifically the charging input board. Guessing they mass manufactured these with the wrong connector. The right-rear leg is ground-marked with "-" in the photo left-rear leg is marked with a "+". As you can see when the connector is moved backwards into place (removed for troubleshooting) the pos and neg terminals are directly connected through the trace on the board. Obviously it will not charge properly. Way to go Sony!
