1. An information handling system comprising: a housing; a processor disposed in the housing and operable to execute instructions that process information; a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information; a keyboard having plural keys to accept end user key inputs, a wireless network interface controller to communicate the key inputs to the processor, and a charger port to accept power, the charger port having a first magnet on a first side with a first pole orientation and a second magnet on a second side having a second pole orientation opposite the first pole orientation, the charging port further having at least four separate contacts including at least a separate power contact, a separate ground contact, and first and second separate communication contacts; and a charging connector sized to fit in the charging port, the charging connector having a third magnet with the first pole orientation and a fourth magnet with the second pole orientation, a power contact, a ground contact and first and second communication contacts; wherein the separate power contact and the power contact align when the first magnet attracts to the fourth magnet and the second magnet attracts to the third magnet when the charging connector couples in a first orientation relative to the charging port to communicate power, and the power contact fails to communicate power when the charging connector couples in a second orientation relative to the charging port and inverse the first orientation; and wherein when the first magnet aliens with the third magnet: the power contact aligns with one of the first and second separate communication contacts; and the ground contact aligns with the other of the first and second separate communication contacts.
