Abstract:
A portable information handling system powered through a docking station charges an internal battery based on available power sensed at the docking station and communicated to a charger of the information handling system. A dock sensor on the information handling system selectively interfaces a local power sensor if the information handling system is not docked or a docking station sensor if the information handling system is docked. Available power sensed at the docking station is communicated to a battery charger of the information handling system by a differential wire pair interfaced through a docking connector.
