Abstract: In some examples, a system includes a primary side with a charger and a first battery and a secondary side with a second battery. The charger on the primary side can charge both the first battery and the second battery. A hinge resistance is between the primary side and the secondary side. The primary side includes a feedback controlled active device in a current path of the first battery that compensates for the hinge resistance, for connector resistances, or for battery impedances in a current path of the second battery.

Abstract: Described are mechanisms and methods to facilitate power saving in Type-C connectors. Some embodiments may comprise an interface to a Configuration Channel (CC) signal path and to a ground signal path of a Universal Serial Bus (USB) Type-C connector port, a first circuitry, and a second circuitry. The first circuitry may be operable to place toggled values on the CC signal path. The second circuitry may be operable to couple the ground signal path to a detection signal path. The placement of the toggled values on the CC signal path is enabled when the detection signal path carries a first value that corresponds with the USB Type-C connector port being connected to a USB Type-C device, and may be disabled when the detection signal path carries a second value that corresponds with the USB Type-C connector port not being connected to a USB Type-C device.

Abstract: An apparatus is provided which includes: an input/output (I/O) port to be coupled to a device external to the apparatus; a battery having an output node; a voltage regulator to selectively supply power from the I/O port to the battery, to charge the battery; and a switch coupled between the I/O port and the output node, wherein the switch is to selectively allow flow of current from the device to the output node by bypassing the voltage regulator.
