Abstract: Systems and method are provided in which docking stations provide power to an Information Handling System (IHS) that is coupled to the docking station and provide the IHS with access to I/O (Input/Output) devices coupled to the docking station. Docking stations include a power circuit receiving a supply of DC power from an external power source. Docking stations also include a docking port used by the docking station to supply DC power to the docked IHS. Docking stations also include an I/O port the receives a connection from an external display, where a DC power input is received via the I/O port from the coupled external display. A controller of the docking station apportions the DC power input received from the coupled external display between operations of the docking station and the DC power supplied to the IHS via the docking port.

Abstract: Embodiments of systems and methods for selectively enabling and disabling protocols of a USB-C port are provided herein. According to one embodiment, a method for selectively enabling one or more protocols of a USB-C port on an information handling system (IHS) includes determining, upon system boot, if the IHS is connected via the USB-C port to a peripheral device that is authorized for use with the information handling system. If the peripheral device is not authorized for use with the IHS, the method may disable all protocols of the USB-C port. If the peripheral device is authorized for use with the IHS, the method may enable one or more protocols of the

Abstract: A docking station according to embodiments provides power to an Information Handling System (IHS) coupled to the docking station. The docking station includes a first power circuit supporting a first power output according to a power delivery protocol limited to a first power level. The docking station also includes a second power circuit supporting a second power output for providing the input power of the docking station to the IHS. A controller of the docking station determines whether the IHS requires power using the power delivery protocol and selects the operation of the first or second power circuit. The docking station may support dual of such selectable power pathways using a docking cable joined from two individual cables, where each cable provides a separate power and/or data coupling. The docking station thus supports powering devices according to a power delivery protocol or using the input power to the docking station.

Abstract: Embodiments of systems and methods are provided herein to establish a secure communication channel for communicating dock configuration actions from an administrator information handling system (IHS) to a docking station. One embodiment of such a system includes an administrator IHS configured to communicate dock configuration actions to a docking station, a host IHS configured to verify the validity of a dock certificate received from the docking station against a dock certificate authority server, and a docking station configured to verify the validity of an administrator certificate received from the admin IHS against a preconfigured list of valid administrator certificates stored within the docking station. If the validity of the dock certificate and the administrator certificate are respectively verified by the host IHS and the docking station, the host IHS and the docking station are further configured to establish the secure communication channel between the administrator IHS and the docking station.

Abstract: An information handling system receives power from a reversible power cable by selectively configuring outer pins to provide power or communication with a middle pin providing ground. A power manager of an information handling system embedded controller uses a low level of power input to determine which outer pin provides power and which provides communication, and then configures the connector to route power at a high level to the system charger for powering the information handling system.
