Abstract
A USB Type C connector port adapts to support docking solutions with enhanced power transfer features, including increased power transfer levels supported through a guide pin and connector interface, rapid power transfer configuration changes by applying pre-negotiated power settings, external battery charge and discharge at an information handling system with improved efficiency accomplished by transitioning voltage between native and boosted levels responsive to information handling system load, and robust connector port coupling in a cavity of a connector shell.
Claims16
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions that process information;
- memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- a power manager disposed in the housing and operable to manage power applied to the processor and memory;
- a communications controller interfaced with the processor and the power manager, the communications controller operable to manage an interface with an external device to communicate power and data with the external device;
- a connector port disposed at the housing and interfaced with the communications controller, the connector port having data and power pins to interface data and power with the external device through a connector cable;
- a power negotiator interfaced with the communications controller and operable to negotiate power settings for power transfer to and from the external device and to store the power settings for application by the communications controller;
- a docking station coupled with the connector port as the external device;
- one or more peripherals coupled to the docking station and interfaced with the connector port through the docking station;
- wherein the communications controller selectively receives power from the docking station and provides power to the docking station with the power settings, the power provided to the docking station used at the docking station to power the one or more peripherals;
- a charge controller disposed in the housing and operable to provide power from an external source for use by the power manager;
- a battery disposed in the housing and operable to provide power for use by the power manager, the battery interfaced with the charge controller to accept a charge when the charge controller interfaces with an external source;
- a first power direction switch disposed between the port and the charge controller and interfaced with the power manager;
- a second power direction switch disposed between the port and the battery and interfaced with the power manager;
- wherein the power manager turns off the first power direction switch and on the second power direction switch to change the direction of power between the external device and information handling system.

A method for transferring power between an information handling system and external device through a communications port, the method comprising:
- detecting insertion of a connector into the communications port of the information handling system, the connector interfaced with the external device;
- exchanging power capabilities between the information handling system and external device through the communications port;
- negotiating first power transfer settings for power transfer from the external device to the information handling system through the communications port;
- pre-negotiating second power transfer settings for power transfer from the information handling system to the external device through the communications port;
- storing the pre-negotiated second power transfer settings;
- and
- initiating power transfer from the external device to the information handling system with the first power settings;
- detecting a predetermined condition;
- and
- in response to the predetermined condition, applying the stored pre-negotiated second power transfer settings to initiate power transfer from the information handling system to the external device,
- wherein the predetermined condition comprises an interruption of power transfer from the external device to the information handling system.
8 more elements
A system for transferring power between an information handling system and an external device through a communications port, the system comprising:
- a communications port configured to integrate in the information handling system, the communications port having power pins for communicating power and data pins for communicating data;
- a power negotiator interfaced with the communications port and operable upon detection of an external device connection to the communication port to negotiate first power transfer settings to transfer power from the external device to the information handling system and second power transfer settings to transfer power from the information handling system to the external device, the power negotiator saving the first and second power transfer settings;
- a power manager interfaced with the power negotiator, the power manager operable to command power transfer to the information handling system with the first power transfer settings and to command power transfer from the information handling system with the second power transfer settings;
- and
- first and second power direction switches interfaced with the power manager and operable to configure the information handling system to transition between receiving power and sending power when the power manager applies the first power transfer settings and the second power transfer settings.
