Information handling system docking with cable based power and video management

摘要

A docking station connects through a docking port and docking cable with an information handling system to support communication between the information handling system and docking station peripherals. The docking cable includes an integrated input device, such as a mechanical button or fingerprint scanner, which accepts an end user input to command a power state transition at the information handling system, such as a transition between an on state and a reduced power state. The power state transition is sent directly from the integrated input device to the information handling system or, alternatively, from the integrated input device to the docking station and then from the docking station to the information handling system.

主权项

1. An information handling system comprising:
a housing having a rotationally-coupled lid that rotates between open and closed positions, the closed position covering a power button to make the power button inaccessible to the end user; a processor disposed in the housing, the processor operable to execute instructions for processing information; memory disposed in the housing, the memory interfaced with the processor and operable to store the instructions and information; a docking manager disposed in the housing, the docking manager operable to manage interactions with an external docking station through a docking port; a docking port disposed in the housing and interfaced with the docking manager, the docking port having plural data lanes to communicate information with the external docking station; and a docking cable adapted to couple to the docking port at a first end and the external docking station at a second end, the docking cable having an integrated input device proximate the first end, the integrated input device operable to accept an end user input and initiate a change in a power state of the processor in response to the end user input, including at least commanding a power on of the processor with the housing lid in the closed position; wherein the integrated input device comprises a mechanical button that accepts an end user input and sends a signal to the external docking station in response to the end user input, the external docking station operable to command the change in power state of the processor in response to the end user input.
