SYSTEMS AND METHODS FOR COMMUNICATING POWER EVENT OF DISPLAY DEVICE COUPLED TO INFORMATION HANDLING SYSTEM

1 . A system comprising:

an input for receiving a stimulus to modify a power state of the system; and

a controller configured to:

monitor for user interaction with the input; and

in response to user interaction with the input, communicate a message via a vendor-defined message over a communications interface to a second controller integral to an information handling system, wherein such second controller is configured to replicate the message to a management controller integral to the information handling system to cause the management controller to change a power state of the information handling system.

2 . The system of claim 1 , wherein the system is a display device communicatively coupled to the information handling system.

3 . The system of claim 1 , wherein the communications interface comprises configuration channel pins of a Universal Serial Bus Power Delivery interface between the system and the information handling system.

4 . The system of claim 3 , wherein:

the controller comprises a first Universal Serial Bus Power Delivery controller; and

the second controller comprises a second Universal Serial Bus Power Delivery controller.

5 . The system of claim 1 , wherein the input is a power button.

6 . A method comprising:

monitoring, with a controller, for user interaction with an input for receiving a stimulus to modify a power state of a system; and

in response to user interaction with the input, communicating a message via a vendor-defined message over a communications interface to a second controller integral to an information handling system, wherein such second controller is configured to replicate the message to a management controller integral to the information handling system to cause the management controller to change a power state of the information handling system.

7 . The method of claim 6 , wherein the system is a display device communicatively coupled to the information handling system.

8 . The method of claim 6 , wherein the communications interface comprises configuration channel pins of a Universal Serial Bus Power Delivery interface between the system and the information handling system.

9 . The method of claim 8 , wherein:

the controller comprises a first Universal Serial Bus Power Delivery controller; and

the second controller comprises a second Universal Serial Bus Power Delivery controller.

10 . The method of claim 6 , wherein the input is a power button.

11 . An article of manufacture comprising:

a non-transitory computer-readable medium; and

computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:

monitor, with a controller, for user interaction with an input for receiving a stimulus to modify a power state of a system; and

in response to user interaction with the input, communicate a message via a vendor-defined message over a communications interface to a second controller integral to an information handling system, wherein such second controller is configured to replicate the message to a management controller integral to the information handling system to cause the management controller to change a power state of the information handling system.

12 . The article of claim 11 , wherein the system is a display device communicatively coupled to the information handling system.

13 . The article of claim 11 , wherein the communications interface comprises configuration channel pins of a Universal Serial Bus Power Delivery interface between the system and the information handling system.

14 . The article of claim 13 , wherein:

the controller comprises a first Universal Serial Bus Power Delivery controller; and

the second controller comprises a second Universal Serial Bus Power Delivery controller.

15 . The article of claim 11 , wherein the input is a power button.
