## Abstract

A system may include 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 3)

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.

### Claim 5 (depends on 1)

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

### Claim 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.

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 6)

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.

### Claim 9 (depends on 8)

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.

### Claim 10 (depends on 6)

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

### Claim 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.

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 11)

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.

### Claim 14 (depends on 13)

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.

### Claim 15 (depends on 11)

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