Claims21
An information handling system comprising:
- a video controller;
- a switching circuit configured to receive an input signal associated with an operating system processable by the information handling system, the switching circuit configured to provide a first power signal or a second power signal to the video controller in response to the input signal.
A method performed by an information handling system comprising:
- receiving an input signal at a switching circuit, the input signal associated with an operating system processable by the information handling system;
- and
- providing a first power signal or a second power signal from the switching circuit to a video controller in response to the input signal.
A computer program product comprising:
- a program processable by an information handling system for causing the information handling system to:
- generate an input signal associated with an operating system processable by the information handling system;
- and
- provide the input signal to a switching circuit to cause the switching circuit to provide a first power signal or a second power signal to a video controller;
- and
- an apparatus from which the program is accessible by the information handling system.
