Abstract
A computer system comprising a graphics processor, a frame buffer, a display device, a system agent operable to detect an absence of active software applications and system configurations capable of rendering a disruptive user experience during system suspend, and a memory for storing instructions, that when executed perform a method of entering a power conservation state. The method comprises detecting a system idle event, activating the frame buffer, and storing display information in the frame buffer from the graphics processor. The method further comprises initiating a power reduction state for the graphics processor, self-refreshing the display device during the power reduction state with the display information stored in the frame buffer, and initiating a system suspend comprising a power reduction state for the computer system provided the system agent detects the absence of disruptive software and system configurations.
