Abstract
A computer system comprising: a graphics processor, a display controller comprising a display-local frame buffer, a display device, and a memory. The memory stores instructions, that when executed by the computer system, perform a method of entering a power management state. The method comprises detecting that the computer system is idle and optional proximity detector for determining if a user is present in front of the system. With the computer system idle, and the user in proximity of the system, the display-local frame buffer is activated. Display information transmitted by the graphics processor is stored in the display-local frame buffer. Initially a power reduction state is initiated for the graphics subsystem including the graphics processor, and the display device is placed in a self-refresh state with the display self-refreshing from information stored in the local frame buffer.
