ABSTRACT:
A touch screen power control function in a computer system, wherein a touch screen input device is employed to control power modes for the computer system. A touch screen controller senses a touch input from the touch screen input device. If the computer system is in a full power mode, the touch screen controller determines the input coordinates corresponding to the touch input, and transfers the input coordinates to a central processing system. If the computer system is in a power down mode, the touch screen controller asserts a main power on signal to a power subsystem, which causes the power subsystem to supply power to the central processing system according to the touch input.
