ABSTRACT:
A computer device includes a power managing controller coupled to a system controller, which in turn is coupled to an optical disk drive via an IDE bus, and operable in a normal mode, where electric power is supplied to the system controller, and a suspend mode, where electric power to the system controller is disrupted. A control key set is coupled to a keyboard controller that is coupled to the system controller and the power managing controller, and that is further coupled to the optical disk drive via a serial bus. The keyboard controller generates a control signal in accordance with operation of the control key set and received directly by the optical disk drive via the serial bus when the power managing controller operates in the suspend mode for controlling operation of the optical disk drive.
