ABSTRACT:
A system for reducing power consumption of a computer peripheral device connected to a host computer during periods of inactivity of the host computer has a dedicated input for initiating power management operations. When the dedicated input is sensed a timer is started and a power management command is sent to the peripheral device, initiating a reduced-power mode other than off. In a preferred embodiment the system also starts a timer when the dedicated input is sensed, and after a predetermined time a second power management command is sent triggering a second reduced-power mode for the peripheral. The system is adapted to peripheral devices such as video displays and printers.
