Abstract

A computer system has a power supply including switched and unswitched power nodes supplying the appropriate DC voltages for the computer system's internal circuitry. Portions of the computer system's internal circuitry for receiving external communications are coupled to the unswitched power node. Other circuitry is coupled to the switched power node. Responsive to a request from a remote computer, switching circuitry enables power through the switched nodes, thereby powering the computer system. The switching circuitry can enable the switched power node responsive to a signal from an external device, such as an external modem, or through a signal generated by internal communications hardware.
