Abstract: The present invention relates to a computer system having a CPU, a power management processor, a switch, an external signal reception means such as a modem, a timer, and a power supply in circuit communication. Optionally the system may also include an override circuit and a glitch circuit. The power supply has several power supply states, which are controlled by the power management processor responsive to the CPU, the switch, the modem, the timer, the glitch circuit, the override circuit, and the power management processor itself.

Abstract: The present invention relates to a computer system having a CPU, a power management processor, an external signal reception means such as a modem, and a power supply in circuit communication. The power management processor controls the regulation of power to the CPU by the power supply. In preferred embodiments, responsive to a ring signal having a frequency in a predetermined range being detected by the power management processor, the power management processor causes the power supply to provide regulated power to the computer system. Thereafter, the CPU preferably confirms that a ring signal was present by querying the modem to determine whether the modem also detected a ring. If so, the system remains powered. If not, the CPU causes the power management controller to cause the power supply to cease providing regulated power.
