Abstract

A computer system having a CPU, a power management processor, a switch, a modem, a timer, an override circuit, a glitch circuit, and a power supply in circuit communication. 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.
