ABSTRACT:
A computer system having a CPU, a power management processor, 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. 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 confirms that a ring signal was present by querying the modem 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.
