Claim Text:
1. A power supply for providing the power consumed by a system having a plurality of electrical power consumption states including an active state and multiple power saving states, the system comprising a plurality of subsystems each having a plurality of subsystem power states including an active state and at least one power saving state, wherein a first subsystem has a plurality of power saving states, wherein the electrical power consumption states of the system correspond to respective different configurations of subsystem power states of the subsystems, and wherein the power supply provides a voltage to the first subsystem, wherein the first subsystem determines the state of the subsystem by a received non-zero voltage level and the first subsystem adjusts the state of the first subsystem based on detected increases and decreases in voltage level provided to the first subsystem by the power supply.
