Power state sub-system and a method of changing the power state of a selected computer system

摘要

A power state sub-system changes the power state of a computer system associated with the sub-system. The sub-system has (1) a wireless receiver responsive to control instructions including IDs for plural different computer systems and (2) a controller that changes the power state of the system associated with the sub-system in response to the instruction having the ID for that associated system. The sub-system is powered independently of the computer system, so its ability to receive control instructions is unaffected by the system's power state.
