Abstract
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.
Claims13
In combination, a computer system;
- a power state sub-system, operative to change the power state of the computer system, the sub-system having (a) a receiver operative to receive wireless control instructions and (b) a controller operative, in response to the received instructions, to change the power state of the computer system.
A method of changing the power state of a selected computer system of a plurality of computer systems, comprising generating a control instruction including a computer system identifier for the selected computer system, wirelessly transmitting the control instruction towards a receiver, and changing the power state of the selected system in response to the instruction.
A sub-system adapted to be responsive to a wireless command signal for controlling the power state of a computer system having a power supply, the sub-system comprising:
- (a) a power supply independent of the computer system power supply, (b) a receiver for the wireless command signal, and (c) a controller arranged to be responsive to the receiver receiving the command signal for deriving a control signal for a power state of the computer system.
In combination, a first computer system having an identification different from identifications of other second computer systems adapted to be in proximity with the first computer system, the first computer system having a power supply, a sub-system adapted to be responsive to a command signal for controlling the power state of the first computer system, the command signal including an indication of the identification of the first computer system, the sub-system including (a) a power supply independent of the first computer system power supply, (b) a receiver for the command signal, and (c) a controller arranged to be responsive to the receiver receiving the command signal for coupling a control signal for a power state of the first computer system to the first computer system, one of the power states of the computer system being lower than normal operating power of the computer system, the sub-system and first computer system being arranged so that the power state is changed only in response to the sub-system receiving the command signal including the identification indication of the first computer system.
A sub-system adapted to be responsive to a command signal for controlling the power state of a first computer system having a power supply, the first computer system having an identification different from identifications of other second computer systems adapted to be in proximity with the first computer system, the first computer system having a power supply and plural power states, the sub-system comprising:
- (a) a receiver for a command signal for controlling the power state of the first computer system, the command signal including an indication of the identification of the first computer system, (b) a power supply independent of the first computer system power supply, and (c) a controller arranged to be responsive to the receiver receiving the command signal for coupling a control signal for a power state of the first computer system to the first computer system, the sub-system being arranged to supply a signal to the first computer system for causing the first computer system power state to change only in response to the sub-system receiving the command signal including the identification indication of the first computer system.
