Abstract
A power consumption control method for collectively controlling the power consumption of electronic apparatuses connected to a network is provided. When an electronic apparatus is connected to the network, a management device performs power-saving control for the electronic apparatus. When the electronic apparatus is disconnected from the network, the electronic apparatus performs the power-saving control for itself. Thus, the power consumption of the clients connected to the network can be effectively reduced.
Claims29
A method of controlling power consumption of an electronic apparatus connectable to communicate over a network with a management apparatus, wherein
- the management apparatus performs power-saving control for the electronic apparatus based on status information constantly supplied from the electronic apparatus when the electronic apparatus is connected to the network;
- and
- the electronic apparatus performs the power-saving control for the electronic apparatus itself, based on power-saving control information stored in the electronic apparatus, when the electronic apparatus is disconnected from the network.
An electronic apparatus to be connected to a management apparatus via a network, said electronic apparatus comprising:
- a status table which describes status information of the electronic apparatus;
- and
- a power-saving control unit which constantly supplies the status information of the electronic apparatus to the management apparatus via the network, and performs power-saving control in accordance with power-saving control information generated by the management apparatus based on the current status of the electronic apparatus and supplied from the management apparatus via the network, when said electronic apparatus is connected to the network.
A management apparatus to be connected to an electronic apparatus via a network, said management apparatus comprising:
- a power-saving control unit which constantly receives status information from the electronic apparatus to detect a current power consumption status of the electronic apparatus, generates power-saving control information instructing a next power consumption-status of the electronic apparatus among predetermined power-saving modes based on the detected status, and then transmits the power-saving control information to the electronic apparatus via the network.
A computer-readable recording medium which stores a program to be executed by a computer built in an electronic apparatus connectable for communication over a network with a management apparatus, the program causing the electronic apparatus to constantly transmit status information indicating a power consumption status of the electronic apparatus to the management apparatus, and controlling a power consumption status of the electronic apparatus in accordance with power-saving control information supplied from the management apparatus in response to the status information of the electronic apparatus, when the electronic apparatus is connected to the network.
A computer-readable recording medium which stores a program to be executed by a management apparatus, the program causing the management apparatus to receive status information constantly supplied from an electronic apparatus when the electronic apparatus is connected to the management apparatus, to detect a current power consumption status of the electronic apparatus from the status information, to generate power-saving control information instructing a next power consumption status of the electronic apparatus, and then to transmit the power-saving control information to the electronic apparatus.
A method of controlling power consumption of an electronic apparatus connectable to communicate over a network with a management apparatus, comprising:
- determining whether the electronic apparatus is connected to the network or is disconnected from the network;
- when the electronic apparatus is connected to the network, the electronic apparatus constantly supplying status information to, and the management apparatus receiving the constantly supplied status information from, the electronic apparatus;
- the management apparatus performing power-saving control for the electronic apparatus;
- and
- when the electronic apparatus is disconnected from the network, performing power-saving control for the electronic apparatus by the electronic apparatus itself.
A memory medium storing a computer program controlling a computer, built in an electronic apparatus which is connectable for communication over a network with a management apparatus, by:
- determining whether the electronic apparatus is connected to the network or is disconnected from the network;
- when the electronic apparatus is connected to the network, the electronic apparatus constantly supplying status information to, and the management apparatus receiving the constantly supplied status information from, the electronic apparatus;
- the management apparatus performing power-saving control for the electronic apparatus;
- and
- when the electronic apparatus is disconnected from the network, performing power-saving control for the electronic apparatus by the electronic apparatus itself.
