Abstract
To provide a common apparatus power control system including: a multiple number of client apparatuses; a server apparatus; and a common apparatus connected to the multiple client apparatuses and the server apparatus via a network. The common apparatus performs communication with the server apparatus and acquires information on whether the power sources to all the client apparatuses on the network have been shut off, from the server. The common apparatus includes a power controller that controls the power mode of the common apparatus when the power to all the client apparatuses has been shut off.
Claims5
A common apparatus power control system comprising:
- a plurality of client apparatuses;
- a server apparatus;
- and,
- a common apparatus connected to the plural client apparatuses and the server apparatus via a network, characterized in that
- the common apparatus includes:
- a communicator for performing communication with each of the client apparatuses and the server;
- an acquisitor for acquiring information on whether the power sources to all the client apparatuses on the network have been shut off, from the server via the communicator;
- and,
- a power controller that controls the power mode of the common apparatus when the acquisitor obtains the information that the power to every client apparatus is shut off.
A common apparatus connected to a plurality of client apparatuses and a server apparatus via a network, comprising:
- a communicator for performing communication with each client apparatus and the server;
- an acquisitor for acquiring information on whether the power sources to all the client apparatuses on the network have been shut off, from the server via the communicator;
- and,
- a power controller that controls the power status of the common apparatus when the acquisitor obtains the information that the power to all the client apparatuses is shut off.
A method for controlling power of a common apparatus connected to a plurality of client apparatuses and a server apparatus, characterized in that the method includes:
- a communication step in which the common apparatus communicates with each client apparatus and the server apparatus;
- an acquisition step in which the common apparatus communicates information on whether the power sources to all the client apparatuses on the network have been shut off, from the server through the communication step;
- and,
- a power control step in which the common apparatus is controlled into a power-saving mode when the information representing that the power to all the client apparatuses has been shut off is obtained through the acquisition step.
