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.

24. The computer-readable recording medium storing a program to be executed by a management apparatus to control a common apparatus connected thereto via a network by:

detecting an accessed state to the common device by the electronic apparatus; and

rearranging components contained in the common device so as to control an operational state of the common device based on the currently detected accessed state.

25. The recording medium as claimed in claim 24, wherein the program comprises:

a usage frequency detecting procedure for detecting how often the common apparatus is used by the electronic apparatuses; and

a common apparatus control procedure for controlling an operation of the common apparatus in accordance with the detected usage frequency.
