That is, the server administrator can collectively manage the standby power and / or the power consumption of the client PC, and the user of the client PC can individually manage the standby power and / or the power consumption of the client PC.

The server 60 according to the embodiment of the present invention can remotely monitor the client PCs 10, 20, 30, 40, 50 and control the power consumption and / or standby power of the client PCs. For example, since it is necessary to control power consumption and / or standby power of client PCs in order to reduce power consumption wasted by client PCs, the server 60 remotely monitors client PCs, The power consumption and / or the standby power of the client PCs can be controlled by the standby mode switching and / or the PC power shutdown.
