The computer terminal 10 basically comprises a computer main body and a monitor. The computer terminal 10 is configured to reduce power consumption based on state change setting request information provided from the service providing server 300, Such as the resolution or the refresh rate of the display device. In this case, since the amount of power consumed by the computer terminal 10 is reduced to a certain level, the power event state such as the overload state of the corresponding power control socket 100 can be switched to the normal state. At this time, the power control outlet distinguishes the overload warning level and the overload limit level with respect to the power consumption amount as one of the power events, and provides the overload information to the service providing server through the outlet management device, Or to shut off the power supply to the computer terminal coupled to the power control outlet when it reaches the overload limit level.
