Abstract

The present invention relates to an electrical outlet device which cuts off the standby power of peripheral devices (such as a printer, a monitor, a speaker, etc.) when the power of a computer is turned off or when the computer is switched to a power-saving mode. The present invention also relates to a method for controlling the electrical outlet device. A conventional monitor serving as a peripheral computer device turns off the screen thereof to reduce power consumption when a computer is switched to a power-saving mode, wherein the conventional monitor then consumes approximately 15W. The conventional monitor stops the functioning thereof and is switched to a standby state when the power of the computer is turned off, wherein the conventional monitor then generally consumes approximately 4W. In addition, a printer consumes approximately 4W of power all the time. According to the present invention, the power being supplied to the peripheral computer devices is cut off when a computer is switched to a power-saving mode or when the power of the computer is turned off, thereby achieving zero power consumption and zero standby power without pulling out plugs, and completely preventing power consumption in the electrical outlet device of the present invention. As a result, electric charges are reduced, and the excessive emission of CO₂ caused by the unnecessary production of electric power is prevented to reduce environmental pollution.
