US 2010/0250983 A1 · POWER SAVING CONTROL SYSTEM

Abstract

A power saving control system includes a power supply, a voltage conversion unit, an electrical switch, a control chip having a general programmable input output (GPIO) pin and a basic input system (BIOS) chip. The power supply is configured for supplying a voltage. The voltage conversion unit is connected to the power supply to receive the voltage and configured for converting the voltage into a working voltage of an electronic element, and outputting the working voltage. The electrical switch is connected between the voltage conversion unit and an input terminal of the electronic element. The control chip is connected to the electrical switch. The BIOS chip is connected to the control chip to control the electrical switch to be turned on or off via controlling an output value of the GPIO pin of the control chip to control the electrical element to work.
