摘要： A circuit includes a work-power module, an electronic component, a switching apparatus, and a power control unit. The power control unit includes an input pin connected to the work-power module, an output pin connected to the electronic component, and a control pin connected to the switching apparatus. The switching apparatus is capable of controlling the status of the power control unit. Upon the condition that the power control unit is turned on, the work-power module is capable of supplying power to the electronic component. Upon the condition that the power control unit is turned off, the work-power module is not capable of supplying power to the electronic component.

摘要： 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.
