摘要： An electronic device receives a voltage from a power supply. The electronic device includes a load, a first adjusting module, a switching module, a delay module, and a second adjusting module. The first adjusting module produces a working voltage when the electronic device is powered on. The switching module establishes an electrical connection between the first adjusting module and the load when receiving the working voltage, and cuts off the electrical connection when not receiving the working voltage. The delay module delays outputting the working voltage to the load for a first predetermined time period on power on, and maintains a power supply to the load for a second predetermined time period after power off. Both the first predetermined time period and the second predetermined time period are independently adjustable.
