Abstract
An electronic device includes a power supply, a power consuming module, and a power control module. The power control module includes a capacitor, a detecting unit, and a control unit. A first end of the capacitor is connected to the power supply. Another end of the capacitor is grounded. The control unit includes a switching element. When the electronic device is powered on, the detecting unit controls the switching element to turn off, and the power supply supplies power to the power consuming module to charge the capacitor. When the electronic device is powered off, the capacitor discharges to supply power to the power consuming module. The detecting unit detects whether data storage of the electronic device is completed. When the data storage is completed, the detecting unit controls the switching element to turn on, causing the capacitor to discharge to ground. A power control module is also provided.
