    • An electronic device including a power switch, a switch unit, a power supply unit and a control unit is provided. Two power ends of the power switch are connected in parallel with two connecting terminals of the switch unit. The power supply unit generates a system voltage by a power come from the power switch or the switch unit. When the two power ends of the power switch are conducted for a predetermined time, the power is provided to the power supply unit and the electronic device starts up. Furthermore, the control unit controls the switch unit to conduct the two connecting terminals, so that the power is still provided to the power supply unit through the switch unit after the two power ends are disconnected. When the electronic device is shut down, the control unit controls the switch unit to disconnect the two connecting terminals.
    • 提供了包括电源开关,开关单元,电源单元和控制单元的电子设备。 电源开关的两个电源端与开关单元的两个连接端子并联连接。 电源单元通过来自电源开关或开关单元的电源产生系统电压。 当电源开关的两个电源端进行预定时间时,电源被提供给电源单元并且电子设备启动。 此外,控制单元控制开关单元导通两个连接端子,使得在断开两个电源端之后,仍然通过开关单元将电力提供给电源单元。 当电子设备关闭时,控制单元控制开关单元断开两个连接端子。
