1. An electronic device, comprising:
- a power supply;
a load;
a voltage converting module connected to the power supply;
a switching module capable of cutting off an electrical connection between the power supply and the voltage converting module; and
a control module connected to the switching module and the power managing module;
wherein when the switching module is turned on, the voltage converting module is powered by the power supply through the switching module and outputs a working voltage through the switching module and the control module is powered by the working voltage;
when the switching module is turned off, the voltage converting module stops outputting the working voltage and the control module is disabled.

Abstract
An electronic device comprises a power supply, a load, a switching module, a voltage converting module, and a control module. The switching module establishes an electrical connection between the power supply and the voltage converting module when the electronic device is powered on. The voltage converting module is powered on through the switching module and outputs a working voltage. The control module is thus powered on. When the electronic device is powered off, the switching module is turned off, the voltage converting module stops outputting the working voltage, and the control module is disabled.
