Abstract
An electronic device includes a switching circuit, a hardware (HD) indication unit, a LED module, a software (SF) indication unit, a first control switch electrically connected between a power port, an anode of the LED module, and the HD indication unit, and a second control switch connected between a cathode of the LED module, the SF indication unit and ground. When the electronic device is charged in a powered off state, the cathode of the LED module is grounded, the HD indication unit directs the first control switch to turn on and off alternatingly, and the LED module flashes accordingly. When the electronic device is charged in a powered state, the anode of the LED module is at a high voltage level, and the SF indication unit directs the second control switch to turn on and off alternatingly, and the LED module flashes accordingly.
