A test device for testing a startup function of an electronic device, the test device comprising:

• an alternating current (AC) input port configured to connect to an AC power source;
• an AC output port configured to connect to a power port of the electronic device;
• a switch unit connected between the AC input port and the AC output port, and configured to establish a connection between the AC input port and the AC output port, or cut off the connection between the AC input port and the AC output port;
• a first universal serial bus (USB) port comprising a voltage pin, data pins, and a ground pin, wherein the first USB port is configured to connect to a second USB port of the electronic device and obtain a voltage from the second USB port when the electronic device is started up completely;
• a startup control unit connected between the switch unit and the first USB port, and configured to turn on the switch unit after the electronic device is turned off for a predetermined time, so that the AC power source powers on the electronic device;
• and
• a power on maintaining unit connected between the switch unit and the first USB port, and configured to maintain the switch unit to turn on when receiving the voltage from the first USB port after the electronic device has been started up completely.
