Test device

A test device for testing a system comprising a first interface circuit, a second interface circuit and a power switch, wherein the test device comprises:

• a power supply, comprising:
• a supplying unit for providing a test power signal according to a wall wart signal;
• and
• a switch controller for periodically enabling the power switch to power the system with a test power signal in response to a control signal, wherein the system is enabled in response to the test power signal and boots up a system according to an operation system data provided via the first interface circuit;
• a status detector coupled to the second interface circuit for generating a status detection signal indicating whether the system boots up successfully in response to an operation signal on the second interface circuit;
• and
• a controller for providing the control signal and processing the status detection signal provided by the status detector.
