Abstract: A method for monitoring a burn-in procedure of an electronic device is performed by a host computer, an external storage device, and a display device. The external storage device stores the burn-in procedure and a monitor procedure. The host computer copies the monitor procedure to the at least one electronic device and activates the monitor procedure. The monitor procedure activates the burn-in procedure for the electronic device and determines a state of the burn-in procedure. The monitor procedure then outputs a monitor result corresponding to the state of the burn-in procedure into the display device. The display device displays the monitor result.
