Abstract

A boot test apparatus and method can repeatedly execute actions of power-on and power-off for a cold boot test of a computer to test whether the computer is operable. The boot test apparatus includes a microprocessor, a controller, and a power switch. The microprocessor generates a control signal according to a period voltage provided by an internal power supply. The control signal includes a pulse signal and a voltage signal. The controller controls a power switch to send the pulse signal to the computer through a power button of the computer, and controls the power switch to send the voltage signal to the computer through a power input port of the computer. The microprocessor further obtains test information from the computer when the computer executes a cold boot process according to the control signal, and displays the test information on an LED when the cold boot process is abnormal.
