Abstract
The device for testing a motherboard includes a power adapter, a first DC-DC converter, and a microcontroller. The power adapter converts an AC input voltage to a DC supply voltage. The DC-DC converter converts the DC supply voltage to a DC voltage at a channel coupled to the motherboard, and adjusts a voltage level of the DC voltage in response to a control signal. The DC-DC converter is enabled according to an enable signal. The microcontroller is configured to provide the control signal and the enable signal, and to determine whether a power on/off operation of the motherboard is normal. The microcontroller is configured to perform a test procedure on the motherboard to obtain a workable voltage range of the motherboard. The voltage level of the DC voltage in the test procedure is dynamically adjusted within a predetermined range around a nominal voltage value of the DC voltage.
