Title: System and method for testing an operating condition of LEDs on a motherboard

Abstract: A computer-implemented method for testing an operating condition of light emitting diodes (LEDs) on a motherboard includes assigning an LED identification for each LED according to positions of the LEDs on the motherboard, selecting a first LED identification for a first LED and a second LED identification for a second LED, setting the first LED in a bright state, the second LED in a dim state, and any remaining LEDs in a flicker state, and controlling the LEDs to operate. The method further includes determining whether the total count of the LEDs in the bright state is equal to one, and whether the total count of the LEDs in the dim state is equal to one, comparing the first LED identification input with the first LED identification, and comparing the second LED identification input with the LED identification, and reporting a comparison result.
