A microcontroller (MCU) and method controls a power indicator. The MCU reads an input voltage of a power supply device, reads an output voltage of the power supply device, and reads a power of the supply device. The MCU determines if the read input voltage of the power supply device falls within a predetermined input voltage range, determines if the read output voltage of the power supply device falls within a predetermined output voltage range, and determines if the read power of the power supply device falls within a predetermined power range. The MCU controls the power indictor to indicate a light according to a determination result of the power supply device.
