Title: Error indication circuit

Abstract: An indication circuit is used on a motherboard. First and second pins on the motherboard output different signals corresponding to different power-on self-test errors. The indication circuit includes first to third electronic switches, first and second light-emitting diodes, and first to fifth resistors. When different errors occurred during power-on self-test, different signals are output from the first and second pins on the motherboard, such that to make the first and second light-emitting diodes activated or deactivated. As a result, the indication circuit can indicate different errors when the motherboard is performing power-on self-test.
