Abstract

An electronic device includes a chassis with a power button and a motherboard. The motherboard includes a slot, a controller chip, a startup circuit coupling to the power button, and a protecting circuit. The protecting circuit includes an electronic switch and an AND gate circuit. The electronic switch includes a first terminal coupled to the slot, a second terminal coupled to a ground, and a third terminal coupled to a first power supply through a first resistor. The AND gate circuit includes a first input end coupled to the first power supply, a second input end coupled to the controller chip, and an output end coupled to the startup circuit. The power button is pressed down, the controller chip outputs a control signal with a high voltage to the second input end of the AND gate circuit.
