Abstract
A host computer includes an enclosure, a motherboard mounted in the enclosure. The motherboard includes a battery, a reference voltage generating circuit, an electronic switch, an alarm unit mounted on the enclosure, and a comparator. The reference voltage generating circuit generates a reference voltage. The comparator is connected to the battery and the reference voltage generating circuit to receive the reference voltage and detect a voltage of the battery. The comparator compares the detected voltage of the battery with the reference voltage, and outputs a control signal to turn on the electronic switch to start the alarm unit when the voltage of the battery is less than the reference voltage.
