Abstract
A CMOS clearing circuit mounted on a motherboard of a computer includes a south bridge chip and a switch member respectively mounted on the motherboard. The south bridge chip includes a reset terminal and an input terminal. The switch member is configured for controlling one of the reset terminal and the input terminal of the south bridge chip. If the switch member controls the reset terminal, the input terminal is disconnected from the switch member and the switch member is capable of controlling the reset terminal of the south bridge chip to be selectively connected to ground or a voltage source provided by the motherboard. If the switch member controls the input terminal, the reset terminal stays connected to the voltage source and the switch member is capable of controlling the input terminal of the south bridge chip to be selectively connected to ground or the voltage source.
