Abstract
A voltage regulating circuit converts a first voltage and provides the converted first voltage to a first voltage pin of a north bridge chip after receiving a control signal from a south bridge chip. A second voltage pin of the north bridge chip is connected to a voltage converting circuit for receiving a second voltage. The logic control circuit receives a control signal from the super I/O chip and outputs a first control signal to turn on the switch to connect the first and the second voltage pins together. The logic control circuit also outputs a second control signal to the voltage regulating circuit to control the voltage regulating circuit to stop providing the converted first voltage to the first voltage pin of the north bridge chip. The voltage converting circuit provides the second voltage to the first voltage pin of the north bridge chip via the switch.
