    • 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.
    • 电压调节电路在接收到来自南桥芯片的控制信号之后,转换第一电压并将转换的第一电压提供给北桥芯片的第一电压引脚。 北桥芯片的第二电压引脚连接到用于接收第二电压的电压转换电路。 逻辑控制电路接收来自超级I / O芯片的控制信号,并输出第一控制信号以接通开关以将第一和第二电压引脚连接在一起。 逻辑控制电路还向电压调节电路输出第二控制信号,以控制电压调节电路停止向北桥芯片的第一电压引脚提供转换的第一电压。 电压转换电路经由开关将第二电压提供给北桥芯片的第一电压引脚。
