摘要： A computer system includes a power supply, a mainboard, and a restart control circuit. The power supply includes a system power source output and a stand-by power source output. The restart control circuit has a first input connected to the system power source output, a second input connected to the stand-by power source output, and an output connected to the mainboard. During an interval of time after the computer system is turned on, the system power source output provides working voltage for the restart control circuit, and the output provides trigger signals at a high level for the mainboard. During an interval of time after the computer system is turned off, the stand-by power source output provides stand-by voltage to the restart control circuit, and the output provides trigger signals at a low level for the mainboard to trigger the computer system to restart.
