Abstract
A multiprocessor power-on switch circuit applied to a mainboard having multiple power-on circuits is provided, in which each power-on circuit includes a peripheral circuit corresponding to a processor. A selection circuit in the power-on switch circuit is responsible for selecting a power-on circuit as a first power-on circuit or a second power-on circuit. When the mainboard is powered on, a detection circuit in the power-on switch circuit receives a status signal from the first power-on circuit performing the power-on action. When the status signal is determined as a fault signal by the detection circuit, a control signal is output to the selection circuit, so as to make the selection circuit set the second power-on circuit as the power-on circuit to actuate the mainboard.
