Abstract:
1. A dual voltage switching circuit comprising: a first resistor; a first transistor comprising a first terminal, a second terminal, and a third terminal; and a second transistor comprising a first terminal, a second terminal, and a third terminal; wherein the first terminals of the first and second transistors are configured to connect to a control terminal of a computer, the second terminals of the first and second transistors are configured to connect to a standby power supply of the computer, and the third terminals of the first and second transistors are configured to connect to a power-on terminal of the computer via the first resistor and selectively connected to at least a peripheral device of the computer; upon the condition the first terminals receive a low level signal from the control terminal, the first and second transistors are on, and the power-on terminal receives a voltage from the standby power supply via the first resistor.
