Abstract
A dual voltage switching circuit includes a first resistor and two transistors. Each transistor has a first terminal, a second terminal, and a third terminal. The first terminals are connected to a control terminal of a computer. The second terminals are connected to a standby power supply of the computer. The third terminals are connected to a power-on terminal of the computer via the first resistor. When 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 form the standby power supply via the first resistor.
