Embodiment Construction

[0010] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0011] Please refer to figure 1 , a power-on circuit is connected between the motherboard VGA connector 1 and the super input-output chip (SIO) 2 located on the motherboard. In this embodiment, the motherboard VGA connector 1 is connected to a display (not shown), and the The circuit is arranged on the main board, and uses the VGA connector 1 of the main board to realize the purpose of starting up. The following is a brief description of the VGA connector 1 on the motherboard:

[0012] Please refer to figure 1 , the motherboard VGA connector 1 has 15 pins. According to the VGA specification, the twelfth pin address code P12 of the motherboard VGA connector 1 receives a low-level signal and outputs it when the monitor is not powered on. When the power button of the monitor is pressed, the pin P12 receives a high-level signal and outputs it. ...
