As soon as the power cord plug of the computer is plugged into the socket, if there is a power switch, it will be turned on, and the power supply of the host computer will start to work: power-on-rectification-charging, filtering capacitor filtering ... until there is normal voltage output, which takes some time. Your mainframe may have been powered on for too long. You use the mouse to turn off the computer without turning off the power. The main power supply has been working, so there is no waiting time when it is turned on again.

You press the power-on key of the host, and the motherboard starts to detect the voltage signal of the power supply. If the voltage is normal, it will send a power-on command and the motherboard will start working. Bios self-check-the first boot device is running-the hard disk reads windows-the boot startup item is started-the ip…… is searched ..........................................................................................................................................

Many people don't know that after the mouse is turned off, the host power supply still works normally. There is no power switch, and the power plug never pulls out. I don't know how much strength and life have been wasted.
