How many extra steps I thought and decided to make a so-called general shutdown device that the computer would control. Here is a diagram of this device. We can say in it only one detail - this is a relay for contact closure voltage of 5 volts, because it will be stuck in the usb port and on the contact group voltage of at least 400 volts and a current of up to 1 A.
