Computer capable of realizing USB (Universal Serial Bus) keyboard starting

Abstract

The invention discloses a computer capable of realizing USB (Universal Serial Bus) keyboard starting. A micro-control chip with a USB interface and a USB change-over switch chip are increased, the twochips and the improved USB interface are all supplied with power through a standby power supply module so as to keep that the two chips and the improved USB interface are electrified when a computeris shut down, and the USB keyboard is inserted into the improved USB interface. When the computer is shut down, the micro-control chip with the USB interface controls the USB change-over switch to connect the USB keyboard to the micro-control chip with the USB interface; after the micro-control chip with the USB interface is electrified, the USB keyboard is initialized, a certain button is definedas a power button, and then, monitoring is carried out; and when the power button is pressed down, the micro-control chip with the USB interface outputs a starting signal and starts a mainboard working power supply module for starting, meanwhile, the micro-control chip with the USB interface controls the USB change-over switch to switch the USB keyboard to the USB controller of a CPU (Central Processing Unit), the control power of the keyboard is given back to the mainboard CPU, the mainboard CPU initializes and uses the USB keyboard again in an electrifying BOOT process, and USB keyboard starting and transferring work is finished.

Description

technical field [0001] The invention relates to a computer for realizing booting of a USB keyboard. Background technique [0002] If a computer with a large chassis is placed under a table or a small computer (including a cloud terminal) is hung behind a monitor, it is very inconvenient to find the power switch of the computer and turn it on by bending over or standing up. The present invention improves the circuit design of the mainboard of the computer, and adopts a method of combining software and hardware to realize the function of "keyboard one-key power-on" when pressing a certain key designated by the USB keyboard, allowing the user to control the computer while maintaining a sitting posture. The computer is turned on. [0003] The current solution is to add an external "computer power-on extension cable" device, such as the domestic patent number: CN201621454508.X, "a computer power-on reset extension module". , also clutters the countertop.
