Embodiment Construction

[0015] A method for controlling the power supply of a mouse and a keyboard. The power supply of the mouse and the keyboard is directly provided by the power supply of a computer host computer. The output part of the PC power supply is connected with the input part of the power supply of the mouse and the keyboard. Instructions from the display IC control section and supply power to the mouse and keyboard power input section. Specific steps are as follows:

[0016] 1) The mouse, keyboard and audio signals from the computer are sent to the computer signal processing chip; the video signal is sent to the main control chip after switching control with the D-Sub signal;

[0017] 2) The PC power supply receives the instructions from the display IC control unit and supplies power to the mouse and keyboard;

[0018] 3) The mouse, keyboard and signal processing IC start at the same time.

[0019] In the present invention, keyboard and mouse power supply 5V are provided by PC instead ...

Abstract

The invention discloses a method for controlling a power supply of a mouse and a keyboard, the power supply of the mouse and the keyboard is directly provided by the power supply of a computer mainframe, and the specific steps are as follows: signals of the mouse, the keyboard and the audio from a computer are transmitted to a signal processing chip in a display; video signals and D-sub signals are controlled by a switch and then transmitted to a main control chip; a PC power supply receives a command of an IC control part of the display and provides the power supply to the mouse and the keyboard; and the mouse, the keyboard and the signal processing IC are started simultaneously. The computer mainframe directly provides the power supply to the keyboard and the mouse and can lead the PC to be synchronous with the keyboard and the mouse.

Description

technical field [0001] The invention relates to a mouse and keyboard power supply in a computer, in particular to a control method for the mouse and keyboard power supply. Background technique [0002] At present, the power supply of the existing display is provided by itself, and the power supply of the PC and the display does not interfere with each other. When the monitor is connected with an external mouse and keyboard, the 200V power supply provides power to the monitor, and the control IC in the monitor controls whether to supply the 5V voltage of the monitor power board to the keyboard and mouse connected to the monitor, see figure 1 . When the computer enters the dormancy state, the power supply of the keyboard and the mouse are all turned off, and the PC has no signal input simultaneously. When using the mouse and keyboard to activate from the dormant state, the normal use of the mouse and keyboard will be affected due to the out-of-synchronization of the mouse an...
