The computer has already become numeral to turn ages basic tool, the keyboard is without intermission arbitrarily pounded by the person, and the mouse is even held in center of palm of hand by prison ground in the prison.Also is to pass them, people just can carry on many tedious and complicated works, make the humanization of calculator consumedly strengthen and the operation also easily goes more in brief.If you own a keyboard with comfortable convenience vivid with one without extra trouble of mouse, the nature will make you be getting wither proficiency at the time of carrying on a calculator work and playing games.
This design research is the maintenance technique of keyboard and mouse, first from the cause of keyboard mouse, development, arrived their works principles to all have detailed introduction, the point analysis introduced the breakdown type of keyboard and mouse and support technique after do and have good and practical value.
The keyword, keyboard, the mouse, break down, maintenance

1 the single-chip microcomputer system is designed and applied single-chip microcomputer control technology with 8051 single-chip processor core control qingfeng 800 cubic meters of thermoelectricity corporation, the water tank, and realize the alarm and manual, automatic switching function. this system, convenient operation, good performance, compared with the production water control system of power plant. the paper also gives a detailed related hardware diagram and software flow chart, and the assembly language program. 2.

this system consists of scm system, matrix, led display and keyboard alarm system. system can accomplish lock, overtime alarm, super lock, administrators, modify user password decryption basic locks function. besides the basic function of locks, it has adjustable electrical storage, prompting sound, according to the actual circumstance also can add function of remote control. this system cost, function and practical

The computer has become the digital age basic tools, keyboard continually being arbitrary percussion, Mouse has also been firmly in the grip among palm. It is also through them, people can conduct many tedious and complicated work, the computer makes humanity greatly strengthened, more simple operation. If you have a comfortable keyboard and a flexible dig the click of a mouse, you will naturally work and conducting computer games when more handy. The study was designed keyboard and mouse maintenance skills, with the keyboard and mouse of the origin, development, their principle is described in detail, After the focus of analysis done on the keyboard and mouse types of faults and maintenance skills, has good practical value. Key words : keyboard, mouse, fault, maintenance
