How to clean the keyboard?
The cleaning and maintenance of the keyboard is not complicated. The easiest way is to tap the keyboard in turn to let the dust fall out of the gap. Mr. Chen, who is in charge of computer hardware maintenance in a computer company, said that some of his colleagues often use computers while smoking, and soot often falls in the cracks of computer keyboards. To this end, he specially bought a small brush, regularly cleaned the dust and soot in the gap with the brush, and then wiped the surface of the keys with a cotton swab dipped in a special computer keyboard cleaner. It only took half an hour to make a keyboard look brand-new. According to reports, to clean the keyboard, you can also use the "balloon" to remove the dust on the mechanical watch and camera lens before cleaning. Teacher Chen reminded computer users to clean and maintain the keyboard after turning off the computer and unplugging the connecting plug, and the cleaning agent should use a special cleaning agent to prevent the metal parts of the keyboard from being corroded.
According to the author's understanding, a convenient and practical keyboard vacuum cleaner with USB interface has been introduced on the market for keyboard cleaning and maintenance. This vacuum cleaner does not need an external power supply, and there are two kinds of suction ports on the accessories: one is a relatively large caliber, which can suck some relatively large sundries; The other is composed of a brush and three smaller suction ports, which is convenient to suck away the dust in the keyboard while brushing your teeth, making the cleaning and maintenance of the keyboard more convenient.
interconnection
A survey on the sanitary condition of office equipment published by the University of Arizona shows that the number of microorganisms per square centimeter of computer keyboard is 5 10, while the number of microorganisms per square centimeter of toilet seat is less than 8 due to frequent disinfection. Compared with the two, the number of bacteria on the keyboard is nearly 64 times higher than that on the toilet seat. Because many computer users don't often clean and maintain the keyboard, the surface of the keys will often be stained with sweat, oil, saliva, dust, hair and other things of the computer users, which will be deposited in the gaps of the keyboard, hiding many germs. Some computer users suffer from various skin diseases, eye diseases and gastrointestinal diseases, which are also related to not paying attention to keyboard hygiene. Therefore, changing the bad habit of eating and smoking in front of the computer and keeping the keyboard clean are not only closely related to normal use, but also to our health.

The keyboard is the input device of the computer. Because it is exposed, and the gap between the keys of the keyboard is large, small sundries are easy to get into people and get dirty, which leads to the failure of the keys, so it should be cleaned frequently. If you want to know how to clean the keyboard thoroughly, come with me.
1. Remove the rear cover
First, unplug the keyboard plug from the mainframe and turn it over to see the fixing screws on the back. Unscrew all the screws at the back and you can take off the back cover.
2. Remove the circuit board and circuit film.
After the keyboard back cover is removed, the flexible circuit film can be seen. The structure of the circuit film is three layers. If there are sundries between the films, the keys will be invalid, so these three-layer circuit films are also our cleaning objects. There is no fixing screw on the three-layer circuit film, so it can be taken down directly. They are fixed through round holes in the film, and external screws are fixed on the front panel through round holes in the circuit film. The circuit board of the keyboard is not large, so it can be removed directly without screws. There are not many components on the circuit board, only a few circuit wires are connected. There are three indicators on the other side of the circuit board, namely "Num look", "Caps Lock" and "Seroll Lock" in the upper right corner of the keyboard.
3. Remove all the keys
After removing the circuit board and circuit film, you can remove all the keys. Each button has a separate rubber pad. Take them all off first. When all the rubber pads are removed, you can remove the key. The key is fixed with a plastic buckle and can be removed by pulling hard.
Thoroughly clean up
Now that all the detachable parts have been removed, they are ready to be cleaned. For the keyboard panel, you can brush off those tiny sundries with a brush first, and then wipe them clean with a cloth. The three-layer circuit film can also be cleaned in this way. Keys can be washed with water or scrubbed with special surface cleaning agents.
Put it back
After cleaning, it will be installed. One thing we need to pay attention to is to see if all the rubber pads are in their own positions to avoid dislocation when installing other parts. ...& gt& gt
