Keyboard introduction:

Keyboard is an instruction and data input device for operating computer equipment, and also refers to a set of function keys (such as typewriter and computer keyboard) arranged by the system for operating machines or equipment. The keyboard is also a part of the musical instruments that make up the keyboard. It can also refer to musical instruments that use keyboards, such as piano, digital piano or electronic organ. The keyboard helps to practice typing.

Keyboard is the most commonly used and main input device. You can input English letters, Chinese characters, numbers, punctuation marks, etc. to the computer through the keyboard, thus sending commands and inputting data to the computer. There are also some keyboards with various shortcut keys. With the passage of time, independent products with various quick functions are gradually sold in the market, with special drivers and setting software, and personalized operation can also be realized on compatible computers.

How to clean the dust on the computer keyboard

The common bacteria on computer keyboards are Streptococcus, Pseudomonas aeruginosa, Chlamydia trachomatis and so on. If not cleaned up in time, it will lead to digestive tract diseases, skin diseases and eye diseases. However, due to the large number of keyboard keys and complex structure, many people can't correctly master the cleaning method of the keyboard. I have sorted out the method of cleaning the dust on the computer keyboard, welcome to appreciate and learn from it.

1. First, turn the keyboard upside down and shake it gently. At this time, you will find scraps of paper, hair, food scraps and other sundries falling from the gap between the keys of the keyboard.

2. Take out the vacuum cleaner and remove the dust on the keyboard surface; Then using high-pressure air sprinkler irrigation to remove impurities in the gaps between keys; The side of each keycap of the keyboard is close to the bottom of the keycap, which is not easy to clean. At this time, you can use cotton swabs or chopsticks wrapped in cotton to wipe them one by one. Be careful not to touch too much detergent or water.

3. Finally, wipe the plastic shell of the keyboard and the surface of the keycap with a rag.

If you often stay up late in front of the computer, it is estimated that there are all kinds of things hidden in your keyboard, and the above methods may not be effective. You'd better take the keyboard apart and clean it thoroughly. However, due to the good sealing of the existing keyboard, dust and debris generally do not enter the keyboard, so I suggest you remove all the keycaps and remove the places covered by the keycaps. The method is as follows:

① Draw the layout of keyboard keys to avoid installation errors after disassembly;

② Remove all key caps. Pay attention to uniform force when disassembling, and do not use brute force. Please pay special attention to the enter key. Shift key, Ins key and+key in the keyboard area. Because the key is relatively large, there is an iron hook fixed under the key cap. Don't use too much force to deform the hook when removing it. In particular, the Enter key in the main keyboard area is fixed with two iron hooks below, and you can't pull it hard when you remove it. There is a small spring under the space bar. Be careful not to lose it when disassembling.

③ After all the keycaps are removed, you can see the sundries hidden in the keyboard. After the keyboard was removed, I found a lot of dust, fluff, hair, melon seeds and stains on the drink. Clean up these sundries with a brush first, then dry them with a rag dipped in water and wring them out. For those sticky stains, wipe them with a rag dipped in cleaning solution. Keycaps can be cleaned one by one with a rag, but it takes some time and patience to clean more than 100 buttons one by one.

(4) After all scrubbing, let these parts air-dry and you can install them. The installation of the keyboard can be completed according to the layout drawing above. Same as when disassembling, the force should not be too great, but even. For keys with iron hooks on the bottom, such as Enter key, hang the iron hooks first, and then install the keycap. Be careful not to install several arrow keys in the wrong position, and don't confuse the numeric keys in the keypad with the numeric keys in the keypad (the numbers of the numeric keys in the keypad are marked above the keys).

The washed keyboard is brand new. Working with a clean keyboard may give you more inspiration.

How to clean the dust of computer graphics card?

Video memory is short for display memory. Its main function is to temporarily store the data to be processed by the display chip and the processed data. The stronger the performance of the graphics core, the more video memory is needed. In the past, the main memory was SDR, and the capacity was not large. Most graphics cards on the market use DDR5 memory. Once there is dust on the graphics card, it is easy to affect the heat dissipation.

Next, let's take a look at the precautions for washing graphics cards.

In fact, players with certain qualifications are no strangers to washed graphics cards, but they really dare to do very little, mainly because they are afraid that the graphics cards will be scrapped after washing. Through the experimental conclusion, we know that this kind of worry is unnecessary, and it is actually very safe to wash the graphics card. Let's introduce how to wash the graphics card together.

One thing to note is that water-washed graphics cards must choose pure water with less impurities, weak conductivity and even less than electricity. Experimental tests show that tap water also meets the requirements. Of course, friends who are afraid of problems with the graphics card can buy a few bottles of pure water to clean it.

First, let's see how to clean the video card with tap water:

In order to dispel everyone's concerns, we must first test whether the tap water is conductive. A multimeter is needed here, mainly to test the resistance value of water with a resistance file. The smaller the value, the stronger the conductivity. The value of 1 means that the resistance value is infinite, which means that it is not conductive or the conductivity is extremely low.

Using multimeter to measure the resistance of water, the value is infinite, indicating that the resistance of tap water is very high, the impurity content is very low, and the conductivity can be ignored. Because tap water is treated and filtered, there are generally few impurities, which also leads to the weak conductivity of tap water. If you change to river water or unclean water, you will find that the resistance of water is too small. It is recommended to clean the graphics card with pure water.

Through the above experiments, I believe that everyone's worries about washing graphics cards have been reduced a lot. Let's take a look at how to wash the graphics card.

1, the washed graphics card can be washed directly in water without special skills.

2. Wash the video card fan.

3. Remember to dry the graphics card after washing it with water. It is recommended that you put it in a ventilated place 12 hours or so, so that all the water in the cleaned graphics card will evaporate. Before getting on the computer, it is recommended to blow the graphics card with a hair dryer to ensure that the whole graphics card has been completely air-dried and there is no water residue, so as to avoid short-circuiting and burning the hardware after booting.

After the graphics card is cleaned and dried for a period of time, we can put it back into the computer. Conditional users suggest adding some roller oil to the rotating shaft of the video card fan to ensure a better rotating speed of the cooling fan. Finally, the graphics card was cleaned successfully and the computer worked normally. The important thing is that the stability of the graphics card is obviously better than before.

Through the above video card washing tutorial, I believe many friends are interested in video card washing. Washing graphics cards mainly pays attention to using water with less impurities, such as pure water or distilled water, which is basically non-conductive and tap water can pass the test. However, the general domestic water has certain impurities. When the impurity content in water reaches a certain level, it will conduct electricity when it meets current. So the main thing to pay attention to when washing graphics cards is the problem of water. In addition, many netizens read this and think about other hardware such as motherboards. Can I wash it? The answer here is no, because the motherboard is too precise, and there are many slots, so it is difficult to completely dry it after washing, so it is prone to motherboard damage, so washing hardware is actually more suitable for graphics cards.

The computer keyboard is dirty, how to clean it?

A special brush for computer keyboard appeared on the market, with long bristles, moderate hardness and unique shape. The brush head can penetrate into the keyboard seam, and the surface and interior can be scanned at the same time. Prices range from a few yuan to a dozen yuan according to the quality, and some computer shops will also give them away at random. It is very easy to clean the keyboard every day. There is also a transparent dust cover for the keyboard, which is both beautiful and dust-proof. You can also use a cotton swab dipped in alcohol to scrub the keyboard keys. For cracks that are difficult to clean, find a small stick, such as a toothpick. It is easier to wipe off the dust by wrapping an appropriate amount of absorbent cloth or soft paper and dipping it in alcohol. Of course, these are just routine maintenance. In order to be cleaner and safer, it is best to open the keyboard back cover every few months, take out the circuit board for deep cleaning, and thoroughly clean it with a soft cotton swab. However, you should be careful to avoid damaging the parts. If you are not sure, you can go to a computer store and find a professional to do it.

How to clean the keyboard

1, the easiest way to clean the keyboard is to tap the keyboard in turn before going to work every day to let the dust in the gap sway into the garbage basket.

2. You can also prepare a small brush in the office and carefully clean the dust and soot in the gap with the brush regularly.

3, the air pump can also help, you can put a small air pump of hydrogen balloons in the office, and you can use the air pump to blow out the dust in the keyboard every week to avoid accumulation.

In addition, there is a special keyboard vacuum cleaner with USB interface on the market, which can suck away the dust in the gap of the keyboard. Vacuum every three days to keep the keyboard clean and worry-free.

5. You can also prepare a small bottle of keyboard cleaner and wipe the keyboard surface with a cotton swab, which will neither corrode the keyboard surface nor harm the finger skin.

Extended data

Thoroughly clean

Thoroughly clean and disassemble the keyboard, and thoroughly clean the inside. If you are new to computers, it is recommended not to disassemble them directly.

Disassembling the keyboard is not only a physical activity, but also a technical activity. If it is not handled properly, the keyboard particles cannot be completely restored, and it is easy to damage the keyboard.

Note: If you use a waterproof keyboard, you can wash it directly with water.
