Desktop computer maintenance to avoid dust invasion
Computer is a high-tech precision electronic product, many computer hardware technology has reached the level of ultra-micro technology such as millimeters and microns. Due to the very strong penetration ability of dust, once the dust adheres to the delicate electronic components, it will adversely affect the operation of the components.
In order to prevent the computer from being invaded by dust, try to create a dust-free working environment. If conditions do not allow, you can also take some other measures, for example, put the computer in a ventilated location, cover the monitor and case with a dust cover, etc. In addition, users can also choose a case with a dust-proof design when purchasing a computer case.
Controlling temperature and humidity
The life of a computer is closely related to the aging of internal electronic components. Among various environmental factors, temperature and humidity are the main factors that accelerate the aging of components. Especially when the metal pins of electronic components are full of dust, the influence of oxygen in moisture and high temperature will greatly accelerate the oxidation and corrosion of metals.
Therefore, try to maintain proper temperature and humidity. Generally speaking, the temperature of the environment should be controlled between 5-35 °C, and it should be kept away from heat sources. The relative humidity of the environment should be controlled at 30%-80%. Too high humidity will affect the performance of computer hardware, and even short circuit will occur; too low humidity will easily generate static electricity, which will also cause hardware short circuit. In the hot summer or rainy season, if conditions permit, you can turn on the air conditioner or dehumidifier to avoid the normal use of the computer due to temperature or humidity problems.
Use a stable power supply
The AC power voltage used by the host should be maintained within the range of 220V±10%. And need to keep the power supply stable. If the ambient power supply is frequently disconnected (such as power failure), then for the sake of data security, it is recommended to equip the computer with a UPS (Uninterruptible Power System), so that the power supply can continue to be maintained in the event of a power failure.

How to use the notebook cleaning kit for laptop maintenance
1. First, use a brush to clean the periphery and corners of the LCD screen of the computer, and clean up those magazines and dust, and then use a paper towel to clean these magazines Wrap it up and throw it away.
2. Then put the screen cleaner spray on the soft cloth of the cleaning kit, and use it to wipe the computer screen. Because the computer screen is relatively large, it is best to wipe the computer clockwise with the same one, and then use it again. Wipe the part of the computer screen more completely, preferably 2 to 3 times, so that the computer screen can be completely covered by the cleaner.
3. It is best to wipe the computer screen again with a clean soft cloth to clean up all the detergent left on the computer screen. During the process of wiping words, it is best not to have skin. Do not touch the computer screen, because this will leave skin marks on the screen, which will affect the appearance of the screen, and you have to wipe it again.
Cleaning and maintenance methods
1. For those large dust stains attached to the surface of the laptop, use a soft soft brush or paper towel to clean up the large dust, from top to bottom or from left to left To the right, do not wipe back and forth across the surface.
2. For those relatively fine dust, use air blower and cleaning soft glue, because air blower and soft glue can clean those parts that are not easy to clean normally.
3. For some more stubborn stains, I am afraid you need to use a professional cleaner. Just spray a little on the stained area, and then wipe it hard with a cleaning cloth or wet towel.
4. To clean the interior of the notebook, it is relatively simple to disassemble the back cover of the notebook, just unscrew all the screws on the back. However, it should be noted that some models of laptops will have a bayonet around the back shell, and you need to use an opening pick. After removing the back cover, you can first blow away the larger dust with a hair dryer. Be careful not to use hot air.
5. In addition to removing most of the dust, use a soft toothbrush to remove the fine dust in the gap, especially the dust on the cooling fan is difficult to clean. Details+
All-in-one computer maintenance How to maintain the all-in-one computer
1. The maintenance of the all-in-one computer should pay attention to that the monitor shell or the cabinet shell should not be pressed against the touch area, so as to avoid the mouse being always at a certain point on the four sides of the monitor The phenomenon. In actual use, assuming that the cabinet casing is pressing against the touch area, you can slightly increase the distance between the cabinet and the display screen; assuming that the display casing is pressing the touch area, you can also try to screw the monitor casing. Take it easy.
2. For the cleaning of the touch screen. Generally speaking, the touch screen of a normally assembled interactive all-in-one machine needs to be cleaned once a year. Since it is assumed that the reflective stripes around the touch screen cover too much dust, the touch screen will gradually lose touch performance. Use glass cleaner or alcohol to spray on the towel, and then use the towel to wipe the surface of the glass. Regarding the dust between the gap between the front cover of the touch monitor and the touch screen, you can carefully clean it with a thin cloth strip on a business card or bank card sleeve. It is worth noting that, before cleaning, be sure to cut off the touch screen power. Moreover, because water droplets will seriously affect the response rate of the touch screen, for this reason, pay attention to keeping the screen dry when cleaning, and do not wipe it with water. For touchscreens used in places with high population density, it is best to wipe them with a clean cotton cloth before starting the machine every day.
The lifespan of an all-in-one computer is a few years.
The lifespan of an all-in-one computer is about 5 years. Desktops have the advantages of fewer connections, smaller size, higher integration, and no significant change in price. They can be shaped to be stronger, and manufacturers can design products with great personalities. All-in-one computers can be said to be an emerging product line alongside notebooks and traditional desktops.
So the lifespan of an LCD monitor like an integrated computer is 5-8 years, but it will be dark after 5 years. Since the display of the computer is LCD, the actual lifespan is about 5 years. In this way, the cost is very large, and the depreciation fee is 800 to 1,000 yuan per year. The desktop computer is only five or six hundred yuan a year, which is relatively much better. Details+
Tablet PC Maintenance 1. Heat Dissipation
Placing the Tablet PC on a soft object, such as a sofa on a bed, may block the cooling holes and affect the cooling effect, thereby reducing the operating performance, or even crashing.
2. LCD screen
(1) Do not touch the surface of the screen with sharp objects (hard objects) to avoid scratches.
