First, turn the machine on and off:
Computer equipment must be turned off correctly, otherwise it will affect its working life, which is the chief culprit of some faults.
The correct sequence of startup and shutdown is: turn on the computer, first turn on the power of the computer peripheral devices (such as monitors, printers, etc.). ), and then turn on the power of the computer host; The shutdown sequence is just the opposite. First, turn off the power of the host computer, and then turn off the power of other peripheral devices.
Second, the use of computer equipment safety instructions:
(1). Don't put computer equipment in dusty places (such as windows near the roadside). ). If you really can't change places, cover them with a dust cover when not in use; Don't put it in a damp place (such as a place where water bottles are concentrated or near a water dispenser, which is easy for people to splash water on the equipment). Pay attention to the heat dissipation of the main chassis to avoid direct sunlight on the computer;
(2) It is forbidden to use other electrical appliances, hand warmers and other personal electrical equipment on the computer special power socket, and check whether all computer equipment is turned off before leaving work;
(3) Don't move the computer while it is working;
(4) When the computer is working, don't plug and unplug the equipment, turn it on and off frequently, plug and unplug all interfaces (except USB interface) with electricity, which is easy to burn the interface card or damage the integrated block;
(5). Anti-static, anti-dust, can not let the keyboard, mouse and other equipment into the water;
(6) Back up the data regularly and tidy up the disk. Due to frequent use of hard disk, virus, misoperation and other reasons, some data are easily lost. Therefore, it is necessary to back up some important data frequently to prevent all the work completed in a few months from being lost because the backup is not timely. Regularly arrange disks and clean up junk files in time to avoid junk files occupying too much disk space and bringing inconvenience to the search and management of normal files. Not only can you easily delete important files, but you can also use them in an emergency.
(7) If any problems are found, they should be reported for repair in time, so that the machine can always work in good condition, including whether there are abnormal problems in the equipment and whether the wiring is loose.
(8) Prevent computer viruses, install anti-virus software and upgrade anti-virus regularly.
Some points for attention when using a computer:
1, automatically link to some strange websites.
Pay attention when surfing the internet, don't mess with things you don't understand, especially pornographic pictures and advertisements floating in some browser pages, and don't click on them; If it affects your browsing, please drag the slider up and down until you reach the best angle.
In addition, try not to install some Internet plug-ins, Internet assistants and their toolbars, which will sometimes affect the normal use of the browser.
2. Don't download and install some small software or programs online.
3. Mail from strangers.
Receive emails from strangers, especially those with attractive titles, such as a joke or a love letter, and attachments.
4. Check the virus before using the USB flash drive, and regularly check the system for viruses with anti-virus software.
Common manifestations of computer virus attacks;
1, the running speed is obviously slow;
2. In the past, the normal running software often had the error of insufficient memory;
3. Prompt some irrelevant words.
4. Produce specific images.
Nothing was done, and the hard disk light kept flashing.
6. The 6.Windows desktop icon has been changed.
7. The computer suddenly crashes or restarts.
8. Send email automatically.
9. The mouse is automatically busy.
Possible adverse consequences of computer virus:
1, hard disk cannot be started, and data is lost.
2. The system file is lost or destroyed.
3. The file directory is chaotic.
4. Some files are lost or destroyed.
5. Some documents will be automatically encrypted.
6, network paralysis, unable to provide normal services.
Question 2: What should a novice pay attention to when using a computer? Ten rules for computer beginners
For a computer beginner, computer operation is very complicated, including many troublesome steps such as booting, software installation and system setup. If you want to have a stable and efficient computer operating environment, please master the following ten rules first, so as to keep up with the crisis and turn the tide.
First, make a system startup disk: After the computer gets it, the first thing to do is to make a system startup disk that can drive the CD-ROM drive immediately. Why do you want to make a system startup disk? Once the system is poisoned, damaged or the operating system needs to be reinstalled, nothing can be done without this small floppy disk. Making a common system startup disk is very simple. Just take a /S parameter when formatting the floppy disk, but if you want to start the CD-ROM drive with this startup disk, it will take some time. In the past, genuine Windows95 came with its own startup disk, and the CD-ROM driver was stored in it, but it seems that it can't be applied to all kinds of computers, and it often happens that the CD-ROM driver can't be found. However, the system startup disk made by Windows98 can be trusted now.
Second, carefully keep the drive disk: when the computer is moved home, there must be a lot of instructions, warranty certificates, and floppy disks or CDs of various hardware drivers and application software. The most important thing is that these floppy disks and CDs are files that must be used when installing the sorting system. Without them, your computer can't drive peripheral hardware or other storage devices, and it will be disabled. Don't put them anywhere or for other purposes. Check them carefully. Ordinary floppy disks are prone to failure due to moisture, so it is best to back up the software in them to hard disks or other storage devices, and then put the original disks into moistureproof box for storage. Suggestion: If possible, it is a good method to burn important programs and software to CD for backup.
Third, don't mess up in times of crisis: just because the computer suddenly doesn't respond during operation doesn't mean it must be pawned. Ordinary people are generally excited, desperately tapping the keyboard and mouse, pressing CTRL+ALT+DEL without waiting for a few seconds, or even pressing the reset button to force the computer to restart, and the data that can be saved at ordinary times will be swept away. The correct way is to press the button or mouse twice when the picture is frozen, and then wait for three to five minutes. By the way, observe the status of the hard disk indicator light on the computer casing. If the indicator light is still flashing occasionally, it means that the computer is not in a coma, but has temporarily lost its mind and should be able to return to normal after a while; If the indicator light stays on or off for three to five minutes, it may be a sign of good luck, and a forced restart is appropriate at this time. In fact, Windows95/98 is most afraid of pressing CTRL+ALT+DEL, so it is not appropriate to restart. A friend often complains to me that his system didn't do anything at random, but restarted after crashing. Why do you always die? In fact, this has a lot to do with the user's incorrect operation. Of course, there may be some problems with the computer itself. However, if the manufacturer gives you all kinds of tests and there are no problems, the user must bear the greatest responsibility, because after all, it is caused by himself. Why not improve his own usage? It should be noted that when you feel that the machine has crashed, you may wish to use the shortcut key ALT+F4 to forcibly close the window to see if it is feasible. If this cannot be undone, then consider pressing RESET or CTRL+ALT+DEL.
4. Don't treat loyal ministers as monsters: Some tools and software, most commonly anti-virus software or system maintenance programs, will start by themselves after being opened, knocking at places you can't see, and occasionally jump to the screen and desktop for a general cleaning when the time comes. At this time, as novices, don't think they are uninvited guests, stop their operation immediately, or even think they are poisoned and shut down forcibly, which will lead to unpredictable consequences. In addition to the above two types of software, there are many programs that like to engage in such underground activities, and suddenly a message pops up saying what to do. The starting point of this design is of course for users. > & gt
Question 3: What should I pay attention to when using a computer? Turn on and off the machine correctly, first turn on the monitor power supply and then turn on the host power supply, and vice versa when turning off the machine; Never turn off the phone by force.
Please place the computer carefully, away from high temperature, humidity and dust, and avoid direct sunlight.
Pay attention to lightning protection in summer. Don't use the computer when it thunders and rains. Better unplug the power cord.
Avoid the influence of magnetic field on the computer. Don't put it too close to TV, speakers, amplifiers and telephones, at least two meters apart.
To prevent cross-combustion, please equip the computer with a special anti-static wiring board.
Avoid humid environment. In the rainy season, turn on the computer that has not been used for a long time and run for a period of time; When the weather is dry, appropriately increase the indoor air humidity.
1, high temperature
The ideal working temperature of the computer is 10-35 degrees, neither too high nor too low is good. The damage of high temperature is mainly aimed at temperature-sensitive components, such as CPU. The working temperature of the CPU must not exceed 80 degrees, otherwise it is very easy to burn out the CPU. It is best to install temperature measurement alarm software. When using computers in summer, we should pay attention to indoor ventilation and cooling, and it is best to have air conditioning in rooms with computers.
2. Humidity
Humidity is also harmful to computers. General relative humidity is between 30% and 80%. If the humidity is improper, it is easy to cause short circuit. Therefore, when the air is too humid, be careful when driving. In addition, be sure not to use the computer with wet hands. On the contrary, it is not good to be too dry. Too dry is easy to generate static electricity, and it is also easy to harm the computer.
3. Power supply
Unstable power supply is actually a great harm in the process of computer use. Voltage instability or instantaneous high current can easily cause serious damage to the computer. The normal requirements of computers for alternating current are 220V and 50HZ. It is best to have a good grounding system, and it is best to use UPS.
4. Dust
Because the computer case is not completely closed, and static electricity will absorb dust, dust can easily enter the computer. When dust adheres to the surface of integrated circuits, it will cause poor heat dissipation, and in severe cases, it will cause short circuit. Optical drive, floppy drive and monitor are most afraid of optical drive. If too much dust is adsorbed on the optical head of the optical drive, it is easy to cause a sharp decline in the ability to read the disc. The damage of dust to floppy drive is similar to that of optical drive. In the monitor, too much dust is easy to burn the monitor. Accessories such as keyboards and mice are afraid of dust. So you'd better pay attention to dust the computer.
5. Vibration and shock
Hard disk, CD-ROM drive and floppy drive are all afraid of collision. The rotating disk is read by the optical head. If severely impacted, the disc will be scratched and the drive will be completely damaged. No computer user would want such a thing.
6. Static electricity
Static electricity has always been the killer of precision circuit boards. When static electricity accumulates to a certain extent, it will produce high-voltage discharge locally, which is easy to burn the circuit board. The simple protection method is to discharge the computer frequently, and it is ok to touch the machine with metal objects.
7. Radio
This killer is often overlooked. In fact, it is very harmful to the monitor and also interferes with the motherboard. When the external radio signal is strong, the electromagnetic field of the display will be seriously disturbed, and if the frequency is high, it will affect the normal working state of the display. Therefore, it is best to avoid radio interference when using computers.
Question 4: What should we pay attention to when using computers in our daily life? How do you answer this question? It's too general
Let me share some experiences first.
Try not to overload the computer, otherwise it will shorten its service life.
Don't put important files on the system installation disk (disk C).
Develop the habit of surfing the Internet healthily. Some websites will leave viruses in our computers.
The use environment should be dry and ventilated.
Question 5: What should I pay attention to when using computers in my daily life?
1, don't shut down illegally, which may cause the computer to fail to start.
2. Install antivirus software (don't install multiple antivirus software) to prevent the computer from being attacked by viruses.
3, restart immediately after shutdown, which is very harmful to computer hardware.
Don't delete the program in the folder directly, but uninstall it, otherwise there will be a lot of rubbish in the computer.
5, often clean up the garbage, run faster.
6. Regularly defragmenting the disk can improve the efficiency of the computer.
Question 6: What are the precautions when using a computer? (1) Be very careful when performing operations that may cause file damage or loss.
(2) After the system exits abnormally or loses power unexpectedly, the hard disk should be scanned as soon as possible and the errors should be fixed in time.
(3) When the computer is turned on, pay attention to the defense against viruses and try to use a virus firewall.
(4) Before turning on the host, turn on peripherals such as monitors and printers. Turn off the host first, and then turn off the monitor.
(5) Turn it off after work. If you don't use the computer for a long time, please turn off the main power switch.
(6) If conditions permit, air conditioning must be installed in the computer room, and the relative humidity should be 30% ~ 80%.
(7) It is best not to use the computer host/monitor without power for a long time (such as 1 ~ 3 months).
(8) Don't switch the computer on and off frequently. The time interval between two startup times should be at least 10 second, and preferably not less than 60 seconds.
(9) Don't turn off the power supply when reading or writing the hard disk (it can be judged by whether the red light of the hard disk is on). Wait for about 30 seconds after turning off the computer before moving the computer.
(10) Do not move the computer in use.
(1 1) Pay attention to dust prevention, keep the machine airtight, and keep the use environment clean and hygienic.
(12) Avoid direct glare on the display screen and stay away from strong magnetic fields.
(13) To keep the monitor screen clean, try to use a dry soft cloth when wiping the screen.
(14) Don't let water, food and other liquids get on the keyboard and screen. Press the keys lightly and quickly.
(15) Don't pull the mouse line and keyboard line.
(16) Organize the directory structure of the disk reasonably, and often back up the important data on the hard disk.
Question 7: What professional advice and reminders should I pay attention to when using a laptop? Look, we remind you of these after-sales notebooks. We just hope that you can treat your computer well and treat it as your friend. This is the real "friendship".
Whether the notebook computer can be kept in good condition has a great relationship with the use environment and personal habits. Good use environment and habits can reduce the complexity of maintenance and maximize its performance.
Several environmental factors leading to the damage of notebook computers;
1. Vibration-including falling, hitting, slapping and placing on a surface with large vibration. When the system is running, external vibration will cause damage or even damage to the hard disk, and vibration will also cause damage to the shell and screen.
2. Humidity-The humid environment also does great damage to the notebook computer. Storage and use in humid environment will lead to corrosion of electronic components inside the computer and accelerate oxidation, thus accelerating the damage of the computer.
3. Cleanliness-It is very necessary to use the computer in an environment with as little dust as possible. Serious dust will block the cooling system of the computer, which will easily lead to short circuit between internal parts and reduce or even damage the performance of the computer.
4. Temperature C It is also necessary to keep the computer at the recommended temperature. Using the computer at the temperature of supercooling and overheating will accelerate the aging process of internal components, and even cause the system to fail to boot.
5. Electromagnetic interference-strong electromagnetic interference will also cause damage to notebook computers, such as telecom rooms, high-power transmitting stations, power plant rooms, etc.
The best use environment of notebook computer (recommended)
Note: The above parameters are recommended values. Please refer to the specification parameters in the user manual to define the content options of the detailed operating environment parameters of the notebook computer.
Incorrect handling and storage will also damage your computer in advance.
suggestion
Use a special computer bag when carrying a computer.
After the computer is completely shut down, put it in the computer bag to prevent the computer from overheating and damage. Turning off the LCD screen directly may cause the system to fail to shut down completely.
Do not pile up with other parts, clothes or sundries to avoid squeezing or scratching the computer.
Take it with you when traveling. Please don't check it, lest the computer be smashed or dropped.
When the temperature difference changes greatly (that is, when the indoor and outdoor temperature difference exceeds 10℃, for example, the outdoor temperature is 0℃ and you suddenly enter a room at 25℃), please do not turn on the computer immediately, because the large temperature difference is likely to damage the computer or even make it impossible to turn on the computer.
The battery of a notebook computer is a consumable. Once the battery is opened for use, it will start the aging process. The aging rate varies with the chemical characteristics of the battery. The aging speed is also related to the usual use method. If the battery is frequently charged and discharged, it will accelerate the aging of the battery. After the battery is used for more than a period of time, the power supply time will be gradually shortened until it cannot be used. Therefore, it is normal that the battery life is shortened. Although you usually use an external power supply, it seems that you don't need a battery. In fact, the aging process of the battery has been going on with the passage of time. Using less batteries can only delay this process, but not stop it.
Factors affecting battery life include
Battery charging/discharging time
Ambient temperature (it is recommended to use the computer below 30℃)
Battery storage temperature
The amplitude of vibration suffered by the battery.
Several "principles" of battery use
1. In AC adapter mode, if the battery is not charged/discharged during use, its service life will be longer than that of ordinary batteries.
2. Less charge and discharge times can prolong the service life of the battery to a certain extent.
3. When the indoor temperature reaches above 35℃, the loss rate of the battery will be much faster than that at room temperature.
4. Dropping and bumping the battery will also accelerate the battery loss.
The following applications will obviously shorten the working time of the battery.
1. Use optical disk drives, such as DVD, CDROM and CDRW drives.
2. Use wireless communication devices, external PC cards or USB devices.
3. Use high-brightness screen display settings, 3D screen savers or other large programs, such as 3D games.
4. Run the computer in the highest performance mode, that is, set the power management scheme to "always on" or "maximum battery mode".
5. Active programs, including programs running in the background.
6.LCD brightness (the brighter the LCD ... >>
Question 8: Proper use and precautions of notebook computers Notebooks are sophisticated equipment, so you need to use them carefully and correctly. Although the design and test of notebook computer ensure its durability and reliable function in ordinary environment, you still need to master some correct usage and precautions.
It is forbidden to squeeze
Everyone is very careful to avoid the "laptop" being hit and falling from a height. It is very difficult to put heavy objects on the "laptop". One thing to remind is that when the computer is put in the bag, the zipper of the bag must be zipped up, or the computer must be taken out after the zipper is unzipped. One of my laptops didn't come out in time because the zipper was open. I forgot to open the zipper when I took the computer after handling other things. As a result, the computer fell to the ground after carrying the bag. This is the experience I gained with a painful lesson.
In addition, don't use boxes or handbags that are too small or too tight to hold laptops. Internal pressure may damage the laptop. Using high-quality computer bags will provide security protection for notebook computers.
Guan ai LCD screen
Usually, everyone pays great attention to avoid scratching, bending, bumping or dragging the LCD screen of a "laptop". I also want to remind you not to put anything between the LCD screen and the keyboard or under the keyboard, and when moving the laptop, don't just hold the LCD screen, please hold the area under the keyboard.
Telephone lines are not answered casually.
Do not connect PBX or other digital telephone lines. Your laptop is only used for PSTN telephone network. If you use another telephone line, you may damage the modem. If you are not sure about the type of phone line you are using, please contact your phone line service provider. Many hotels or office areas use digital telephone lines, so please confirm before connecting the telephone lines in these places.
Soft plugging and unplugging should be gentle
When installing hard disk, floppy disk and CD-ROM drive, do not touch the central part of CD-ROM drive or floppy disk drive. When holding the disc, don't touch the surface of the disc, just hold the edge of the disc. When removing devices such as optical drive, hard disk or floppy disk from notebook computer, don't squeeze, break or hit these devices. Moreover, when inserting the floppy disk, don't tilt the floppy disk, otherwise it may damage the floppy disk.
When you are not using external or pluggable hard disks, floppy drives or optical drives, please put these devices in appropriate packaging. When installing an optical drive or floppy drive in the Ultrabay slot, it is recommended that you unplug the power adapter.
Don't put multiple labels on the floppy disk, or too many labels may fall off or stick and block the floppy disk.
Install the software carefully
Notebooks are mainly used for mobile office. You should only install the software that you are familiar with and have no problems. Don't try some software that you are not sure about. Don't install too much software on your laptop. If the system is too complicated, it will inevitably cause some conflicts or problems and hidden dangers. In addition, notebook computers should be more alert to viruses, because you are likely to meet some people or occasions, and you should use your computer to look at floppy disks or CDs.
Save driver
The hardware drivers of notebook computers have some very targeted drivers, so you must make a good backup and pay attention to preservation. If it is a public microcomputer, you should pay more attention to the handover, but it is more troublesome to find a driver after the laptop is lost.
The placement environment is very special.
Although ThinkPad climbed Mount Qomolangma with China's national mountaineering team and traveled all over the country with the famous car traveler Ms. Liao Jia, it should be remembered that they never put their laptops in vehicles or places where there might be severe bumps. And generally speaking, don't put the laptop at a place higher than 35℃ or lower than 5℃, and don't put it in the range of electronic equipment with strong magnetic field 13cm, including motors, magnets, televisions, refrigerators or large audio equipment. Don't put your laptop under a window with direct sunlight for a long time, because direct sunlight can easily accelerate the aging of the shell.
Regular cleaning
Clean the laptop regularly. Regarding external cleaning, it has been mentioned before; On the one hand, internal cleaning should stick to the work of killing viruses; on the other hand, it is necessary to frequently visit websites related to "notebooks" and accumulate notebook experience as much as possible, which is also very helpful for you to use your notebook computer better. ...& gt& gt
Question 9: Precautions for using notebook computers:
Use less optical drives.
CD-ROM drive is the oldest part in computer at present, and most notebook CD-ROM drives are no exception. Most of the optical drives of notebook computers are special products. It is troublesome to replace them after being damaged, so we should cherish them. Watching VCD or listening to music on a laptop is not a good habit. You can buy an advanced VCD player or CD walkman with enough money to replace the optical drive of your laptop. Why do you want to watch CDs on your laptop? In addition, the pictures and sound effects on the laptop are probably mediocre.
Install the software carefully
Notebooks are mainly used for mobile office. You should only install the software that you are familiar with and have no problems. Don't try some software that you are not sure about. Don't install too much software on your laptop. If the system is too complicated, it will inevitably cause some conflicts or problems and hidden dangers. In addition, notebook computers should be more alert to viruses, because you are likely to meet some people or occasions, and you should use your computer to look at floppy disks or CDs.
Save driver
The hardware drivers of notebook computers have some very targeted drivers, so you must make a good backup and pay attention to preservation. If it is a public microcomputer, you should pay more attention to the handover, but it is more troublesome to find a driver after the laptop is lost.
Pay attention to the use environment
There are circuits and components on the notebook computer, so be careful not to use it where the magnetic field is too strong. Of course, you can't use it when flying. The stewardess will remind you. Don't leave your laptop under a window with direct sunlight for a long time. If the sun is always in direct sunlight, it is easy to accelerate the aging of the shell.
Heat dissipation problem
Heat dissipation may be one of the difficult problems in notebook computer design. Due to the limitation of space and energy, you can't install a big fan like a desktop in your laptop. I took apart one of my Pentium-class laptops, and saw that there was only a piece of metal on the CPU, and the remaining heat was probably radiated from the chassis bottom plate. Therefore, when using, pay attention to maintaining good ventilation conditions for the heat dissipation parts of your machine, and don't block the heat dissipation holes. If the machine dissipates heat through the bottom plate, do not leave the machine on a hot poor conductor for a long time.
Avoid falling
The first commandment of a notebook is to fall. Notebooks are usually packed in portable bags, so be sure to put the bags in a safe place when placing them. When you put it in your bag, be sure to zip it up, or unzip it before taking out your notebook. One of the author's notebooks was not taken out in time because the zipper was open. I forgot to unzip my notebook when I finished other things. As a result, the computer fell to the ground after carrying the bag. This is an experience with painful lessons. In addition, because laptops are always with you, it is inevitable that they will bump into each other. Laptops really can't stand bumps, so be extra careful.
Prohibition of demolition
If it is a desktop, even if you don't know the computer, it may not have serious consequences, but a notebook computer is different, and unscrewing a screw may bring trouble. I have used my laptop for many years, but I dare not take it apart completely. Not only may it be damaged carelessly, but also the manufacturer may not accept the warranty for the computer that he has dismantled. So, if you have hardware problems, you'd better go to the manufacturer to deal with them.
I want to add some experience here. You must buy a laptop from a famous brand manufacturer. Because all kinds of accessories of notebook computers are not universal, many of them are not easy to buy in the accessories market. After three or two years, if they are not famous brand manufacturers and can't even find an agent, how can they talk about service?
Question 10: What are the precautions for long-term use of computers? Eight Harms of Long-term Use of Computers and Their Prevention Methods
[Gu Tao Bar]
Item 1: Electromagnetic radiation
Symptoms: insomnia, endocrine disorders.
Cause of disease: the monitor is too hot, and there will be a considerable amount of electromagnetic radiation when working, which will ionize the air, constantly produce positive charges (positive ions), and constantly neutralize the negative ions in the air, resulting in almost zero negative ion content. The more beneficial negative ions, the more harmful positive ions. Being in an environment with too many positive ions for a long time, it enters the lungs through breathing, and then it is transported to various tissues of the human body with blood circulation, which makes people's blood and body fluids acidic, delays the normal metabolic function of the body and accumulates toxins in the body. Causes insomnia, decreased immunity, and female endocrine disorders.
Mitigation method
1. Clean the office environment carefully. Because positive ions will be firmly adsorbed on dust particles, the more dust, the more positive ions.
2. Drink more tea. Tea polyphenols and other active substances contained in tea help to absorb radioactive substances.
3. Most of the radiation emitted by the display does not come from its front, but from its sides and back. So, don't point the back of the monitor at the back of your colleague's head or the side of your body.
4. Drink green tea often. Green tea is the most talked about health drink in recent years, because it contains powerful antioxidants catechol and vitamin C, which can not only eliminate free radicals in the body, but also make the accessory renal cortex secrete hormones against stress, greatly improving the mood. But it is best to drink it during the day, so as not to affect sleep.
5. Mung beans can clear away heat and detoxify, induce diuresis and reduce swelling, and coix seed can strengthen the spleen and stop diarrhea, and lighten the body and replenish qi. Often need to work late or when fidgety, dry mouth, constipation, it is very helpful to eliminate fidgety.
6. Washing your face often can prevent radiation waves from harming your skin.
7. Put a pot of plants or water under the computer desk to absorb the electromagnetic waves emitted by the computer.
8. Try to use LCD monitors.
9. Wear a radiation-proof Chinese-style chest covering.
Item 2: Dust field
Symptoms: skin allergy
Cause: An electrostatic field will be formed around the monitor when it is turned on, which will almost suck the dust suspended in the air of the whole room into its own field, causing facial skin to be subjected to * * *, resulting in allergic skin rash. Sitting in front of the computer, your surroundings are full of air containing a lot of dust particles, so the user's skin is very prone to allergic phenomena such as rash.
Mitigation method
1. Don't put mountains of papers and documents around the computer, but put all the necessary documents in the cupboard in different categories, because the dust on papers and documents is usually not easy to clean up.
2. Wipe the surface of the computer desk with a wet cloth dipped in antistatic agent.
3. Always open the window for ventilation.
4. Rub some moisturizing cream on your face before using the computer, or soak the towel with chamomile extract (a simpler method is to use a wet chamomile tea bag) and apply it directly to your forehead and cheeks.
5. Put a cactus on the computer desk, because the acupuncture of cactus can absorb dust.
6. Clean the keyboard frequently. Wash your hands when and after using the keyboard and before eating. Cover the keyboard with a cloth when not in use. Because the keyboard is uneven, it is very easy to accumulate dust, which will be hidden by dermatoses and cold germs ... >>
