What should you pay attention to when using a computer?

Correctly turn on the computer before turning on the monitor and then the host. The opposite is true when shutting down; never force it to shut down. ~mP

■Place the computer correctly and handle it with care, away from high temperature, moisture, dust, and direct sunlight. G*%L&]]<

■Be careful about lightning protection in summer. Do not use the computer during thunder and rain. It is best to unplug the power cord. UK6>

■To avoid the influence of magnetic fields on computers, do not place them too close to TVs, speakers, power amplifiers and telephones. Keep them at least two meters apart. 'gPaV]o

■ To prevent cross-fertilization, equip the computer with a dedicated anti-static wiring board. *c9~d$K

■Avoid humid environments. During the rainy season, turn on the computer that has not been used for a long time and run it for a period of time; when the weather is dry, increase the room air humidity appropriately.

Also

1. High temperature

The ideal working temperature of the computer is 10-35 degrees. It is not good if the temperature is too high or too low. High temperature damage mainly affects temperature-sensitive components, such as CPUs. The working temperature of the CPU must not exceed 80 degrees, otherwise it will be very easy to burn the CPU, and it is best to install temperature measurement and alarm software. When using computers in the summer, pay attention to indoor ventilation and cooling, so it is best to have air conditioning in the room with the computer.

2. Moisture

Moisture is also more harmful to computers. Generally, the relative humidity is between 30% and 80%. Improper humidity can easily cause a short circuit. Therefore, when the air is too humid, you must be careful when turning on the machine. Also, be sure not to use the computer with wet hands. Conversely, being too dry is not good either. Too dry can easily generate static electricity, which can also be harmful to computers.

3. Power supply

Unstable power supply is actually a relatively big hazard during the use of computers. Unstable voltage or instantaneous high current can easily cause serious harm to the computer. The normal requirements for computers for alternating current are 220V, 50HZ. It is best to have a good grounding system, and it is best to use a UPS.

4. Dust

Since the computer case is not completely enclosed, and static electricity will attract dust, dust can easily enter the computer. When dust adheres to the surface of the integrated circuit, it will cause poor heat dissipation and, in severe cases, cause a short circuit. Optical drives, floppy drives, and monitors are most afraid of optical drives. If too much dust is absorbed on the optical head of the optical drive, it is easy to cause a sharp decline in the disk reading ability. The damage caused by dust to floppy drives is similar to that of optical drives. In monitors, too much dust can easily cause the monitor to burn out. For example, keyboards, mice and other accessories are afraid of dust. Therefore, it is best to pay attention to dusting the computer

5. Vibration and impact

Hard drives, optical drives, and floppy drives are very afraid of impacts. They all use optical heads to read rotating discs. . If it is hit hard, the disc may be scratched, or the drive may be completely destroyed. No computer user would want this to happen.

6. Static electricity

Static electricity has always been the killer of precision circuit boards. When static electricity accumulates to a certain extent, high-voltage discharge will occur locally, which can easily burn the circuit board. The simple method of protection is to discharge the computer frequently and touch the machine with metal objects.

7. Radio

This killer is often ignored. In fact, it is very harmful to the monitor and can also interfere with the motherboard. When the external radio signal is strong, the electromagnetic field of the display will be severely interfered. If the number of times is too high, the normal working status of the display will be affected. Therefore, it is best to avoid radio interference when using your computer.

1. Power on and off: Computer equipment must be powered off correctly, otherwise its working life will be affected and it is also the culprit of some failures. The correct sequence of turning on and off a computer is: to turn on the computer, first turn on and turn on the power of the computer's peripheral devices (such as monitors, printers, etc.), and then turn on the power of the computer host; the order of shutting down is exactly the opposite, first turn off the power of the host, and then disconnect other devices. Power supply for peripheral devices.

2. Safety instructions for using computer equipment

(1) Computer equipment should not be placed in dusty places (such as windows near the roadside, etc.). There is really no condition to change the location. , it should be covered with a dust cover when not in use; it should not be placed in a humid place (such as where water bottles are concentrated, next to water dispensers, etc., people pouring water can easily splash water on the equipment), and Just pay attention to the heat dissipation of the main chassis and avoid direct sunlight shining on the computer;

(2) It is strictly prohibited to use other electrical appliances, hand warmers and other personal electrical equipment on the dedicated power socket of the computer. Computer equipment should be checked after work Whether to shut down everything before leaving;

(3) Do not move the computer while the computer is working;

(4) Do not plug or unplug devices while the computer is working, frequently Switching the machine on and off, plugging and unplugging various interfaces (except the USB interface) while the power is on can easily burn the interface card or cause damage to the integrated block;

(5) Anti-static, anti-dust, do not allow water to enter the keyboard, mouse and other equipment ;

(6) Back up data regularly and defragment disks. Some data can easily be lost due to frequent hard disk use, viruses, misoperation, etc. Therefore, it is necessary to back up some important data frequently to prevent all the work completed in several months from being lost due to untimely backup. Regularly defragment the disk and clean up junk files in a timely manner to prevent junk files from occupying too much disk space and causing inconvenience to the search and management of normal files. Not only is it easy to delete important files, but also you will not be able to find the files you need when you need them urgently. and other problems;

(7) If problems are found, report them for repair in time so that the machine can always work in a good condition. This includes: whether there are any abnormal problems with the equipment and whether the wiring is loose, etc.;

(Eight) ) To prevent computer viruses, install anti-virus software, update it regularly and check for viruses.

A few points to note when using computers:

1. Automatically link to some unfamiliar websites. When surfing the Internet, be careful not to click on things you don’t understand, especially some pictures or advertisements floating in the browser page. If it affects your browsing of the web, drag the slider up and down until the optimal to the angle of view. In addition, try not to install some Internet plug-ins. Also, do not install Internet Assistant and its toolbar. Such software sometimes affects the normal use of the browser.

2. Do not download and install some small software or programs on the Internet.

3. E-mails from strangers. Receive e-mails from strangers, especially those with tempting titles, such as a joke, or a love letter, and attachments.

4. Check for viruses before using the USB flash drive, and regularly use anti-virus software to check whether there are viruses in the system.
