The temperature of playing games on laptops will be very high. How to maintain the computer?

Basic knowledge of computer maintenance Speaking of daily maintenance of computers, you can't relax at all. The influence of environment on computer life can not be ignored. The ideal working temperature of the computer is 10℃-30℃. Too high or too low will affect the life of computer accessories. Its relative humidity is 30%-80%, too high will affect the performance of CPU, graphics card and other accessories, and even cause some accessories to short circuit; Too low is easy to generate static electricity, which is not conducive to the use of accessories. In addition, the dust content in the air has a great influence on computers. If there is too much dust, it will corrode the circuit boards of various accessories and chips for a long time; If the content is too small, electrostatic reaction will occur. Therefore, it is best to keep the computer room clean and tidy. Some people think that using computers less or for a short time can prolong the life of computers, which is a one-sided and vague view; On the contrary, if the computer is not used for a long time, the computer accessories will be damaged due to moisture, dust, sweat stains and other reasons. Of course, if the weather is humid to a certain extent, such as: there is moisture on the surface of the monitor or chassis, don't start the machine without drying at this time, so as to avoid unnecessary losses such as short circuit. Good personal habits also have a great influence on computers. Therefore, please perform the startup and shutdown procedures correctly. The boot sequence is as follows: peripheral devices (such as printers, scanners, UPS power supplies, modems, etc. ) should be turned on first, and then the monitor power supply is not connected to the host; The shutdown sequence is reversed: turn off the host first, and then turn off the peripherals. The reason is to minimize the damage to the host. Because when the host is powered on, it will produce a strong impact current to the host at the moment when the peripheral is turned off. After a period of time, you can't switch it frequently, because it will have a great impact on all accessories, especially on the hard disk. Generally, the time between shutdown and next startup should be at least 10 second. Pay special attention to avoid turning off the computer while it is working. For example, when the computer suddenly shuts down when reading and writing data, it is likely to damage the drive (hard disk, floppy disk, etc.). ); You can't move the machine when it is working normally. When shutting down, you should pay attention to exit the Windows operating system, close all programs, and then exit in the normal shutdown order, otherwise the application may be damaged. Of course, even when the machine is not working, try to avoid moving the computer, because excessive vibration will damage the hard disk, motherboard and other accessories. Home computer maintenance method 1, the computer should be placed in a place where it will not shake and the table is smooth and stable; When placed on the floor, a stable board should be placed at the bottom of the main engine. 2. If the power supply at the computer is unstable or power is often cut off, it is best to add a voltage regulator with grounding function or UPS power supply. 3. The power cord, mouse cord, keyboard cord, speaker and printer cord on the computer should be arranged behind the computer as far as possible, keeping a certain distance from the wall to avoid knotting. 4. Buy a computer desk with a sliding keyboard bracket, or add a retractable keyboard bracket on the old desk to protect the keyboard and increase the use space of the desktop. 5. Don't drink water, smoke or eat snacks in front of the computer, so as to avoid the above foreign objects infiltrating into the keyboard and other equipment, causing unnecessary damage. 6. When the computer is in use, you should first turn on the power supply of peripheral equipment, such as display printer, and then turn on the power supply of the host. When the computer is not in use, the shutdown sequence is reversed. 7. When using the computer, don't plug and unplug peripheral devices casually to avoid damaging external devices and ports. 8. When using a computer, it is best to choose a chair with adjustable backrest height and armrest. Short people should also find a footstool to put their feet on. 9. Please keep the cooling holes of computer equipment clean, and don't put paper or other sundries on the computer or monitor, otherwise it will easily cause poor air circulation, make it difficult for the computer to dissipate heat and shorten the life of the computer. 10, you'd better wash your hands before operating the computer to avoid soiling the keyboard. Don't use the computer in dusty places. Cover the computer with a dust cover after use to prevent dust from entering the machine. 1 1. If the keyboard is found to be dirty, clean it with an alcohol cotton ball. The ball at the bottom of the mouse should also be cleaned with alcohol frequently. 12, try to keep the monitor screen perpendicular to the window to avoid glare that may be reflected; Or add a reliable protective screen and a light dedicated to reading documents. Don't put the computer in direct sunlight. 13. When using the mouse, avoid using it on an uneven and unclean desktop. It is best to add a clean mouse pad on it. 14. Storage media such as disks and CDs should always be kept clean, and it is best to put them in special disk boxes. Storage media with important data backed up should be placed separately from the computer to avoid some accidents and damage at the same time. 15, you should use genuine software as much as possible, use less executable files with unknown functions, and don't use external disks that are not absolutely safe to avoid virus invasion. Install virus firewall software to prevent virus invasion and upgrade antivirus software regularly. 16, it is best to check every time an accident occurs (such as collision, sudden power failure, etc.). ) and at regular intervals (such as once a week and once a month) by using disk check commands (such as CHKDSK, ScanDisk); Frequently execute disk defragmentation commands (such as defragmentation) to improve machine performance. Users with WIN95 or above can only use the disk defragmentation command in windows, otherwise it will lead to some unexpected errors. 17. If non-family members often come in and out of the house, or guests will come soon, it is best to add passwords or other security measures to computers or some important software and files to prevent others from destroying, peeking and stealing; When outsiders use computers, it is best to watch them in person to avoid losses caused by misoperation or other reasons. 18, a set of maintenance tools should be prepared, including a can of compressed air, a can of alcohol used to wipe the mouse or CD-ROM drive, and a wiping cloth that will not generate static electricity. How to maintain the dust on the laptop display screen can be brushed off with a dry soft brush, and no more cleaning means are needed. But if the screen is covered with fingerprints, saliva and other unknown stains, you need some special cleaning methods. It is recommended to use the LCD cleaner made by Sony. If you can't buy this cleaner, you can also use high-grade glasses cloth with a little water to clean it. In the protection of laptop screen, the most taboo is pressing, pushing, scraping and incorrect screen opening. The LCD screen of notebook computer is composed of multilayer reflector, filter and protective film, and any one of them will make the display of the screen defective. Although most notebook computers will pass the tests of top cover compression resistance and screen opening and closing times in design and delivery, the screen of notebook computers may be damaged early due to improper use and transportation methods. During the transportation and carrying of notebook computers, care should be taken not to press the screen and the top cover, which may lead to the cable breakage of the screen and the top cover breakage, which is also the most common screen damage. Brand-new machines are usually wrapped in a layer of cotton paper, which can be placed between the screen and keyboard of a laptop. If the laptop uses a pointing stick mouse, please remove the pointing stick cap and store it in another place to protect the screen from being scratched. This is especially important for DelI and IBM notebooks with long keyboard strokes. These notebooks are easy to damage the screen after being pressed during transportation. How to maintain a computer How to use and maintain computer hardware: 1. Never bump into each other when using the computer. Especially when reading a disk (the red indicator light on the chassis keeps flashing), it mainly happens when the computer is just turned on or the program file is opened. At this time, the hard disk is rotating at a high speed of 7200 times per minute and 120 times per second. At this time, if you encounter strong vibration, the magnetic head may hit the disk surface (because there is only a gap between the reading head and the disk surface of the hard disk). At such a high speed, even a slight touch may cause fatal scratches on the hard disk in your computer, leading to the scrapping of the hard disk, and the personal data and files stored in the hard disk that you have painstakingly collected for many years may be lost, causing irreparable losses. 2. Don't turn it on immediately in rainy days. In case of foggy weather or rainy and humid weather in April and May in Chu Qing or the south, especially when you wake up and find that the ground is wet, water drops appear on the wall or even flow downwards, you should immediately realize that your room is very wet and water drops may appear on the circuit board of computer parts. If you start it hastily, it may cause a short circuit and burn out computer parts. When the monitor is turned on in wet weather, the monitor often flashes and flashes horribly, which is caused by the humidity in the monitor. At this time, it is necessary to turn off the monitor immediately and use a hot air blower to blow hot air to the small air hole above the monitor. When the chassis is wet, you can blow hot air to the air hole behind the chassis, or open the chassis to blow hot air to the circuit board inside. After a few minutes, the moisture is removed, the computer is turned on, and everything will be fine. (Note: The more upscale the room decoration, the wetter it may be, and the more unsafe it will be, because at present, the wall paint and paint are airtight, and the wooden boards coated on the wall are not only wetter, but also may cause fire and disaster). It is hot in summer, and it is easy to burn the internal parts of the machine if it is turned on continuously for too long, which will accelerate the aging of the parts and shorten the service life. Even if your chassis is equipped with the maximum power fan and cooling system, your monitor can't stand it. 1 and 2 hours, it is best to turn off the computer, let the computer cool down and monitor for a while. If it is necessary to turn on the computer for a long time, it is best to find a strong electric fan and blow it continuously in the direction of the back of the computer case and the top of the back of the monitor, which can greatly reduce the temperature in the case and the monitor and avoid overheating, burning or aging too fast. 4. Shut down in time in lightning weather and cut off the main power supply. Summer is the season with the most thunderstorms. If it thunders, remember to turn off your cell phone in time, especially when the thunder is loud, which means that Thundurus is moving above your house. At this time, a lightning may be enough to destroy many household appliances. The instantaneous strong current of lightning will break into your home through outdoor wires and burn fragile appliances. (The author in a thunderstorm last summer, a lightning destroyed an Adsl cat and a Hub. Although the computer was turned off long ago, a keyboard was destroyed for no reason. In addition, the electronic clock hanging on the wall went crazy in an instant, and the numbers jumped wildly, showing the power of lightning! 5. Turn off the main power supply of the socket after going out or turning it off at night, including the power supply of Adsl and Hub. Because the existing cabinets are all smart cabinets, automatic shutdown does not completely turn off the power supply. Some computers are also equipped with automatic power-on function for incoming calls. After going out or falling asleep, if there is a sudden power outage or a call, the computer will automatically turn on. If the power supply is not really cut off at the same time after a large-scale power outage in the city, the instantaneous surge current will be quite large. If the power is not really cut off, computers or Adsl cats and hubs will be burned. At the same time, it can also prevent lightning accidents after going out. 6. Don't plug and unplug computer parts, including USB flash drives. Never plug or unplug computer parts with electricity, even parts that can be hot-plugged, such as mice, because most computers have no grounding wire, and some computer shells have serious leakage. When hot-plugging, they accidentally bumped into the metal protrusion of the shell, which caused the keyboard and mouse interface or the interface with the motherboard to be short-circuited and burned, which would cause great losses. A friend's USB flash drive was unplugged because it didn't quit normally. Never unplug the USB flash drive when the indicator light flashes (reading and writing data), but unplug it after the indicator light goes out. If the USB flash drive can't exit normally, it means that the files or programs inside are being opened or monitored by antivirus software. You can try turning off the antivirus software. If it doesn't work, turn off the computer normally and pull out the USB flash drive, and you'll be fine. Note: After double-clicking the small icon "Safely Remove Hardware" in the lower right corner and selecting Stop, Windows-me prompts "Now it is safe to remove this device from the system", but the indicator light is still on, indicating that the prompt is false. To open "My Computer", windows-me right-clicks the mouse on the drive letter of the U disk, selects "Eject" to turn off the indicator light, and then pulls it out. The usage of different USB flash drives is different. As long as you make sure that the USB flash drive is not opened or the files in the disk are not used, there will be no big problem. 7. Be careful to prevent static electricity, and don't touch the circuit board and electronic components with your hands. Some people often unplug the memory stick from the motherboard or the hard disk from the computer because of the crash or some special needs, and never pay attention to the harm of static electricity. They use their fingers (golden fingers) to touch the contacts of the motherboard or memory stick, or pinch the circuit board on the back of the hard disk (some integrated circuit boards of the hard disk are exposed). Fortunately, you don't have much static electricity, or your skin is wet and there is no static electricity in summer. If you change to a dry winter and wear a sweater made of all nylon chemicals, the result may be completely different. The static electricity at this time is enough to make you feel scared. Everyone has the feeling of being' shocked' by his partner wearing a nylon sweater, and should know the power of static electricity. Static electricity may even cause fire. Before touching electronic components to release static electricity, it is best to touch aluminum alloy doors and windows or slightly larger metal products by hand. 8. Setting the power-on password helps to protect the computer. Setting the power-on password is beneficial to protect the computer. For example, monitors are often plugged in loosely or loosely. After booting, the display screen is black, but the hard disk indicator keeps flashing, indicating that the system still enters Windows. If you can't operate the keyboard blindly, you have to turn off the power. Setting passwords is also very useful for repairing computers. Sometimes the computer is restarted just to check the motherboard, graphics card model, hard disk and memory size or CD-ROM drive status. If you can't see clearly, you have to close it several times. If you set the power-on password, you can see it clearly without entering Windows. If the computer doesn't display or often crashes, and it has been found that the graphics card or memory is in poor contact or the hard disk cable or CPU is in poor contact (especially when the old slot is plugged into the CPU), you can unplug the components yourself and wipe them with alcohol and brush to dry them, but you can't be sure whether they are in good contact. At this point, if you set the power-on password, you can know whether the graphics card, memory or CPU are plugged in after a short pause, and you can also know whether the hard disk cable is plugged in, because in this way, you can effectively avoid crashing when entering Windows and then forcibly shutting down, effectively preventing frequent switching on and off to damage the hard disk. (Note: the power-on password refers to the password to be entered as soon as the computer is turned on. Don't mistake it for the password when entering Windows) < BR<p>.
