Complete Computer Maintenance Tips
After the computer has been used for a period of time, the running speed of the program becomes slower and slower. From time to time, blue screens, crashes, etc. may appear, and the noise when the computer is running also increases. It’s getting bigger and bigger... My beloved computer no longer has the original color. What’s going on? This is mainly because you have not performed computer maintenance. Computers also require regular computer maintenance to ensure their normal operation. If you don't know how to do computer maintenance, let's do it together.
Computer maintenance - cleaning hardware
After a computer is used for a long time, dust and other dirt will accumulate inside and outside the fuselage. These factors will harm the computer. Therefore, it is very necessary to clean the computer at ordinary times or for a period of time.
1. Cleaning Tools Computer maintenance does not require very complicated tools. For general dust removal maintenance, you only need to prepare a Phillips screwdriver, a flat screwdriver, and a paint brush (or oil brush, ordinary brushes are easy to remove hair and should not be used). . If you want to clean the inside of a floppy drive or optical drive, you also need to prepare lens wipes, a hair dryer, anhydrous alcohol, absorbent cotton balls, a clock screwdriver, tweezers, a paper clip, clock oil (or sewing machine oil), and butter.
2. Precautions 1. Before opening the case, confirm the warranty period of each computer accessory.
Note: For brand-name machines within the warranty period, it is recommended not to open the case and clean it yourself, because this means that the warranty rights are lost. For brand-name machines within the warranty period, you can take them to a repair center and ask professionals to perform internal dust removal.
2. Be careful when handling, because all parts of the computer are precision instruments. If you accidentally drop it to the ground, you will die.
3. When disassembling, pay attention to the orientation of each plug-in cable, such as hard disk cable, floppy drive cable, power cable, etc., for correct restoration.
4. When fixing each component with screws, you should first align the position of the components and then tighten the screws. Especially for the motherboard, a slight position deviation may lead to poor contact of the plug-in card; uneven installation of the motherboard may cause poor contact of the memory module and adapter card or even cause a short circuit. Over time, it may even deform and cause malfunction.
5. Since the integrated circuit devices on computer boards are mostly manufactured using MOS technology, this type of semiconductor device is quite sensitive to electrostatic high voltage. When people or objects with static electricity touch these devices, electrostatic discharge will occur, and the released electrostatic high voltage will damage these devices. Pay special attention to electrostatic protection when maintaining your computer.
After preparing the tools and understanding the precautions during operation, you can start cleaning the computer.
3. Cleaning of external equipment
1. Cleaning of the monitor. Monitor cleaning is divided into two parts: the casing and the display.
Step 1 The main reason why the outer shell turns black and yellow is dust and indoor smoke pollution. Special cleaning agents can be used to restore the shell to its original appearance.
Step 2 Use a soft brush to clean the dust in the gaps of the heat dissipation holes. Sweep gently along the direction of the gap, and use a blower bag to blow off the dust.
Step 3. Cleaning the display screen is a little troublesome. Since the display screen now has a protective coating, you cannot use any solvent-based cleaners when cleaning. You can use glasses cloth or lens tissue to wipe it. . The wiping direction should be in one direction, and the wiping cloth surface should be replaced multiple times to prevent the cloth surface that has occupied dirt from scratching the coating again.
2. Clean the keyboard and mouse.
Step 1. Turn the keyboard upside down and tap the keyboard to remove the debris that caused the keyboard keys to jam.
Step 2 Use a neutral detergent or computer-specific cleaner to remove difficult-to-remove stains on the keyboard, scrub with a damp cloth and dry the keyboard.
Step 3 Use cotton swabs to clean the dirt in the gaps between the keyboard.
Similarly, after using the mouse for a long time, it will not listen to commands. At this time, it needs to be dusted. Generally speaking, a mechanical mouse only needs to clean the rolling ball and rolling axis in the "body".
Step 1 Unscrew the screw at the bottom of the mouse and open the mouse.
Step 2: Use detergent to clean the dirt on the mouse rolling ball and scroll shaft, and then install the mouse.
Due to the sealed design often used in optical mice, dust and dirt will not enter inside.
When using a mouse, it is best to use a mouse pad, which will prevent dust and dirt from entering the mouse.
3. Cleaning of the chassis shell. Since the case is usually placed under the computer desk, and we don’t pay much attention to cleanliness, dust and dirt can easily adhere to the case shell. You can first use a dry cloth to remove floating dust, then use a cloth dipped in detergent and water to wipe off some stubborn stains, and then use a brush to gently brush off the dust on the surface of various interfaces at the rear of the chassis.
4. Cleaning the inside of the host After completing the cleaning of the external equipment, the most important internal cleaning of the host begins. Since the chassis is not sealed, a lot of dust will accumulate inside the chassis after a period of time, which is very detrimental to the operation of the computer hardware. Excessive dust can easily cause computer malfunctions and even cause serious consequences of burning the hardware, so it is very harmful to the inside of the host. Dust removal is very important and needs to be performed regularly. Generally, dust removal once every three months is appropriate. The above work needs to be completed regularly. When cleaning, simply clean the computer casing.
1. Disassemble the host.
Note: Before disassembly, be sure to turn off the phone, discharge any static electricity from your body or wear anti-static gloves before performing the following operations. Step 1: First unplug all peripheral cables from the back of the chassis, use a screwdriver to unscrew a few screws on the back of the chassis, and remove the chassis cover.
Step 2 Then lay the host down with the motherboard facing downwards. Use a screwdriver to unscrew the screws fixing the card on the upper edge of the strip window. Then pinch the upper edge of the interface card with both hands and pull it out vertically. Remove the interface card.
Step 3: Then pull out the power plugs of the hard disk, optical drive and floppy drive in the horizontal direction. Pull out the data cable in the same way as the power cable. Then use a Phillips screwdriver to unscrew the two sides of the drive bracket and secure it. Remove the drive screws and remove the drive.
Step 4: Unscrew the four screws on the back of the chassis and the power supply, and remove the power supply.
Step 5: Unplug the various wiring plugs plugged into the motherboard. When removing the double-row 20-pin plug of the power supply, pay attention to the small plastic card on the plug. Pinch it and pull straight up to remove the power plug.
Step 6 Use a little force to pull the plastic clips at both ends of the memory slot outward so that the memory module can pop out and remove the memory module.
Step 7: When disassembling the CPU radiator, first press the spring tab at the far end and let the spring tab disengage from the slot of the CPU socket to take out the CPU radiator.
Step 8: Unscrew the screws that secure the motherboard to the chassis, and take the motherboard out of the chassis.
2. Start cleaning. After completing the disassembly, the next step is to dust them and restore them to their original appearance.
Step 1 Clean the motherboard. Use a brush to clean the dust on the surface of the motherboard. Then use an oil paint brush to clean the various slots and drive interface plugs. Then use a hair dryer or hair dryer to blow away the dust.
Tip: If there is oil on the metal pins in the slot, you can use absorbent cotton balls dipped in computer-specific cleaner or absolute ethanol to remove them.
Step 2 Clean the memory module and adapter card. You can first use a brush to gently clean the dust on the surface of various adapter cards and memory modules, and then blow it clean with a blower. Use an eraser to wipe the front and back of the gold fingers of various plug-in cards to remove dust, oil or oxidation layers.
Step 3 Clean the CPU cooling fan. Use a small Phillips screwdriver to unscrew the fixing screws on the fan and remove the cooling fan. Use a small brush to gently wipe the blades and edges of the fan, and then use a blower to blow away the dust. Then use a brush or damp cloth to wipe away any accumulated dust on the heat sink.
Tip: Some cooling fans are integrated with the CPU. There is no way to separate the fan and the heat sink. You can only use a brush to remove dust from the fan blades and bearings, and then use a leather tiger to remove the remaining dust. Blow the dust clean.
Step 4 Clean the power supply. Use a screwdriver to unscrew the screws on the power supply, remove the power supply casing, remove the circuit board of the power supply part, separate the circuit board and the power supply casing, and then use a leather tiger and a brush to clean it. Finally, unscrew the four screws on the back of the power supply, remove the fan from the power supply casing, and clean it with a brush.
Tip: If the power supply is still within the warranty period, it is recommended to use a small brush to clean the dust on the surface of the power supply and the fan blades. Because there is no power supply that has expired, disassembly will void the warranty.
Step 5 Clean the optical drive.
Unfold the paper clip and insert it into the emergency ejection hole on the front panel of the optical drive, open the optical drive tray with a little force, and gently wipe the area with lens test paper clean. If the disk reading ability of the optical drive decreases, you can disassemble the optical drive, gently wipe it with absorbent cotton or lens paper to remove dust on the lens surface, and finally install the optical drive.
Note: Since there is a film on the surface of the lens, be sure to wipe it with a soft dry cloth when cleaning.
After completing all the cleaning work, the next step is to restore these parts. However, if you want your computer to run as before, in addition to cleaning the computer hardware, system cleaning and maintenance are also necessary.
Computer maintenance--system maintenance
Usually when everyone installs and uninstalls software or browses the Internet, a large number of useless files will be left in the system. Once these junk files accumulate too much, they will not only occupy a large amount of hard disk space, but also degrade system performance and even cause conflicts between useful programs in the system. Therefore, it is very important to clean up the system.
1. Clear system trash Step 1: Empty the Recycle Bin trash. Some people think that after deleting the files, everything will be fine. In fact, these so-called deleted files are saved in the recycle bin first, which still takes up a lot of hard disk space. Right-click the recycle bin icon and click "Empty Recycle Bin"
Step 2 Delete temporary files. Right-click the IE shortcut, select "Properties", and click the "Delete Cookies", "Delete Files" and "Delete History" buttons in the "General" tab to clear the temporary files left behind by surfing the Internet. Tip: After clicking the "Delete Files" button, be sure to check "Delete all offline content" in the pop-up dialog box), so as to ensure that the Internet access records can be completely cleared. Step 3 Clear the file name in the Document menu. Click "Start" → "Settings" → "Taskbar and Start Menu" to open the "Taskbar Properties" dialog box. Select the "Start Menu Programs" tab in the dialog box, and then click the "Clear" button. Step 4 Clear the program name in the "Run" list. Run the "Regedit" command, open the Registry Editor, and find "HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/RunMRU". The information in the "Run" drop-down list is displayed on the right side of the registry. To delete an item, right-click the name with the mouse and select "Delete". Be careful not to delete the rows where "Default" and "MRUList" are located.
Step 5 Clear excess fonts and temporary files from the system. Use the font icon program on the control panel to delete unwanted fonts. Delete all files in the Temporary Internet Files folder under the Windows directory to clear temporary files. You can also right-click the "Start" button, then select "Search", enter "*.tmp" in the "Name" dialog box, set the "Search" column drop-down list to the entire hard disk, and then click "Start Search". Finally, delete all tmp files found.
Step 6 Delete unused programs. Use Add/Remove Programs on the Control Panel to clear your hard drive of unused applications.
Note: Never delete the program's file directory directly, because many programs will write information to the Windows system files and registry during installation. Directly deleting program files will not work well. In order to improve performance, it will further clutter the hard disk data.
Tip: There are now some specialized system maintenance software, such as "Windows Optimization Master". This type of software can delete junk files and some records in the system through simple operations, which is very suitable for newcomers. Used by computer friends.
2. Comprehensive optimization of the system. After completing the cleanup of system garbage, a comprehensive optimization of the system can also improve the performance of the system to a certain extent.
1. Use system functions for optimization.
Here we take the most commonly used WinXP as an example to tell you how to use some simple system settings to optimize the system. Step 1 Right-click "My Computer" → "Properties".
Step 2 Select "Hardware" → "Device Manager" in the pop-up window to open the Device Manager window. Expand "IDE ATA/ATAPI Controller", double-click "Main IDE Channel", select "Advanced Settings", select "DMA (if available)" for the transfer mode, and click "OK".
Step 3 Click "Advanced", click "Settings" → "Advanced" → "Change" in "Performance", select "Custom Size", set both "Initial Size" and "Maximum Value" to 2.5 times the physical memory, and then Click "Settings", "OK".
Step 4 Go to "My Computer" → "Properties" → "Advanced", click "Settings" in "Performance", and select "Adjust for best performance" ", click "OK".
Tip: After this setting, the WinXP operation interface will become similar to the Win2000 operation interface, but the speed will be faster than before. This method is suitable for computers Users with low configuration.
Step 5: Check "Turn off System Restore on all drives" in "My Computer" → "Properties" → "System Restore" to save a certain amount of hard disk space. ” and select “Disable System Restore” at the bottom.
2. Use the registry for comprehensive optimization
Click "Start" "Run" and enter "regedti" to open the registry editor.
Step 1 reduces the shutdown steps. Enter the registry editor, open "HKEY_CLASSES_ROOT\Directory\shell", create a new primary key named "Close", double-click "Default" on the right side of the "Close" subkey window, and enter "Turn off computer" in the "Key value" column ". Create a first-level subkey "Command" under "Close", double-click "Default" on the right side of the subkey window, and enter "Rundll32.exe User.exe,exitwindows" in the "Key Value" column. After entering, right-click "Start" and select "Shut Down Computer" to shut down.
Step 2 Accelerate menu display. Open the "HKEY_CURRENT_ USER\ControlPanel\Desktop" sub-item, double-click "MenuShowDelay" in the right window, and enter a value between 0 and 100000 (in milliseconds) in the data box. Generally, set the value between 20 and 400. The smaller the number, the faster the menu will be displayed. It is recommended that users do not set a value that is too low. They will feel uncomfortable when setting this value to "40".
Step 3: Automatically turn off the screensaver before defragmenting the disk. This method is only applicable to Win98. Open "HKEY_CURRENT _USER\Software\Microsoft\Windows\CurrentVersion\Applets", create a new subkey Defrag, and create a new subkey Settings under it, then create a new string value in the right window, name it "DisableScreenSaver", and set it Just set the value to "YES".
Step 4 speeds up the shutdown, only applicable to Win98. Open the "HKEY_LOCAL_ MAC-HINE\SYSTEM\CurrentControlSet\Control\Shutdown" subkey, create a new "String Value" in the right window, name it "FastReboot", and set the "Value Data" to 1. You can feel it after modification The shutdown speed has been significantly accelerated.
3. Display optimization settings
Step 1: Right-click on the desktop, select "Properties" → "Screen Saver", and set the screen saver time to 15 minutes.
Step 2 Right-click on the desktop, select "Properties" → "Screen Saver" "Power", in "Power Plan" set "Turn off monitor" to 30 minutes, and select "Turn off hard disk" Never", because shutting down the hard disk and then restarting it will cause great damage to the magnetic head. Then remove the hook before "Enable Hibernation" in "Hibernation", which can save 100MB of hard disk space and free up some memory.
Step 3 Right-click on the desktop, select "Properties" → "Appearance", and set "Window and Buttons" to "Windows Classic Style" to speed up the menu.
Step 4: Right-click on the desktop, select "Properties" → "Settings" → "Advanced" → "Monitor" and set the refresh rate to above 75Hz so that you will not feel the flickering of the monitor.
Tip: It is recommended not to use additional refresh rates, because this is equivalent to overclocking the monitor, and is more harmful than overclocking the CPU. As long as the monitor refresh rate reaches 85Hz, it is enough. There is no need to deliberately pursue a higher refresh rate, which will greatly reduce the life of the monitor.
4. Hard disk optimization
Step 1 Disk defragmentation. Before defragmenting the disk, be sure to close all other applications and set the virtual memory size to a fixed value.
Step 2 Disk Cleanup. After defragmenting the hard drive, you can use the "Disk Cleanup" program to clean up some redundant files on the hard drive to save some hard drive space.
Of course, if you don’t know much about computers, you can use system optimization software such as "Windwos Optimization Master" and "Super Rabbit Magic Settings" to optimize the system. You just need to run the optimization software and make your selections.
Troubleshooting
After cleaning the computer, sometimes the computer does not behave as expected, and sometimes some minor problems may occur. The following lists some common computer failures to help you troubleshoot these problems in time after encountering them.
1. No response when turning on the computer.
Solution: First make sure your power is on and all the connections are connected in place. Most of the time it is caused by forgetting to plug the power plug into the motherboard. Simply connect the motherboard power plug of the power supply to the motherboard to solve the problem.
2. After booting, it stays on the Windows screen for a long time and cannot enter the system.
Solution: This situation is mostly caused by the hard disk. Check whether the data cable and power cable of the hard disk are connected properly. This will happen if the connection is poor. Re-plug the hard drive's data cable and power cable and make sure they are in good contact to eliminate the problem.
3. After the system starts, the desktop can be displayed, but the icons, menus, toolbars, etc. are not displayed clearly, or the resolution of the monitor cannot be adjusted, and the image is rough.
Solution: It may be caused by the loss of the graphics card driver. You can reinstall the graphics card driver to solve the problem. 4. The monitor does not light up when the computer is turned on, but everything else is normal.
Solution: Gently shake the signal cable between the graphics card and the monitor. If the problem is solved, you need to reconnect the monitor and graphics card. Be sure to tighten the screws on the signal cable.
5. After the network is connected, the Ping command cannot be used to find the other party's computer.
Solution: Generally speaking, either the network cable is blocked or the network card is not working properly. A general network card will have two indicator lights, one is the power light and the other is the data signal light. If the power light does not light up, it means there is a problem with the network card itself or the motherboard card slot, which can be solved after replacement; if the signal transmission light does not light up, it is related to the interface or network cable, which can be solved after checking one by one.
6. Some of the ADSL Modem indicators are not on.
Solution: When the ADSL Modem is connected to the power supply, the power LED indicator will light up. If the LED indicator light goes out, please check whether the power wiring is correct.
7. There is no sound when using the TV card to play TV programs.
Solution: There are two situations. One may be due to a conflict between the sound card and the TV card. Replace the PCI slot of the TV card until the conflict is resolved; the other may be due to a conflict between the sound card and the TV card. The audio inputs between the TV cards are not connected. Find the installation instructions of the TV card, and then use the audio input cable that comes with the TV card to connect the audio output interface of the TV card to the audio input interface of the sound card.
Finally finished, do you think computer maintenance is very troublesome? In fact, as long as you follow the steps mentioned above, there is no problem in restoring your favorite phone to its original appearance. I believe that you are not willing to face a computer that runs very slowly, is full of dirt, and makes loud noises.
If you want your computer to work better for you, it is necessary to do such comprehensive maintenance regularly. According to Hamburger's own experience, such maintenance should generally be done once every three months.
For system maintenance, it is recommended to use Qihoo 360 software, which has comprehensive and practical functions.
The rest depends on your habits. For example, my C drive only installs Microsoft software, such as XP and OFFICE; D mainly contains application software, such as Qianqianjingting, Baofengyingyin, Thunder and the like; E disk games; F disk mainly contains IE temporary files, download files, backups and the like. The poster can set it according to your habits.
How to maintain daily laptop computers
1. LCD screen. The LCD screen should be the most important output device of the entire notebook, and it is also the most delicate component. The general cost will account for about 30% of the entire notebook, so the maintenance of the LCD screen should be prioritized. If you use your laptop for a long time, the brightness of the screen will dim and the screen will turn yellow. This is the aging of the LCD monitor and is a normal phenomenon. The aging speed is what we are concerned about. Generally, this is related to the length of use of the LCD monitor. For notebooks, although they have an advantage in portability, they cannot be turned on for as long as desktops. On the one hand, this is different from notebooks. It is related to heat dissipation and also has a great impact on the life of the LCD monitor. If a current desktop computer is equipped with an LCD monitor, it is recommended not to let it work for a long time. Good laptops, such as Apple and Sony, will have a power-saving mode setting for the LCD display, which means that the screen will automatically dim if the user does not operate it. Generally, this technology is used more often on mobile phone screens. If it is outdoors, it can save power and protect the LCD display. Let’s talk about other habits. Don’t decorate the LCD screen. If the screen is dirty, don’t wipe it off with your hands. It’s best to use high-grade eye cloth or lens wiping paper with a special scrubbing liquid to clean it. Don’t use water, because Water entering the LCD screen can cause a short circuit. As for the protective film, on the one hand it can keep the display screen away from dust, fingerprints and oil stains, but it will also reduce the actual display effect of the LCD. It is up to you whether you want it or not. Another thing to note is not to put heavy objects on the laptop, and be gentle when opening and closing the laptop to avoid damaging the connecting strap.
Second, battery problem. The biggest advantage of a notebook is that it can be carried around, and this feature is undoubtedly closely related to the battery. Without a battery, what you are holding is just a piece of high-tech waste. If your battery lasts less than half an hour, it needs to be charged. , will you feel very depressed? Haha, now let’s talk about battery maintenance. Today's notebooks generally use lithium-ion batteries, while nickel-metal hydride batteries and nickel-chromium batteries are basically no longer used. The difference is that the memory effect of lithium-ion batteries is significantly less than the latter two. Although the memory of lithium-ion batteries is not obvious and can be charged and discharged at will, charging and discharging at will will still affect its life, so unless there are special circumstances, try to avoid charging and discharging at will. For a new laptop, you should pay attention to the following points when charging it for the first few times: try to use the battery power of the laptop to the point where it cannot be turned on, but not until it is completely discharged (that is, completely discharged), and then use it in the shutdown state (do not use it at the same time). Fully charge the battery while charging at the computer. Repeat this several times. In this way, your battery can be said to have exerted its maximum power potential. As long as you do not charge and discharge at will in the future, the memory effect of the lithium-ion battery will not affect the entire battery. The battery has a great impact. If possible, please fully charge and discharge the battery once a month. In addition, let me talk about other precautions. If you use AC external power supply, it is best to unplug the battery, otherwise the battery will be in a hot state for a long time and its lifespan will be affected. Try to use clean electricity (the voltage should not be too high or too low), and be careful not to connect the laptop's power adapter and high-power appliances (such as air conditioners) to the same power strip. The reason is simple. Turning on high-power appliances will cause Instantaneous high voltage. If the battery is not used for a long time, please store it in a cool place (40 degrees seems to be more suitable) to reduce the speed of its internal passivation reaction; please charge and discharge it at least once every two months to ensure its activity. For the unexpected situation of water entering the notebook, the first thing to do is to remove the battery, let the notebook dry naturally, and then send it to a professional after-sales service center for repair.
Three, shell. People rely on clothes, and books should also be beautiful.
As the use time becomes longer and longer, the casing of the notebook will gradually wear out. Especially notebooks such as Sony and Samsung that are designed to focus on aesthetics are more likely to become ugly. On the contrary, the notebooks like IBM will not wear out after a long time. There are big changes. Therefore, we need to prevent appearance wear and tear in advance. Now you can buy special notebook plastic transparent protective molds on the market, which not only loses the appearance, but also can protect the top cover from scratches. In addition to the front, there are also sides. In fact, the sides are more susceptible to wear and tear on the arms and wrists for a long time. If it is summer and is eroded by sweat, no matter how good the material is, it cannot withstand such tossing. I suggest putting some labels on it. , which not only loses appearance but also reduces the wear and tear of the casing. In addition, when using a laptop, it is best to take off metal jewelry such as watches to prevent hard objects from scratching the laptop shell. Haha, it seems that you are too careful. . . . .
Four, hard drive. Whether it is a desktop or a laptop, the hard drive is a very delicate component that is prone to problems. Compared with desktop hard drives, laptop hard drives are more resistant to shocks, but this does not mean that they are indestructible. If you pick it up like a basketball, you should still avoid unnecessary vibrations. Especially when turning on the computer, it is best not to move the notebook.
Five, optical drive. Most laptops are equipped with optical drives as standard. Due to size considerations, laptop optical drives are made very thin, and the discs are usually stuck on the rotating shaft, so try not to use inferior or irregular discs, which are easily damaged. Laser head. If possible, clean the laser head regularly with special CD cleaning tablets. In addition, do not use the notebook optical drive as a CD. On the one hand, the optical drive will generate a lot of heat when working, which is detrimental to the overall heat dissipation. In addition, long-term operation of the optical drive will also have a great impact on the life of the laser head, so do not leave the disc in the optical drive. If you want to use your notebook as a CD, it is also feasible, although it seems a bit wasteful in my opinion. Then you can make your favorite CD into a virtual CD and put it in the hard disk. This can reduce the heat source, and the service life of the hard disk should be longer than that of the optical drive. longer.
Six, mouse and keyboard. There are generally two types of built-in mice in laptops: one is pressure-sensitive and the other is touch-screen. The former has poor strength control and is not easy to operate, while the latter is not easy to operate if your fingers are dry. Solution: Experience the former by yourself, you can’t teach it. Some people are naturally clumsy; as for the latter, there is a solution. Since the touch screen is made of a matte surface similar to PVC material, try not to damage it first. If it is very dirty, you can wipe the surface with a soft cloth frequently. If your fingers are very dry, wash your hands first to minimize the friction between them. Regarding the keyboard, I am afraid that the most common problems are that the keys are worn and the inside of the keyboard is dirty. There is no good solution, otherwise there are only stickers. Pay more attention to cleaning at ordinary times. If it is dirty, you can only clean it. If you don't know how to do it yourself, just take it to the after-sales service center. Another way is to use an external mouse and keyboard. Although it is not convenient to carry, it can still be used at home. After all, it is still more convenient to use a traditional mouse. The "small" keyboard of the notebook is still not as good as the standard large keyboard for typing. Get comfortable.
Seven, other matters needing attention:
1. Heat dissipation problem. One of the difficult problems in notebook design, I should write a special topic if I have the opportunity. Here are some things you should pay attention to: 1. The place where the notebook is placed should have enough space for heat dissipation, and the correct placement method (when the weather is hot, you can prop up the bracket under the notebook to increase the heat dissipation area), and do not block the heat dissipation holes, 2 , do not use the notebook at full load for a long time, the CPU is still a big heat generator, you can give the notebook a rest for 2 hours, 3. Disable some unnecessary devices, such as Bluetooth, optical drives, etc., which can save power. Reduce heat dissipation, 4, and the third point are somewhat repeated. Don’t use the optical drive if you have nothing to do. The optical drive is probably the second largest heat generator. The reasons for this are already mentioned above.
2. Equip your notebook with a beautiful and safe bag. Bell Crystal is recommended. Waterproof, dirt-proof and radiation-proof is still necessary.
3. You should still pay attention to other things you should pay attention to, such as handling it with care and not opening the notebook without permission.
As for software maintenance, I think we can learn from desktop software maintenance
