What can we do to save you? Watch out for five fault-prone areas of laptops

Because of its large function, small size, and light weight, the notebook is more and more favored by consumers. However, because of its small size and high integration, the notebook production technology is much more complicated than ordinary desktops, at the same time, there are many faults, and they are not as easy to solve as the desktop. However, among the many faults, most of them are not caused by the quality of the machine itself, but by improper user operations during use. Which parts of the notebook are more "fragile" during use? Why are they "fragile "? Are we helpless to be "fragile? This article will give you answers one by one.

One of the fault centers: Optical Drive

[Advertisement blocked] The drive failure of the notebook is mainly caused by an error message or an unconfirmed disk when reading the disk, or a very long disk reading time and data cannot be read.

The structure of the laptop optical drive is much more precise than that of the desktop optical drive, and the laser head and other components are loaded on the tray and directly exposed to the outside with the optical drive in and out, so it is more sensitive to dust and stains, there are many non-read disk phenomena that often occur in the optical drive of a laptop because of dust. However, it may also be caused by the aging of the laser tube because the optical drive has been used for too long.

Solution:

If the disk is not read due to dust, you can wipe the focus lens surface on the laser head with cotton dipped in a small amount of distilled water. Pay attention to the unavailability of alcohol and excessive force. After the moisture is dried, close the tray. To avoid dust pollution, take out the disc and close the tray when the laptop drive is not used. When the laser tube is aging, you can adjust the power of the laser tube to solve the problem. There is usually a Small Potentiometer like a cross screw next to the laser head assembly. You can use a small screwdriver to rotate a small angle clockwise or counterclockwise until the disk can be read smoothly. Do not rotate too much to avoid burning the laser head if the power is too high.

Note:

In addition, the optical drive of the laptop has a tray on both sides for use. If the disk is loaded with too much force, it will easily cause damage to the rail and tray. Over time, it will lead to the failure to pop up or close the tray. Therefore, when placing the disc, you may wish to manually hold the tray of the optical drive, and then press the disc. There are also inferior discs that will accelerate the aging of the optical drive. Once the disc is damaged or bent, it should not be placed in the optical drive.

Fault concentration 2: keyboard

The keyboard of a laptop is one of the most intimate components with the user and the longest contact time. Therefore, the wear will also be severe. The main failures of the keyboard are: drop of the keyboard and cap, break of the keyboard bracket, and button failure. There is also a serious keyboard water problem, water is the source of life, but water may be the source of the broken name of the notebook.

Solution:

The keyboard's keycaps often fall off, as long as the keycaps are aligned with a slight force to press the position.

If the stent is broken, a new keyboard may need to be changed, unless of course it does not affect the use.

If you accidentally enter the water on the keyboard, immediately cut off the power supply and take out the battery. Do not take it slowly and shut down in the normal step. Otherwise, the notebook will be sent away when it is turned off halfway. After the power supply is cut off, the machine is reversed to avoid water flowing into the motherboard. the keyboard of most laptops is blocked by a waterproof compartment or a plastic wire board. However, if the keyboard is not reversed, the water is pervasive. Then, use a dry cloth or paper towel to dry the water on the keyboard surface. if conditions permit, remove the keyboard to dry the residual water. Finally, blow dry with cold air, should not use hot air, to prevent keyboard plastic or heat-resistant Parts of the heat deformation. It can be used only when the moisture is completely cleared.

Note:

The keyboard of the notebook occupies a large surface area of the notebook, and there are a lot of gaps, dust is also not polite to hide it, especially the GG love smoke, dust will make the feel worse or keyboard failure. Therefore, it is best to regularly or irregularly clean up the keyboard. When cleaning, you can use a soft brush that will not lose hair, such as a paint brush, to stand aside after shutting down the laptop, then, clean the gaps of the keyboard carefully, or remove the keycaps before cleaning. However, the amount of work may increase.

Fault concentration 3: Screen

There are two main types of failures on the laptop screen: self-owned defect faults and faults caused by improper use.

Faults with self-owned defects are mainly manifested in "bad points" or "color points ". A bad point is a pixel that never emits light on the screen. It usually occurs during the production process and rarely occurs during use, and it cannot be repaired. A color point is a pixel that always shows a certain color on the screen. Like a bad point, it cannot be repaired.

Screen failures caused by improper use mainly include white spots, black screens, or unstable screen display. White spots are usually caused by press or collision on the screen. If the damage is serious, they cannot be repaired. Black screen may be caused by completely damaged screen, Broken connection line, or failure to light the screen backlight. Unstable screen display is mainly caused by loose connection lines or failure of backlight.

Solution:

The LCD screen is one of the important parts of the notebook. As the only interface for communicating with people, it has the importance of a "mental window". It has a high failure rate and high technical requirements for restoration. Therefore, the author suggests that if a screen failure occurs on the laptop, it is best to send it to professional personnel for diagnosis in a timely manner. Of course, daily maintenance work is also very important.

Note:

The screen's bad points, color points, and white spots cannot be repaired. Therefore, you should pay more attention when purchasing and using the screen. For the black screen, in addition to appeal, it can also be caused by switching the display device of the notebook to the external display device mode without switching back. In this case, you only need to use the function key (FN) combination key (different brands of laptops have different keys) to switch back to the local display. If you cannot switch, you only need to restart the notebook to solve the problem.

Fault concentration 4: Battery

The size, capacity, and type of the notebook battery have undergone several generations of development. At present, most of the batteries used in laptops are MH-Ni battery or lithium battery. The battery is generally composed of a shell, battery pack, charge/discharge control and protection circuit. The battery of a laptop is very important. In actual use, there are many problems encountered in the battery of a laptop, and the main problems are the unavailability and correction. Most types of batteries have protective circuits. When the battery temperature is too high or the discharge current is too high, the battery may automatically force power off. When the temperature exceeds the preset temperature of the battery protection circuit, the Protection Circuit also automatically loses power to protect the battery and laptop.

Solution:

High temperature causes serious damage to the battery. Avoid using laptops in High Temperature environments or at high loads, in case of automatic power failure, you can take out the battery and place it in a shaded place for a moment and then restart the system. In addition, when the performance of the battery is greatly reduced, it can be fully charged and discharged several times, but note that the battery correction should not be too frequent, otherwise it will affect the life of the battery.

Note:

Battery is a consumable part. If you use a battery for several hundred times, it will be decommissioned, and the laptop battery price is not low. Generally, 800 ~ 1500 yuan. Therefore, we should pay attention to the maintenance and maintenance of the laptop battery during use.

Fault concentration 5: Interfaces

Interfaces that are most prone to failures on laptops are Nic interfaces, USB interfaces, ieee1394 interfaces, and headphone jacks, the main cause of the problem is the use of inferior plug and improper operations, mainly caused by pin damage, interface circuit burning, port surface coating rust and so on.

Solution:

The pin damage of the interface is generally caused by excessive force insertion or wrong device connection. Therefore, when accessing the device, it is best to check whether the interface matches. If you feel obvious resistance during the access process, you need to check whether the PIN is bent to avoid further bending and the pin is broken. If the pin has been obviously bent, you can use tweezers to correct it in the shutdown state. Remember to shut down first, otherwise the short circuit of the pin will cause the interface circuit to burn out.

Note:

A port is an external portal for a computer. A computer without a port is as lonely as a person without friends. It is also important to protect the port of a laptop. Currently, most laptop ports can be used with bezel. If there is no connection, close the bezel and do not let the interface touch water or corrosive things.

Perhaps the notebook has far more faults than this, and it may not appear during use. In any case, the notebook maintenance and user's usage habits will affect the notebook's life. Both users and manufacturers hope that their laptops can be used with greater peace of mind, comfort, and long-term life. Therefore, while the manufacturers strive to optimize their after-sales services, our users should also learn to maintain and maintain their laptops better. Although the manufacturer will provide users with free or paid services within one year or three years, daily maintenance and good use habits are essential to make their books longer.
