Because of the large function, small size, small weight, the notebook is increasingly favored by consumers, but it is because the notebook is small, the integration is high, making the laptop have a lot of complicated desktops, and more faults And not as easy as a desktop. However, in many faults, most of them are not caused by the quality of the machine itself, but because the user is not operating in the process of use. So, in the process of use, which parts of the notebook are more "fragile"? Why is they "fragile"? Whether we have a bundle for "fragile"? This article will give you a answer.
One of the fault concentration: CD drive
[Blocked Advertising] The optical drive failure of the notebook is mainly manifesting that when the disk is prompted or not, or the reading time is very long and the data cannot be read.
The structure of the laptop drive is more precise than the beater light, and the components such as the laser head are loaded directly on the tray, and therefore, it is more sensitive to dust and stains, and the laptop optical drive often appears. Not reading the phenomenon is much caused by dust. However, it may also be due to the time of use of the optical drive to cause laser tube aging.
Solution:
For the non-reading failure caused by dust, the focus lens surface on the laser head can be wiped with a small amount of distilled water. Note that alcohol is not available, and it is not too much to be excessive, and the tray can be held in the rear of the water. In order to avoid dust pollution, the laptop should take the disc and turn off the tray when not in use. For the case of laser tube aging, it can be solved by adjusting the power of the laser tube. The side of the laser head assembly typically has a small potentiometer like a cross screw, and a small angle can be rotated with a small screw knife or counterclockwise until the disk can be read. Note that there is too much to rotate, so as avoiding too much power and burn the laser head.
Precautions:
In addition, the optical drive of the laptop has a guide rail for tray on both sides. If the loading disc is loaded too much, it is easy to cause damage to the rail and the tray, which will cause the tray that cannot be populated or closed. Therefore, when placing an optical disc, you may wish to hold the drive with a hand, and then press the disc. There is also a inferior disc that will also speed up the old-driven age. Once the disc is found to be damaged or curved, it should not put it in the optical drive.
Fault Concentration 2: Keyboard
The keyboard of the laptop is one of the components that are closest to the user, but also the longest contact time. Therefore, wear will be relatively powerful. The main failure of the keyboard is: keycap falling off, keyboard bracket breaks, buttons failing, etc. There is also a serious keyboard water problem, water is the source of life, but water may be the source of the name of the notebook.
Solution:
The keyboard of the keyboard is often seen, as long as the keycap alignment position is slightly pressed.
If the bracket fracture may need to replace the new keyboard, there is of course excluding the case where the use is not affected.
If it is inadvertently bile water, the first time should be cut off immediately, take out the battery, do not slowly swallow according to normal steps, otherwise it will be sent to the notebook. After cutting off the power, turn the machine to avoid water to continue into the motherboard. Most of the keyboards of most notebooks have waterproof compacts or plastic wire plates, but if they don't turn, water is not angled. Then use the dry cloth or tissue to suck the water on the surface of the keyboard, and the keyboard is allowed to remove the remaining water. Finally, the cold wind is blown, and it is not advisable to use hot air to prevent the heating or non-heat-resistant portion. You can use it when you make sure the moisture is completely cleared.
Precautions:
The keyboard of the notebook occupies a large surface area of the notebook, and there are very gaps, dust is also unfair, especially the GG who loves smoking, the dust will make the hand touch or keyboard failure. Therefore, it is best to clean the keyboard regularly or irregularly, when cleaning up, you can use a more soft to the brush, such as a oil brush, etc., turn the laptop, then connect the laptop, then carefully clean the gap of the keyboard. Or dismantle the keycap and then clean it, but the volume will be a lot. Three fault concentration: screen
The main failure of the laptop screen can be two categories: ie the self-defect failure and the failure caused by improper use.
The self-deficient failure is mainly manifested as: "bad point" or "color point". The bad point refers to a pixel point that never shines on the screen. It is usually in the production process, and few things will appear during use, and bad points are generally unpaid. The color point is the pixel point that has always been present on the screen. Like a bad point, it is not repaired.
Since the screen failure caused by improper use is mainly: "white spot" or "black screen" or screen display is unstable. White spots are usually due to the pressure or collision of the screen, and if the damage is severe, it is generally unpackable. Black screen may be that the screen is completely corrupted, the connection line is disconnected, or the screen backlight does not light. The screen display is mainly due to the loose line or the backlight failure.
Solution:
The liquid crystal display is one of the important components of the notebook. As the only interface that communicates with people, there is an importance of "soul window", which is relatively high, and the technical requirements for repair are also high. Therefore, the author suggested that once the laptop appears on the screen fault problem, it is best to give professional diagnosis in time, of course, daily maintenance work is also very important.
Precautions:
For the bad point, color point and white spots of the screen, it is generally unpackable, so the user should pay more attention to purchasing and use. For black screens, in addition to the possible reasons for appeals, it can also be caused by switching the display device of the notebook to the external display device mode without switching. Simply use the function key (FN) combination key (different brands of laptop's combination of laptops) to switch back to this display, if you can't switch, you can solve the problem with the notebook.
Fourth 4: Battery
The notebook battery has undergone several generations of development, whether it is a lot of changes in volume, capacity, and types. The battery is currently applied to the battery of the laptop or a lithium battery, and the battery is generally composed of housing, battery pack, charge and discharge control, and protection circuit. The battery of the laptop is very important. In actual use, the problem encountered by the laptop battery is also more, the main problem is concentrated in use and correction. Most models of the batteries are protected circuits. When the battery temperature is too high or the discharge current is too large, the battery may automatically power off. When the temperature exceeds the battery protection circuit preset, the protection circuit will also automatically power off to protect the battery and laptop.
Solution:
High temperature damage to the battery is very large, should try to avoid using a laptop in a high temperature environment, or high-load laptop, and the battery can be removed after a cool place after a moment of cooling. In addition, when the performance of the battery has declined, it can be fully charged, discharges several times, but it is necessary to note that the battery correction should not be too frequent, otherwise it will affect the life of the battery.
Precautions:
Battery belongs to the easy-consuming component, and hundreds of times will be scrapped, and the price of the laptop battery is not low, usually take 800 to 1500 yuan. So we should pay attention to the maintenance and maintenance of the laptop battery during use.
Five Fifth: Interface
The most prone to faults on the laptop is a network card interface, a USB interface, IEEE1394 interface, and headphone jack. The main reason for the problem is to use inferior plugs and improper operations, mainly manifesting, pin damage, interface circuit Burning, the surface of the port is rusted. Solution:
The pin damage of the interface is generally caused by excessive or after the insertion, so it is best to see if the interface is matched, if you feel obvious resistance during access, you need to look at it. Whether the pin is curved to avoid further bending and break the pin. If the pin is already curved, you can positively dial it with tweezers in a shutdown state, remember to shut down first, otherwise the short circuit of the pin will cause the interface circuit to burn.
Precautions:
The port is a computer-out portal, and the computer that has no port is like a person who has no friends, and the port of protecting the notebook is also an important thing. Most of the ports of most notebooks are equipped with a baffle, and the baffles should be combined without connecting, and do not let the interface touch the water or corrosive things.
Perhaps the failure of the notebook is far more than this, or maybe in the process of use, no matter how, the care of the notebook and the user's usage habits will affect the life of the notebook. User and vendors hope that the notebook can be more assured, more comfortable, and longer, so in the manufacturer's efforts to optimize their after-sales service, our users should better learn to maintain and maintain notebooks. Although the manufacturer will provide users with free or charged services for users, they are essential to make their own book longer, daily maintenance and good usage habits are essential.
