Precautions for maintaining your laptop

Do you know what is the most valuable part of your laptop? Perhaps everyone knows the answer, that is your "face"-LCD screen. The LCD (liquid Crystal display) LCD screen used by laptops has many advantages, such as "low power, no radiation, no dizziness" compared with the CRT (cathode ray tube) Cathode ray tube display used by the desktop computer. And can protect the user's eyesight to a great extent. The LCD screen is expensive, and its cost generally accounts for 40% of the cost of the entire laptop computer, and its physical properties make it the most vulnerable part of the notebook computer, and it also determines that it has a lot of extra attention than CRT. But in daily work and life, you can often see some friends of the notebook LCD incorrect habits, thus affecting its display effect or shorten the service life. So what do we notice about the laptop LCD screen in everyday use? Well, then please look for the answers you need in this article.

Notebook computer LCD can be divided into TN, STN, DSTN, HPA, TFT, of which TN, STN in the existing products have been very rarely used, we can see the basic is the use of DSTN, HPA and TFT models, which also the most common TFT. This paper is mainly for the current more mature, widely used in the wide range of TFT (Thin Film transistor), but for other types of LCD also basic application.

One, the top cover is not "Loading table"

I do not know if you have this experience: sometimes need to move a laptop, in addition to the machine, as well as the power adapter and external mouse and other objects, this time two hands are not enough. Some friends save the trouble by putting these things on top of a notebook and moving away (I've also seen a pile of books piled up on the top cover). It's easy to save the trouble, but the strength of the top cover design and manufacture of many laptops is not enough to guarantee that the deformation will not affect the LCD. You can try to squeeze the top of the notebook with your fingers, most of the corresponding parts on the notebook screen will appear water ripple phenomenon. The liquid crystal display has several layers of structure, which are: vertical linear polarizer, glass sheet, transparent x electrode, calibration layer, liquid crystal flow, calibration layer, transparent y electrode, glass sheet, horizontal linear optical device. And these materials are very fragile and very easy to damage, so once the outside of the force of the stool will be difficult to repair the LCD damage. Some notebooks take this into account and have a special design or reinforcement of the top cover. such as IBM ThinkPad some models of laptops using titanium alloy shell, and its thick and wide border design to a certain extent to protect the LCD from external shocks caused by the damage; The radian design of the top cover of Sony's R505 series, the principle is similar to the traditional Chinese arch bridge, so although the R505AFC of the top cover materials are relatively thin, but through this structure to obtain a good top-cover strength, with the hands of the screen on the back of the top screen without any water ripples appear, this design is commendable.

Second, the package selection, put Mo careless

Notebook computers are often used to carry out use, because the outdoors may often encounter windy and rainy weather, and bumps are inevitable, at this time, for your notebook to buy a good work, thick and reliable notebook bag is particularly necessary. Some notebook bags with waterproof fabric, can effectively prevent the rain on the notebook liquid crystal and other internal components of erosion damage, and thick bag can minimize the impact on the fragile LCD screen damage. The following figure is a fairly well received IBM Red dot package. Of course, it is best to avoid the rainy day to carry a notebook out and touch, Fall notebook situation (I think no one friend will be generous to take a notebook computer when the board to smash people it, hehe). Don't think it's okay to have a good bag. Fortress is often broken from the inside of Yo, notebook bag items placed also need to pay attention to, do not put the key, screwdriver and other sharp things in the bag, batteries, power adapter, external light, floppy drive and other accessories are best to classify in the bag in the small bag, Avoid squeezing the top cover of the laptop to cause the LCD to damage, while also minimizing the notebook casing being scratched and scratched. (Boss Li has done this before)

Third, the upper lid switch do not ignore

See here, some friends may say: joke! am I not even going to switch my laptop screen? In fact, due to the pursuit of frivolous, some notebooks in the design have to sacrifice the strength of the top cover. As the so-called "world's most frivolous" Toshiba Portage2000 and Sharp UM series, the strength of its top cover is worrying. Most notebooks have a plastic connection between the top and the fuselage, if the switch when the force is uneven or too large, the passage of time is likely to cause the connection shaft fracture or even detachment, LCD display and power supply line is through the connection shaft through the channel connected to the host, then it is likely to be damaged. Therefore, the correct switching method should be: In the front of the top cover opening and closing, and pay attention to uniform, as far as possible gentle.

Four, "round" is undesirable

Some friends are using laptops to make presentations, like to use your finger on the LCD screen pointing point, so that the LCD will leave your finger print, to the future of cleaning brings trouble (the specific cleaning method will be detailed in the following); Your nails may cause an irreversible scratch on the LCD; It may also cause damage to small lines and devices on the LCD, and the most common occurrence is the so-called "bad points". Some friends are accustomed to talking to each other on the screen "spit" (as in voice chatting), this habit is also undesirable. Because the human saliva is acidic, to the liquid crystal display screen has certain degree of corrosion effect. Some friends who are eager to avoid this situation, the screen is protected with film, just like the new machine in Kaifeng, but it is not recommended, because this will greatly affect the appearance of the screen.

Five, drink water to pay attention to

Many friends like to use the computer while eating, which can cause food residue to stick on the LCD screen or into the keyboard gap. In particular, some juicy, greasy food, it is difficult to avoid the splash on the LCD screen caused by difficult to clean stains; When using a notebook drink water or other beverages should also be careful, liquid if in the boot state into the LCD screen edge of the gap, the consequences are unimaginable. At the same time, try to avoid this habit for the sake of your physical health.
