Low temperature problem of notebook computer

Five Taboos of Using Laptop Computers in Winter

One of the taboos! Don't use your notebook outdoors.

Many friends like to watch movies in the Woods, surf the Internet with their sisters by the river and show off their books in public on the bus. In winter, these habits should be changed, because laptops are very afraid of cold. What, you want to add a cotton-padded jacket to your notebook? Put a scarf around your notebook? Don't call me if the notebook is smoking and getting hot, even if it makes the neighbors call 1 19 to put out the fire.

The first reason for not using the notebook outdoors in winter is that low temperature will damage the TFT screen of the notebook. Generally speaking, the optimum temperature for using TFT screen is 40 degrees to 10 degrees. If the temperature exceeds this range, the color of TFT screen will become abnormal and accelerate aging. If the TFT screen is used at too low a temperature, there may be bad spots and permanent damage to the TFT screen. Friends in the northeast may have this experience. In the cold outdoors, the screen of the mobile phone will become very bright and pale. In fact, this is the fact that the liquid crystal material in the TFT screen has begun to deteriorate. If you really want to experience why the TFT screen below is called "liquid crystal" screen, you can leave your notebook outside and freeze it overnight. When the liquid in the screen becomes crystal, your screen may become a famous ultra-black crystal screen or a high-brightness screen, and no matter how you toss it, it will always be the same color. For the health of your TFT screen, give up using your notebook outdoors in winter.

The second reason for not using the notebook outdoors in winter is that low temperature will damage the battery of the notebook. At present, most notebook computers use lithium-ion batteries, which have the advantages of heavy weight and large capacity, but also bring the disadvantage of being very afraid of cold. Generally, the capacity of civil lithium batteries will be reduced by 20% at zero, and it may be only about half at MINUS ten degrees. Friends in the north all know that in winter, if the phone is out of power, put it in your arms to warm up and it can be used for a while. This is because the battery temperature is too low to discharge. Once or twice use may not have much impact on the battery life, but long-term use may cause permanent damage to the battery.

The third reason why you don't use your notebook outdoors in winter is that it is not pleasant at all and is easy to cause misunderstanding. Think of yourself blowing alone in the cold wind, the river water in the river has turned into hard ice, the lush young trees have turned into suddenly glowing branches, and a few dead leaves have flown by from time to time. I know you have this hobby, but I didn't know you thought you were kicked out of the house by your wife. Besides, it's so cold in winter that my hands are probably shaking with cold. When chatting with my little sister, I accidentally made it: Sister ~ ~ Sister ~ ~ Sister, did you eat early ~ ~ Good morning ~ ~ Good morning! Little sister must think you are a stutterer and hemiplegia. For the sake of your health and your glorious image, it is best not to use your notebook outside the city in winter.

The second taboo is to prevent condensation!

I also teach you a good way to clean your notebook. You can put it outdoors for about ten minutes in winter until the surface of the notebook feels very cold. Then take the notebook to a warm city, and a layer of condensed water will form on the surface of the notebook in about two minutes. At this time, you can pick up a rag and quickly wipe the notebook. If you feel that the water is not enough, you can spit a few mouthfuls of liquid. Another advantage of cleaning the machine in this way is that it can not only clean the surface of the machine, but also clean several components inside the machine, such as fan port, keyboard, motherboard and so on. After cleaning, just throw them out with the dryer.

The above method is actually joking with you, but have you noticed the problem of condensed water? The reason for the formation of condensed water is that when the notebook surface just enters the warm room from the cold outdoor, there is a large temperature difference on the surface instantly, which leads to the condensation of indoor water vapor on the notebook surface, especially the notebook computer with metal shell. Don't underestimate this thin layer of condensed water, which may completely hurt the heart of the notebook. Condensed water can be described as pervasive, as long as it comes into contact with air, it may be produced, including your motherboard, CPU and other important components. I don't need to say more about the consequences of a layer of water in these parts.

The best way to prevent the notebook from being too cold is to buy a cotton inner bag for the notebook. Don't be so stingy. You bought a lot of clothes, but you didn't buy one for your notebook. In fact, the thick cotton inner bag and the wind-resistant leather outer bag can at least ensure that the surface of the notebook will not be too cold for two hours outdoors. When you first enter the room, you can open the inner bag and let the notebook heat up slowly in the inner bag, so that there will be no instantaneous temperature difference on the surface, so there will be no condensed water. If there is no cotton inner bag, just open a small mouth of the notebook backpack after entering the room, let the air circulate and slowly heat up. As long as the temperature difference is not big, there will be no condensed water.

Finally, if there is condensed water on the surface of the notebook, don't turn it on first. As long as the motherboard is not electrified, there will be a small amount of condensed water, and there will be no big problem. In addition, don't open the notebook screen when there is condensed water on the TFT screen, because the condensed water may flow down after the screen is erected and flow into the screen along the gap at the bottom of the screen. Many high-voltage circuits on the laptop screen are very dangerous here.

Third, avoid anti-static stealth killer!

Ever heard of the notebook stealth killer? Are you afraid that your notebook will be killed invisibly? Have you ever imagined what it's like to suddenly hang up your notebook for no reason? If you don't want these things to happen, start paying attention to static electricity immediately. Notebook computer is a very complicated electronic product. This guy looks very strong, but his body is very weak. What he fears most is static electricity.

Winter is the peak of static electricity, the invisible killer. After autumn, the weather in the north will become drier and drier. Not only is the mouth thirsty in winter, but the skin feels dry. In addition, after winter, clothes are gradually increasing, including sweaters, wool gloves, cotton-padded jackets and so on. Don't underestimate these clothes. Now all the so-called lycra cotton, sweaters, wool and other textile materials are acrylic fibers. This thing has no other advantages, but it is easy to generate static electricity, and it will rattle when you take off your clothes, and there are sparks all over your body. This static electricity will be stored in your body until you come into contact with something lower than your potential, such as a laptop, MP3 and so on. I don't need to tell you the final result.

Notebook interfaces are most vulnerable to electrostatic persecution in winter, especially USB, MODEM, network card and other interfaces that often need to be plugged and unplugged. When plugging and unplugging these interfaces in winter, it is best not to operate with electricity, and try not to let clothes or bodies touch the metal parts of the interfaces. In addition, when hot plugging, pay attention to aligning and plugging USB and other interfaces, so that the power cord is connected before the data cable, which helps to prevent static electricity. If you find a crackling sound when undressing, you'd better wash your hands before touching the laptop to avoid transferring the spark of love to the laptop. Finally, I remind you not to put electronic products such as USB flash drive and MP3 in the pocket of cotton-padded jacket or sweater in winter. This place is very quiet, which is not only easy to damage your USB flash drive, MP3 and other equipment, but also easy to damage your laptop interface.

Taboo four, don't block the notebook!

One day, I stomped into bed and wanted to peek at a movie. I always feel something special when I look at it. At first I thought it was smelly feet or socks, but later I thought it was wrong. Why do I still smell a little hot iron plate Later, I didn't look at it, only to find that because the bedding on the bed is too soft, the notebook is deeply trapped in the bedding, and the exhaust port of the notebook cooling fan is tightly blocked, which can be said to be airtight. In addition, the insulation effect of the bedding is very good, so the position of the notebook CPU is very hot, making my fingers all red marks. Fortunately, the quality of this notebook is good, otherwise I would have died.

There are not a few people who like to lie in bed and hide under the covers to play with notebooks in winter. If you have the habit of using notebooks like this, be careful. In winter, the temperature in the city is relatively low, so many people ignore the problem of notebook heat dissipation, because lying in bed often leads to notebook failure because the fan mouth is blocked. A notebook that can't effectively dissipate heat becomes a small stove as soon as it is opened. Burning out a notebook is a trivial matter. How bad it would be if you accidentally started a fire and then burned the flowers and plants.

In order to make the notebook have a certain cooling space on the bedding, a hard object such as a flat plate can be placed under the notebook. If you find it inconvenient to use the board, you can also pad some thick magazines under your notebook. Pay attention to the position of the air outlet and air inlet of the notebook, and be sure to keep this air duct open. Now the notebook fans are running intelligently, so if you find that the notebook fans are running for a long time, be sure to check whether the wind path is smooth. If your conditions permit, you can buy a small notebook table specially designed for using notebooks in bed, which not only solves the heat dissipation problem, but also is very convenient to use. In addition, I would also like to remind you that if you find that the notebook fan is blocked and the body is very hot, don't turn it off immediately. Just stop all operations and take the notebook to a place where ventilation can be guaranteed. If it is turned off immediately, the internal fan will also stop working, and the heat inside will not be dissipated for a long time, so it can be quickly taken away by the fan.

The fifth taboo, don't break the notebook's reserve rations!

Careful notebook users like to remove the battery from the machine when not in use, which can avoid the battery life being affected by repeated charging and reduce the weight of the notebook. After winter, I suggest you don't save money. For your data security and your love, you'd better put the battery back in your notebook to avoid losing data and even love.

Will the data be lost when the battery is removed? Even affect love? Actually, I'm not exaggerating at all Because there is no indoor heating in early winter, high-power equipment such as electric stove and electric heater will come in handy. These high-power devices are very likely to cause circuit overload and power failure, and sudden power failure in early winter in the north is almost common. Imagine that you spent an afternoon writing a love letter to your little sister. When you finally decided whether to use "love your baby" or "love your heart", it suddenly got dark, and all your efforts in the afternoon were in vain. If you have a battery on your machine, that's fine. At this time, the battery is equivalent to UPS uninterrupted power supply. Although it is not always uninterrupted, it is enough to bring a glimmer of light to your love.

There are not so many problems in installing batteries on the machine. The current batteries are all lithium-ion batteries, and the memory effect of the batteries is very small. In addition, most batteries are equipped with smart chips, which can not only control the charging amount of batteries, but also detect whether batteries need to be charged. Generally, charging will only start when the power is lower than 90% to 95%, so the battery will not always be in a floating state when it is placed on the notebook. In contrast, the inconvenience caused by no battery is more costly. Didn't you say that gold is valuable and love is priceless? Your battery is not as valuable as gold, let alone love. Do you want to stay in love? Then don't be too stingy, install the battery and use it safely. Don't cut off the notebook's reserve rations in winter.
