Laptop is also called "portable computer, laptop, PDA or laptop", and its biggest feature is the body

With the same configuration, unchanged functions, thinner body and lighter weight, such a notebook computer can truly reflect the so-called "notebook" ^[2]

According to the size, weight and positioning of laptops, laptops can generally be divided into six categories: desktop replacement, mainstream, thin and light, ultra-portable, tablet and two-in-one computers (because of the rapid development of science and technology, this entry is only Provide mainstream configurations and models at the time).

Shopping process

First figure out what you are doing and how much you plan to spend, and then look at the notebooks of classmates, colleagues, relatives and friends to get a general understanding. Go online to learn a little about the basic laptop knowledge, or directly find someone who knows the family, classmates and friends. Can help, go to the hypermarket or the online appliance store to see the appearance, price, the number in your heart, and then take a comprehensive consideration before you can shoot.

Regarding the recognition of the brand, each brand has different series corresponding to different user needs. This is best to go to the appraisal official website to see the introduction, detailed, accurate, authoritative and reliable.

Undoubtedly in mainland China, Lenovo Computer (lenovo) is the largest brand. Asus Taiwan, Acer, Hewlett-Packard, Dell, Toshiba, Sony, Samsung, etc. are all well-known brands. They have a wide range of products, rich product types and adaptability. Different needs. Buying mainstream products of big brands is always right, and after-sales are better.

Appearance, this one has its own advantages. Choose which one you prefer. But appearance must be an important reference element.

Processor (CPU) Intel core (Core) series I3 processor, I5 processor are good, general laptop Core I3 processor is enough, in 2013 three generations of I3 have a large number of products on the market, its integrated display HD 4000 is also good performance Yes, the decisive selection collection that does not pursue graphics performance shows small heat production, long battery life, and low price.

size

Notebook size is generally 11-17 inches, the most common is 14-15 inches, which is also the most sold.

The 15-inch at home is good, the mainstream 14-inch is good, the 13-inch mobile is better, and it is not heavy. The 17-inch is not too much. Generally, a 14-15-inch notebook is a good choice. Although the 14-inch notebook is only one side larger, the air circulation in the internal space will be better. If you don't mind the 1-inch classmate, I recommend buying a 15-inch notebook.

RAM

Just know that it can be extended to 4G, as long as it comes with a few G

hard disk

Use ssd whenever possible

Notebook maintenance method

Do not use in unstable environments, such as in a car. This will cause great damage to the hard disk, and even make the hard disk scrap. The same is true in the off state. When shutting down and turning on the machine again, it is best to wait one minute before turning it on again. It is best to switch off the notebook for more than 20 seconds before moving it.
Do not use it in an environment where the temperature is too high or too low. This will have the greatest impact on the LCD and the battery. The low temperature is best not lower than 10 degrees Celsius, and the high temperature is best not higher than 30 degrees Celsius.
The notebook should be kept away from magnetic materials such as microwave ovens and speakers, which will cause great damage to the hard disk and even make the hard disk data disappear. Keep the memory away from electronic products such as mobile phones that can generate high-frequency signals.
Notebook cleaning: Notebooks are regularly cared for. Notebooks are a more delicate device, so pay attention to cleaning and nursing them regularly. For thorough cleaning, we should first power off the laptop and then remove the battery from it. When cleaning the LCD screen, it is best to wipe it gently with a soft, lint-free cloth moistened with water. There is no need to buy special laptop cleaners. When cleaning the keyboard, first use a vacuum cleaner with a nozzle with the smallest and softest brush to clean the dust between the key gaps, and then wipe the keycap with a soft cloth slightly moistened, and use a piece to dry immediately after finishing one Wipe the cloth dry, remember not to let a drop of liquid penetrate the inside of the case. Also, do not use corrosive liquids to clean your laptop, let alone alcohol.

Notebook waterproof

Water is the most direct killer of laptops, but many people will easily ignore many potential "waters". As you know, due to the small size of the notebook motherboard, the integration is much higher than that of the desktop motherboard, which leads to higher production costs. If the motherboard fails, the cost of replacing the motherboard generally accounts for about one-third of the price of the whole machine, because such accidents are generally human failures and are not covered by the warranty, so the repair costs can be astounding.

How to avoid being hurt by a water killer? First, keep the notebook environment dry. Second, try to keep a certain distance from the water while using the notebook, such as drinking tea while using the notebook, using the notebook when your hands are wet, etc. are bad habits, it is easy

Mainstream laptop Water the notebook and damage it.

Water can easily damage the notebook motherboard

Don't panic if the notebook is flooded with sudden conditions. First, press the power button at the fastest speed to cut off the power. (Do not turn off the machine in the usual way, otherwise the motherboard may have been short-circuited and burned. Then, remove the notebook battery (this is the first one that needs to be removed, and the action must be fast) To prevent the battery from continuing to power on the motherboard. Tilt the notebook over immediately to allow the liquid in it to flow out. Some articles said that using a hair dryer to dry the notebook, some friends seem to follow suit, but this method cannot be used, maybe everyone I have never seen the internal structure of a notebook. There are basically many plastic components inside the notebook. If you use a hair dryer to blow them, it is easy to cause these plastic components to be deformed by heat, making the situation worse. Even if you blow, you must use cold air. blow.

You can dry the notebook in a ventilated place for three or four days to allow the water in the body to evaporate naturally. After three or four days, install the battery and power supply, and try to run it. If not, you can only send it for repair. Some friends may splash water on the keyboard. Compared to the water on the front motherboard, it can be said that it is much luck. In order to prevent water from further damaging the keyboard printed circuit, you should immediately turn off the power and remove the battery. Then turn the notebook upside down at 180 degrees and let the water in the keyboard flow out as much as possible. After the water is completely clean, turn on the power and try to see if all the keycaps are completely effective. If you are out of luck, the main board will be unpredictable, and it will only be sent to a repair station for repair.

Notebook anti-finger static

People's hands do a lot of things a day, and it's extremely easy to get dirty. When using such a finger to operate the touchpad, the coating on it will disappear quickly, which will seriously shorten the service life. In the past, the keyboard of the notebook will be worn away, or it will be scrapped. The most susceptible to static electricity is the notebook interface, especially the USB, MODEM, network card and other interfaces that often need to be plugged. When plugging or unplugging these interfaces in winter, it is best not to operate with power on. Try not to let clothing or your body touch the metal part of the interface. Also pay attention to the USB and other interfaces to be straightened and plugged in, so that the power cord is in Data cables that were previously connected help prevent static electricity.

If you find a crackling sound when undressing, it is best to wash your hands before touching the laptop to avoid passing the spark of love to the laptop. Do not put U-disks, MP3 and other electronic products in the pockets of cotton jackets or sweaters in winter. This place has very large static electricity, which not only easily damages U-disks, MP3 and other equipment, but also easily damages notebook interfaces. If the static electricity only causes a lot of dust on the LCD display, you can use a special small brush to clean it, but if the static electricity causes the laptop to be damaged, you have to send it for repair.

How to avoid the harm caused by static electricity? First, contact the notebook with the static electricity of the human body as small as possible, especially some interfaces and internal components of the notebook. If you need to touch the components inside the notebook, if you install a memory module and touch the water pipe or grounding device, you can eliminate your own static electricity. Secondly, it is better not to place other electromagnetic devices around the notebook. Devices such as mobile phone chargers should be kept away from the notebook as much as possible.

Laptop anti-condensation

In low temperature seasons, condensed water is the most easily overlooked laptop killer. Many people do not pay attention to the details of using and placing the notebook, which may cause devastating damage to the notebook.

A friend wearing glasses may feel very deep. In winter, when you enter a warm room from the outside, a layer of water vapor will appear on the glasses, which is condensed water. The notebook is also a reason, especially for the notebook with a metal case, the chance of generating condensate will be greater, and the amount will be more. In addition to the surface, the inside of the machine may also cause this phenomenon, so do not underestimate this thin layer of condensate, this layer of condensate may completely hurt the heart of the notebook. Condensate is everywhere, as long as it is in contact with the air, condensate may be generated, including important parts such as the motherboard and CPU. If the system is turned on at this time, the consequences can be imagined.

The best way to avoid condensed water is, first of all, not to make the notebook too cold, and to buy a cotton inner case for the notebook. Secondly, when the notebook is in a relatively cold outdoor environment for a long time, once you enter a warm and humid room, you must wait patiently for a while to allow the notebook to slowly warm up in its inner bag. Do not use the notebook immediately. There will be no instantaneous temperature difference on the surface, so no condensation will be generated. And if many friends do nt have a cotton inner bag, they can also just open a small opening of the laptop backpack after entering the room, let the air circulate and slowly warm up, as long as there is no large temperature difference, there will be no condensation.

Notebook battery use

Attentive notebook users like to remove the battery from the machine when they are not in use. This can prevent repeated charging of the battery from affecting battery life and reduce the weight of the notebook. It is best not to save, for the sake of data security, it is best to put the battery back on the laptop, otherwise the data will be "ruthlessly" lost by accident. In fact, this approach is not worth the money. There are not so many problems installing the battery on the machine. The batteries use lithium-ion batteries. The memory effect of the battery is already very small. In addition, most of the batteries have smart chips inside. This small chip can not only control the battery charge but also check whether the battery It needs to be charged. Generally, it will start to charge only when the power is below 90% to 95%, so the battery will not always be charged when it is placed on the notebook.

Ideally, you should try to keep your battery charge between 20% and 80%. Remember, these are the best ways to unplug your machine before the battery is 100% charged. In addition, do not wait until the battery is dead before charging. Try to keep your laptop cold. Computer shutdown charging is the best charging method. When you turn on your laptop, you should unplug the battery from your computer and then plug it in again. Although this method is inconvenient, if the battery is fully charged and then plugged in, it will cause great damage to your battery.

After years of research and development, the problem of overcharging the battery has been basically solved. Unlike the early nickel-metal hydride batteries, if the commonly used lithium batteries often completely discharge the stored power, then the battery life will be greatly shortened and manifested. The reason is that the battery pack capacity has dropped significantly. So some friends will ask how much power should the battery retain? According to the experience of many people, it is best not to leave the remaining power of the battery pack below 5% of the total power. Laptops that can view battery information (including total design capacity, actual total capacity, number of recharges, manufacturers, health, etc.) have two major brands, IBM and Sony. Other brands can only rely on third-party software to achieve it.

Some friends may not move their laptops too much, and the battery will be left at home for a long time, and the battery may be fully charged, and then placed aside. In fact, this is not right, so that the battery cells in the battery pack will be relentlessly aged. The battery should not be fully charged, it only needs to be charged to about 40% to 65% of the total power. Remove the charged battery, wrap it in plastic wrap, and place it in a well-ventilated and cool place away from direct sunlight.

Notebook tips

1. When you are dealing with text content, it is very wise to reduce some brightness and contrast. This can save a lot of power resources. You must know that the screen of the notebook can account for as much as 30% of the overall power consumption! At the same time, when processing text content, reasonable brightness and contrast will not irritate the eye too much, and it can also protect eyesight.

2. The new-generation I5 and I7 processors have Turbo frequency function. In fact, it is the automatic overclocking within the manufacturer's allowable range, but it is hard to detect the increase of 5-10% performance. The price paid is indeed an increase in power consumption. And terrible heat dissipation. Generally, the maximum performance is adjusted to 99% in the CPU performance of power management, so that the Turbo function will not be automatically enabled.

3. When the notebook is not used temporarily, the standby function is very convenient. It can be started by covering the screen, but it also consumes power. Use hibernation instead. The startup speed is only ten seconds slower than standby. However, this function does not consume power and saves a little bit.

4. If you do not use the battery for a long time, only use AC power, but it is best to charge the battery once a month. Note that the battery is fully charged (at least 60%) before unplugging. It is easy to use the battery for a long time if it is discharged. "Starve" the battery, because the battery is slightly discharged even when it is removed.

5. Heat dissipation. So summer use feels hot, then it is best to use cooling (fan) equipment; ^[2] ^[4]

6, maintenance is usually pay attention to keep the computer clean, try not to use in dusty places. If there is no film on the LCD screen, you don't need to wipe it if it is dirty. The more you rub it, the easier it will be.
