I like a notebook very much, but it's so expensive.

it is adopted in the models over p>14 inches. For many students, Athlon XP-M notebook with low price and sufficient quantity is a good choice.

The Crusoe of Quanmeida is a mobile processor with ultra-low power consumption, which is like adopting software to simulate the processing algorithm of hardware, so the number of transistors is greatly reduced and the power consumption is controlled very low, but the corresponding performance is not high. However, it is adopted in many mini-notebook computers, which are 5.6-inch and 8.9-inch. It is not a product that requires performance, but super portability is its pursuit, so it also has it. In addition, Quanmeida's latest Efficeon processor will be released soon, and we expect this ultra-low power mobile processor to improve its performance.

Chipset:

The motherboard chipset is also a very important part of the notebook computer, which is closely related to the performance and overall power consumption control. The non-Intel mobile chipset with the best comprehensive performance on notebook computers is the best in memory, disk performance and power management, and other competitors can't compete with it in this field, which is one of the reasons why Intel is far ahead in the notebook field. In addition, SiS, Ali and Ati North Bridge+Ali South Bridge are common on notebook computer chipsets, and others are VIA, but they generally appear in notebook computers using AMD processors. Although these chips exist in the market, they have little share in actual products and often appear in some low-priced notebooks.

It should be noted that some ultra-low-cost notebooks use desktop accessories in chipset, processor and memory. Although this is low-cost and cheap, the overall stability is doubtful, and the internal design and heat dissipation are worrying. Moreover, there is no ——PC card slot, which is an important expansion slot for notebooks. Strictly speaking, it cannot be regarded as a notebook computer. Users should pay attention to this when buying low-cost notebooks.

Memory:

The memory of a notebook computer is completely different from that of a desktop computer, and the price is much more expensive than that of a common desktop computer, but its small size is beneficial to the internal design of a notebook computer. At present, DDRAM is also widely used in notebook memory, and SDRAM is basically out of date, which will only be used when upgrading old computers. Therefore, when we buy notebook computers, the memory is generally DDRAM specification, one is the more common SO DIMM notebook memory; One is Micro-Dimm memory. Micro-Dimm memory is generally used in ultra-thin notebooks, which is half smaller than the standard SO DIMM memory and very expensive. Notebook memory does not require high speed, and it pursues stable operation. Therefore, at present, the notebook memory with the highest specification supported by notebook computer only reaches DDR333. However, due to the speed limitation of notebook hard disk, notebook computer relies heavily on memory. Appropriate configuration of high-capacity memory will obviously help to improve the overall speed of notebook computer.

hard disk:

The hard disk of notebook computer can be said to be the slowest developing component in notebook computer, and its speed has not made a qualitative leap for a long time. At present, the specification of 42 rpm is still widely adopted, and the beginning of 54 rpm appears in some high-end notebook products. Although the 72 rpm notebook hard disk has been released, due to the maturity of technology, few notebook computers are adopted at present. At present, the size of notebook hard disk is divided into 2.5-inch and 1.8-inch, and the maximum capacity of 2.5-inch notebook hard disk has reached 8GB, which is also widely used in notebook computers. However, the 1.8-inch notebook hard disk has a maximum capacity of 4GB and a maximum rotation speed of only 4,2 rpm, which is adopted by some extremely thin notebook computers (such as TOSHIBA R1, SONY X55 and other extremely thin products), which is expensive and difficult to upgrade.

Mobile display chip:

With the increasing performance of notebook computers, games have become an entertainment function of notebook computers. The field of mobile graphics cards is still dominated by ATi. Although the rising star nVidia is catching up, it lags behind ATi in overall power consumption and performance. At present, the strongest mobile graphics cards are ATI Mobility Radeon 97 and nVidia Geforce FX Go565. Although these two graphics cards have strong performance, they also consume a lot of power. They are generally used in mobile multimedia audio-visual center-type notebook computers or desktop replacement computers, and are of course the best choice for users who play games. In addition, some other independent graphics cards also have strong 3D performance. Mobility Radeon 96, Mobility Radeon 9, Geforce FX Go52 and Geforce 4 Go44 are all good mobile display chips, and their performance is arranged as follows: Mobility radeon 96 >: Geforce Go52> Mobility Radeon 9> Geforce Go44> Mobility Radeon, its power consumption is generally inversely proportional to performance, so they all appear in different positioning models.

In addition, there is another force that can't be ignored in the notebook display field. They are integrated graphics cards, which have the lowest power consumption and good 2D display effect, so they are widely used in business notebooks and thin notebooks, and even can be said to be the absolute main force in the mobile display field. At present, the performance ranking of mainstream integrated display chip chipsets: Intel 855GME chipset >: ATI IGP7 series integrated chipset >: Intel 855GM chipset >: ATI IGP3 series integrated chipset >: Intel 852MG chipset >: SIS65M> Intel 83MG chipset. Intel's latest 855GME chipset integrated display chip, with performance equivalent to ATI Mobility Radeon 75, is the best integrated display chip chipset at present. In addition, we should also pay attention to the memory. All integrated display chips use the main memory as the memory. When using it, we should consider the size of the set memory. If it is too small, it will affect the display performance. If it takes up too much main memory, it will lead to too small main memory and affect the overall performance.

network equipment:

the network equipment of notebook computers has become the ultimate configuration of notebook computers. Centrino has vigorously promoted its "wireless infinity" (labeled as wireless network card), and it is a smash hit. At present, notebooks are equipped with a V92 modem and a 1/1M adaptive Ethernet card as standard, which is the minimum network equipment standard for notebooks at present. Users must pay attention to whether these two devices are complete when purchasing, otherwise, in the future. In addition, with the popularity of Centrino, standard wireless network card has become a feature of notebook computers. At present, most mid-to high-end notebook computers are equipped with wireless network cards, which can bring great convenience to users. With the laying of wireless networks, many public occasions have covered wireless local area networks, which brings great convenience to notebooks with wireless network cards. Of course, standard wireless network cards will raise the price of the whole machine, but for the cost of future upgrades, standard wireless network cards are more cost-effective.

display screen:

The display screen of a notebook computer can be said to be one of the most important components, and the size of the display screen directly affects the size of the notebook computer. At present, the notebook types can be divided into: 8.9-inch mini notebook, 1.6-inch ultra-light thin notebook, 12.1-inch thin notebook, 14.1-inch full-size notebook, 15-inch and 17-inch desktop replacement notebook. Therefore, the size of the screen is also an important factor for users to buy laptops, depending on what type of notebook you need. The display screen is also a big power consumer of notebook computers, and its power consumption also determines the use time of notebook computers, and its picture quality directly affects the mood of notebook users, so an excellent display screen is something that users should pay great attention to when purchasing notebook computers.

Key points of purchasing notebook computers:

In fact, many friends who buy notebook computers are in a hurry when they are impulsive. They have not analyzed their own needs before buying, nor have they fully understood the various characteristics of notebook computers, so they are eager to start, which leads to the feeling that the products they buy are not as good as their ideals in the future and regret their original decision.

Before purchasing a notebook computer rationally, it is necessary to make a full analysis, and we should have a clear understanding of both our own needs and the characteristics of the product. However, many users fail to do this when purchasing, but listen to advertisements or other people's opinions, and unilaterally pursue the weight, appearance and brand of the model, and finally buy products that are not suitable for them, which makes them extremely annoyed.

like other things, notebook computer products are not perfect, but each user's needs are different, and the positioning and functions of each notebook computer are different. Only after fully understanding their own needs and product characteristics, can they choose products with a clear aim and buy the machine that suits them best with the most reasonable money.

ask yourself whether you need a notebook or not

first, ask yourself what you need a notebook for? If you want to show off, I still advise you to give up this idea immediately. The notebook computer products are updated and eliminated too quickly. Maybe the notebook you bought for 1, yuan will be eliminated after half a year, and you will regret the price you paid for you.

If you are completely unfamiliar with computers and only use them at home, it's ok to choose a notebook, but you should consider that you can buy a desktop with outstanding performance in all aspects at half the price of a notebook, and it is more convenient to upgrade in the future, so we think your first choice should be a desktop.

so what kind of people are suitable for buying laptops? Of course, if the laptop brings convenience and pleasure to your work, study and life, then you can choose it without hesitation. For example: business people who travel frequently, college students, programmers and the second computer at home.

Know your needs

What kind of notebook do you want? What is it mainly used for? As long as you understand these two questions, you won't be aimless and at a loss when choosing products. If you are a business person and often travel, then a stable and light business notebook will be your best choice; If you are a student, you may pay more attention to the price, but the fashionable style is loved by every young person, so you can choose some notebooks with strong multimedia functions for the middle and low end. These notebooks have good performance in all aspects and are fashionable in appearance, but because students don't need to carry notebooks often, they can be less demanding in terms of weight, so there are more choices for the price of such products; If you choose a notebook for office or home use, a desktop replacement notebook with good comfort and high overall performance is your good choice. Of course, everyone's needs are complex and diverse. Ultra-thin notebooks and multimedia notebooks that emphasize audio-visual functions are all launched for different users. As long as users seriously consider this issue before buying, I believe you will have a general direction in mind, and then know the characteristics of each product in detail after selecting the scope, and it will not be difficult to pick out the product that suits you best.

Know your own budget

The price of notebook computers varies greatly. Even products with the same positioning and basically the same configuration will have different prices due to different brands. Therefore, it is very important to make your own budget before purchasing a notebook, and don't modify it easily after making the budget.

and this budget had better have two price points, one is your ideal price point, and the other is the highest price point that you are willing (able) to bear. In the actual purchase, use the ideal price first. Only when you find a model that really suits you, but the price is expensive, will you consider the highest price, but in any case, don't exceed your highest price, and don't trust the recommendation and inducement of the sales staff to let go of the scale, so that the product you buy may eventually become a heavy burden for you and pay a high price for unnecessary functions.

and after determining the purchase model, it's best to know the price quotations of as many products as possible from various channels, and then ask the buyers after determining a more realistic price. It won't hurt to ask more, and finally bargain at the most realistic one. The actual price that can be concluded will often be 5-1% lower than the price of the merchants, which depends on your bargaining ability. If the price is satisfied, you can sell it. If the price is not satisfied, don't rush to sell it. After all, the price of notebook computers is always falling, and there will always be surprises when you come a few more times.

Summary:

Notebook computer is a diversified product, so users must be clear about their purchase intention before buying, adhere to the principle of "enough is good", do not blindly pursue the latest technology, the most fashionable shape and the strongest performance, and don't be too brand-conscious, analyze and choose rationally, so that they will definitely choose a product that satisfies them.

In addition, because the domestic notebook market is not mature at present, the after-sales service of notebook computers is a headache. Therefore, we should pay attention to this problem before buying, and regard it as an important factor in purchasing machines. Choose reputable brands, fill in clear warranty documents when buying, determine the warranty time, and strive for the longest warranty period if possible, so that users can use notebooks without worries.

Buying notebooks is like buying brand-name machines, and it is easy to walk into the "trap" set by merchants. Even if you recite the online evaluation report by heart, it is hard to resist the ogling of plmm, a local store, and the small mouth that can tell the dead alive! Therefore, you should not only be familiar with the technical parameters and indicators of the products you want to buy, but also practice to the highest level of "passing through a hundred flowers without touching your body"! (Whispering: "Why do you talk so much nonsense every time! Kill! " ）。 After I resisted countless MM's saliva, I summed up the following misunderstandings in notebook purchase. I hope you will pay attention to them:

The first misunderstanding: the misunderstanding of advertising and promotion

This is the easiest misunderstanding to walk into, and it is also the trap that salesgirls are best at. Generally speaking, businesses that act as notebook agents and salespeople don't know enough about the technical trends and electronic fashions in the industry, so they like to talk and draw by themselves and recommend the so-called "laptop trend" to you. For example, a MM talks to you about their laptop 14-inch large screen, fully modular design, built-in Modem, etc., especially national brands, completely domestic! At first glance,
