Want to buy a laptop, please give me your opinion!

1 shenzhou found the function sufficient when it was the cheapest, but the quality of shenzhou's notebook was the worst. 1 year later, it was time to retire, and there was no desktop.

The quality of IBM is absolutely good, but it is more expensive under the same performance. Quality is the key.

Sony's computers with the same performance are also very expensive, generally not expensive, but Sony's expensive lies in amateurs, very beautiful and exquisite.

Lenovo's computer performance is average, but the after-sales service is absolutely good.

5 Compaq, HP quality is ok, Compaq is mainly for business.

I recommend Toshiba's computer, because mine is Toshiba's, and the quality is absolutely no problem. And now the price has come down, and you can buy a very good one around100000.

Notebooks are cheap at home for a penny, but they are scrapped after 1 year. If you want emergency, buy a better second-hand one, not Shenzhou.

Give you an article on how to buy a notebook and see if it can help you.

Because the internal structure and accessories of notebook computers are opaque (that is, ordinary consumers can't really understand the internal structure and specific models and specifications of notebook computers), and the price is very expensive, consumers are so confused when faced with so many brands and models. I don't know which product to choose and which product is suitable for them without wasting too much money. This requires users to first understand what kind of machine they need and what to do with it, and then analyze their needs by understanding some basic common sense and key points of purchasing a notebook computer, so I believe users can buy a satisfactory notebook computer.

Basic knowledge of notebook computer

Mobile processor:

The processor of a notebook computer is different from that of a desktop computer. Considering the power consumption, it adopts more advanced manufacturing technology and technology, which reduces the power consumption while achieving high performance. Moreover, different mobile processors have their own energy-saving technology (power management technology), which can adjust the frequency or voltage of the processor to reduce power consumption. At present, the mainstream mobile processors are Pentium M, Celeron M, Pentium 4-M, Athlon XP-M and Quanmeida Crusoe, while mobile processors such as Pentium III-M, K6-3 and C3. They are all eliminated products, and users don't have to consider them when choosing.

Pentium m processor has the characteristics of low power consumption and high performance, which is completely designed and developed by Intel for notebook computers, making notebooks have a qualitative leap. However, as a brand-new product, notebooks using this processor are all mid-to high-end products, and the price is relatively expensive. This is a more universal product, so it will be seen in notebooks with various positioning, and it also greatly improves the performance of ultra-thin notebooks.

Celeron M processor is a simplified version of Pentium M processor, which uses the same core as Pentium M and aims at the low-end market. Therefore, the launch of Celeron M has made many mid-to-high-end laptops with Pentium M versions have corresponding cheap models. The Celeron M processor of the same model is generally about 2000 yuan cheaper than Pentium M, and its performance can fully meet the needs of ordinary users. Therefore, students, families and business users who have low performance requirements can consider adopting Celeron M model.

Pentium 4-M processor is a mobile processor improved from desktop processor. Because of its low price and good performance, it still has a market position, and its biggest disadvantage is high power consumption. However, due to its high frequency, the latest version supports hyper-threading technology and still has its performance in multimedia processing, so it is widely used in multimedia notebooks and desktops to replace notebooks. If you want to buy a laptop for home use, Pentium 4-M products are also a good choice. After all, these models are very cost-effective.

Athlon XP-M is a brand-new mobile processor introduced by AMD for Pentium M, which has excellent performance and low price, but its heat and power consumption are still relatively too good to compete with Pentium M. However, due to its low price and good performance, it has been widely used in low-end models above 14 inch. For many students, Velon XP-M notebooks with low price and sufficient quantity are a good choice.

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

Chipset:

Motherboard chipset is also a very important part of notebook computer, which is closely related to 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 in notebook computer chipsets, and others are VIA, but they generally appear in notebook computers using AMD processors. Although these chips exist in the market, their share in actual products is very small, and they often appear in some low-priced notebooks.

It should be noted that some ultra-low-cost notebooks use desktop accessories in terms of chipset, processor and memory. Although the cost is low and cheap, the overall stability is doubtful, and the internal design and heat dissipation are worrying. And there is no-PC card slot, which is an important expansion slot for notebooks. Technically, it's not a laptop. Users should pay attention to this when buying low-priced notebooks.

Memory:

The memory of notebook computer is completely different from that of desktop computer, and the price is much more expensive than that of ordinary desktop computer, but its small size is beneficial to the internal design of notebook computer. At present, DDRAM is widely used in notebook memory, and SDRAM is basically outdated and will only be used when upgrading old computers. Therefore, when we buy a notebook computer, the memory is generally DDRAM specifications, 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 as small as standard SO DIMM memory and very expensive. Notebook memory does not require high speed and pursues stable operation. Therefore, at present, the highest specification notebook memory supported by notebook computers is only DDR333. However, due to the speed limitation of notebook hard disk, notebook computer relies heavily on memory. Proper configuration of large-capacity memory is obviously helpful to improve the overall speed of notebook computers.

Hard disk:

The hard disk of notebook computer can be said to be the slowest developing component in notebook computer. For a long time, there was no qualitative leap in speed. At present, the specification of 4200 rpm is still widely used, and the beginning of 5400 rpm appears in some high-end notebook products. Although 7200 rpm hard disk has been released, due to the mature technology, notebook computers are rarely used 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 reaches 80GB, which is also widely used in notebook computers. However, the 1.8-inch notebook hard disk has a maximum capacity of 40GB and a maximum rotation speed of only 4,200 rpm. It is adopted by some ultra-thin notebook computers (such as Toshiba R 100, Sony X505 and other ultra-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 Radium Dragon 9700 and nVidia Geforce FX Go5650. Although these two graphics cards have strong performance, they also consume a lot of power. They are generally used for mobile multimedia audio-visual center notebook computers or desktop replacement computers, and are of course the best choice for users who play games. In addition, some other discrete graphics cards also have strong 3D performance. Mobile radium dragon 9600, mobile radium dragon 9000, Geforce FX Go5200 and Geforce 4 Go440 are all good mobile display chips, and their performances are arranged as follows: mobile radeon 9600 >:Geforce go 5200 & gt；; Mobile radium dragon 9000 & gtGeforce Go440 & gt Mobile radium dragon, its power consumption is generally inversely proportional to its performance, so it appears in different positioning models.

In addition, there is a force that cannot be ignored in the field of notebook display. They are integrated graphics cards with 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 field of mobile display. At present, the performance ranking of mainstream integrated display chip chipsets is: Intel 855GME chipset >: ATI IGP7000 series integrated chipset >: Intel 855GM chipset >: ATI IGP300 series integrated chipset >: Intel 852MG chipset >: SIS650M & gt Intel 830MG chipset. Intel's latest 855GME chipset integrated display chip, whose performance is equivalent to ATI Mobility Radium 7500, is the best integrated display chip chipset at present. In addition, we should also pay attention to memory. All integrated display chips use main memory as memory. Consider the size of the aggregate memory when using it. If it is too small, it will affect the display performance. If too much main memory is occupied, it will lead to too small main memory and affect the overall performance.

Network equipment:

The network equipment of notebook computer has become the ultimate configuration of notebook computer. Centrino vigorously promoted its "wireless unlimited" (labeled as wireless network card), which was a smash hit. At present, the notebook comes standard with V92 modem and 10/ 100M adaptive Ethernet card, which is the lowest network equipment standard for the notebook. Users must pay attention to whether these two devices are complete when purchasing, otherwise they will be used in the future. In addition, with the popularity of Centrino, standard wireless network card has become a major feature of notebook computers. At present, most high-end notebook computers are equipped with wireless network cards, which can bring great convenience to users. With the laying of wireless network, many public places have covered wireless LAN, which brings great convenience to notebooks with wireless network cards. Of course, the standard wireless network card will raise the price of the whole machine, but for the cost of future upgrade, the standard wireless network card is 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, notebook types can be divided into: 8.9-inch mini-notebook, 10.6-inch ultra-light and thin notebook, 12. 1 4.1inch full-size notebook. So 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 image quality directly affects the mood of notebook users, so an excellent display screen should be paid great attention to by users when purchasing notebook computers.

Key points of purchasing a laptop:

In fact, many friends who bought laptops rushed to buy them on impulse. Before buying, I didn't analyze my own needs, and I didn't fully understand the various characteristics of the notebook computer. I was eager to start, which led to the feeling that the products I bought were not as good as my own ideals, and I regretted my original decision.

Before purchasing a notebook computer rationally, it is necessary to make a full analysis, so as to have a clear understanding of both your own needs and the characteristics of the product. However, many users fail to do this when buying, but listen to advertisements or other people's opinions and unilaterally pursue weight, appearance, brand and so on. In the end, they bought products that were not suitable for them, which made them very upset.

Notebook products, like other things, are not perfect, but the needs of each user are different, and the positioning and functions of each notebook computer are also different. Only when you fully understand your product needs and product characteristics, you will be targeted when purchasing products and buy the machine that suits you best with the most reasonable money.

Ask yourself if you need a notebook.

First, ask yourself what you need a notebook for. If you want to show off, I still advise you to give up the idea at once. Laptop products are updated too quickly. Maybe the notebook you spent 10 thousand yuan on will be eliminated after half a year, and you will regret the price you paid.

If you are completely unfamiliar with computers and only use them at home, it is 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 notebook computer brings convenience and fun 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 own needs

What kind of notebook do you want? What is it mainly used for? As long as you understand these two problems, you will not be aimless and at a loss when choosing products. If you are a business person and travel frequently, 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 what every young person likes, so you can choose some low-end notebooks with strong multimedia functions. This kind of notebook has good performance in all aspects and fashionable appearance, but because students don't need to carry notebooks often, they can have low requirements in weight, so there are more choices for the price of this kind of products; If you choose a notebook for office or home use, a desktop with good comfort and high overall performance is a good choice for you to replace the notebook. Of course, everyone's needs are complex and diverse. Ultra-thin notebooks and multimedia notebooks that emphasize audio-visual functions are both launched for different users. As long as users seriously consider this problem before buying, I believe you will have a general direction in mind, and then it is not difficult to know the characteristics of each product in detail after selecting the scope, and it is not difficult to choose the product that suits you best.

Know your 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 buying a notebook, and don't modify it easily after making a budget.

And this budget had better have two price points, one is your ideal price point, and the other is the highest price point 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 own highest price, and don't trust the recommendation and inducement of the sales staff to lower your standards, so that the products you buy may eventually become a heavy burden for you and pay a high price for unnecessary functions.

Moreover, after determining the purchase mode, it is best to know the price of as many products as possible from various channels, and then ask the buyer after determining a more realistic price. It doesn't hurt to ask a little more, and finally bargain in the most realistic one. The actual transaction price is often 5 ~ 10% lower than the price of the merchant, which depends on your bargaining power. You can sell it if the price is satisfactory. If the price is not satisfactory, don't sell it in a hurry. After all, the price of notebook computers is always falling, and there will always be surprises when you come a few times more.

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 enough, don't blindly pursue the latest technology, the most fashionable appearance, the strongest performance, and don't be too brand-conscious, rationally analyze and choose, so they will definitely choose a product they are satisfied with.

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. To choose a brand with good reputation, fill in the warranty certificate clearly when purchasing, determine the warranty time, and strive for the longest warranty period as far as possible, so that users can use their notebooks without worries.

Buying a notebook is like buying a brand-name machine, and it is easy to walk into the "trap" set by the merchant. Even if you know the online evaluation report by heart, it is hard to resist the lust of local tyrants like plmm, and the small mouth that can tell the dead alive! So 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 "letting a hundred flowers blossom without touching your body"! (whispering: "why do you talk so much nonsense every time!" Kill! " )。 After I resisted countless MM's saliva, I summarized the following misunderstandings in notebook purchase. I want you to pay attention to:

The first misunderstanding: advertising and promotion misunderstanding

This is the easiest misunderstanding to walk into, and it is also the trap that salesgirls are best at. Generally speaking, businesses that are notebook agents and sales are not familiar with the technical trends and electronic fashions in the industry, so they like to talk and draw by themselves and recommend the so-called "notebook computer trends" to you. For example, a MM tells you about their laptop 14-inch large screen, fully modular design, built-in modem, etc. , especially national brands, completely made in China! At first glance, it sounds good, but you won't think so after I analyze it for you.

The first is 14 inch TFT. Don't like 14 inch screen, it's too big! And now many official documents can't use 14 inch notebook, especially MM, it's ridiculous to bring a 14 inch notebook. Secondly, the modular design is easy to use. What is modular design? I'm afraid even the salesgirl can't figure out the specific concept. Modular design was widely adopted as early as the end of 1990s, and it is not a new standard.

General document processing, 6xxx mobile PC is enough to do professional fields such as software engineering and network management, and 20000 is probably just right! To make matters worse, these salespeople like to use such words to cover up the shortcomings of the notebook computer itself and confuse the audience! Third, national brands support domestic products, even more ... Alas, nowadays JS likes to deceive people with the truth!

I just want to ask those MM who sell notebooks, can you find out how many things in domestic notebooks are completely designed and manufactured by yourself? It's not that I don't like domestic products. Lenovo and Founder's notebooks are still very good. I just ask these salesmen to be objective and not to oppress others with facts! And our friends who buy notebooks are most afraid of watching advertisements and are most likely to be deceived. We should carefully study the reports and market recommendations of authoritative evaluation institutions and find out the books that suit us.

The second misunderstanding: misunderstanding of the origin

Some notebooks are produced in different places, but the brand is the same. For example, Toshiba notebooks are generally licensed in China, one is Lenovo Toshiba, and the other is Toshiba notebooks made in the United States. So many salesmen will read these two books together. There are many other OEM brands, such as Taiwan Province Quanta, which you may not have heard of. He is the world's number one notebook manufacturer and also works for some world-famous brands. So although the notebooks you see are the same brand, they are not all original (original factory), just like Sony's color display, which may be from Shanghai Sogo or Miyako, Japan, and the quality is definitely different. So when you buy a notebook, you can't just listen to the salesman (they always like to say that their notebooks are imported and 100% are made in the original factory), so you should carefully check and indicate the place of origin on the logos of many notebooks.

The third misunderstanding: the misunderstanding of after-sales service

In addition, after-sales service is very important! Notebooks are different from our desktops and are expensive, so after-sales service is very important. Whether the manufacturer has set up maintenance stations in various areas or the main use areas purchased by users is an unavoidable misunderstanding for users. No matter what brand, we should consider how the maintenance of notebooks is promised. Don't be confused by PL's mm statement when you buy it. Pay attention to these things, how long is the after-sales service period, what is the specific content of after-sales service, and how long is the maintenance and replacement cycle.

Generally speaking, most notebook products are replaced free of charge 1 year, with limited after-sales service for 3 years. The maintenance and replacement cycle of most products is about 15 days. When purchasing notebooks, it is recommended to choose some imported brands and domestic products with better after-sales service, such as IBM, Lenovo, Founder, Acer, Asus, Toshiba, etc., whose products have better after-sales service. Moreover, IBM has launched the blue express service in this respect, with a national warranty of three years. On the other hand, in China, manufacturers still have a lot to go in terms of maintenance quality and the establishment of maintenance stations.

Nowadays, more and more people buy notebooks, and the profit of single machine of dealers is much smaller than that of a few years ago. Although it is said to be small profits but quick turnover, many salesmen will not be satisfied. Maybe you accidentally got into his way and got a good laptop. Although not everyone can meet JS, you should keep an eye on it and don't get caught. Here, I would like to sum up the most taboo behaviors in the process of notebook purchase, which can not only prevent JS from violating the law, but also manage your money bag in front of a wide variety of notebook computers.

One of the taboos: don't pretend to understand, self-righteous.

Last year, a friend of mine bought a notebook by himself. When he saw a suitable CD-ROM drive, he wanted to buy it, but he thought that the 24-speed CD-ROM drive seemed a little outdated compared with the desktop, so he asked the salesman how much it would cost to change it to a 50-speed one (the notebook doesn't have a 50-speed CD-ROM drive at present). Q: Can people who buy like this not be slaughtered? Before buying a computer, you must make a little knowledge reserve. These days, because the profit of single products is getting lower and lower, people who sell things have been trained. Once you find a rookie, kill him. For example, the salesperson knows that this person who doesn't even know the basic knowledge of notebooks definitely doesn't know to consider those "portable microcomputers" that look like notebooks. They use desktop CPU and motherboard chipset, and the configuration seems a little higher and much cheaper. After listening to the recommendation of the salesperson, I bought it immediately and felt that I made a lot of money. It took me a while to find that my notebook was different from others'. There was no 1394 port or even PCMCIA expansion slot. This is a freak. But you can't buy regret medicine in the world, it's not easy to use, and it's worthless to sell it. What should I do?

What I want to say here is that if users who are not very good at this field need to buy their own notebooks, they can find a knowledgeable friend to accompany them for reference. Of course, it is best to make a little knowledge reserve yourself! Or someone will be grateful for killing you. Of course, we don't want you to become a notebook expert just to buy one! It's always good to know a little, unless you are rich, you can buy a very high-end laptop, regardless of the thousands of dollars or you can buy it in a big-name store.

Taboo 2: unrealistic, follow the trend.

For notebook computers, the trend has just been promoted and there are many advertisements, but this is not necessarily good. Now many friends buy the ultra-low-end Centrino, which may explain this problem to some extent. Some hot domestic brands copied some time ago have produced low-priced Centrino notebooks within 10,000 yuan. By comparison, we can also find that many configurations can only meet the basic operation of Centrino and Windows XP. It can't be said that you can experience the advantages of Centrino, but the battery life is slightly stronger, but the performance may be much worse than the P4 model at the same price.

The key is to look at your needs. If you especially like new experience technology, you need your pocket support. Don't buy the cheapest new product. The ultra-low-priced Centrino may not be as expensive as the P3 notebook. In this era when there is only wrong buying and no wrong selling, we must grasp the principle of "enough is enough". There are many good things, and the trend will never catch up.

First of all, make clear what you are buying a laptop for, what are the requirements for machine performance, mobility and battery life, and then expand the basic requirements a little, which is basically the machine you are more suitable for.

Taboo 3: bargain at will.

Many people buy too much in the free market and get used to the shopping theory of "20% discount". Buying a notebook is a desperate counter-offer, and it is certainly good and possible to pay a little price. After all, making money is not that easy. Give less, you can spend more. But, you know, buying a laptop is not buying food. Before 2000, selling a mid-to high-end laptop really earned thousands of dollars. Not now. Only high-end brands such as IBM and Sony have high profits. Generally speaking, the profits of foreign first-line brands such as Toshiba, NEC and Sharp are also considerable, and the profits of most domestic notebooks are not very high (of course, much higher than those of computer cities selling desktops).

Now that I mention it, you may not know exactly what kind of notebook can be repaid below the quoted price, because there is no uniform standard for this thing. It can only be said that "it is not a loss to shop around". Go more, ask more and see more. Of course, this should be compared with the same brand, model and configuration. If your time is precious, find a reputable dealer. Bargaining at will only let others know that you are not good at it, and it is a waste of time. In the end, the business stopped and nothing was bought.

Taboo 4: Superstitious evaluation

Now all media have their own evaluation departments, which specialize in third-party evaluation of some products, and then announce the evaluation results to the public through various channels. Now many friends are looking for relevant comments when they buy digital products. This is very good, so that you can fully understand the detailed information of the machine. In addition, you still need to consider it clearly when choosing, and you can't blindly trust the evaluation.

The evaluation results only suggest that the media provide users with a wide variety of products when purchasing. You can't let the evaluation completely dominate your thinking, so we consumers should never see an evaluation saying that this notebook is good and choose this one immediately. Everyone has different needs for machines. Only by integrating all aspects according to your own needs can you really choose the most satisfactory product.

Taboo 5: superstitious advertising

We won't elaborate on this point, and the ultimate goal is only one, so that you can pay for it and seize "our products are good" and "buying our products is affordable" to encourage consumers to buy. Borrowing an old saying, "Don't believe it all, don't believe it all", between believing and not believing, you need to verify it yourself, and also pay attention to whether the selling point of the advertisement is what you need.

Taboo 6: blindly follow big-name manufacturers

Even big manufacturers have low-end products, most of which are not the equipment and quality advertised by big manufacturers, but the prices of these low-end products are often equivalent to those of mainstream products in the market, so don't be obsessed with big brands and choose products that suit you from reality.

Taboo 7: Buy products from informal channels.

At present, parallel imports of notebook computers on the market are not smuggled products in the traditional sense, but also counterfeit and shoddy products and refurbished products. Some manufacturers don't enter the market through formal channels for China products, which may make some consumers think that there is not much difference between parallel imports and formal products. But in fact, the harm brought by parallel imports is very great.

First of all, the operating environment of parallel imports is not suitable for domestic users in many places. Some parallel laptops don't have Chinese operating systems or use pirated Chinese operating systems, and the compatibility and stability tests before leaving the factory are not aimed at the Chinese environment. There is also a keyboard that is not in line with China people's habits. For example, the layout of Japanese keyboards is different from ours, so it is difficult to operate. I am not used to using Chinese environment after I am familiar with it.

Secondly, parallel imports cannot enjoy genuine system recovery and specialized software use and upgrade services.

Thirdly, most parallel imports enjoy normal after-sales service, not to mention international joint guarantee. Most parallel dealers are not fixed and cannot provide spare parts for replacement. However, it may cost more to enjoy after-sales service through formal channels, and they will not be treated fairly.

Finally, we need to consider whether parallel imports are really cheap and can save costs for notebooks. You need to consider the extra cost of purchasing genuine software, after-sales service and so on. Therefore, in the process of purchasing a machine, don't see that it seems cheaper to buy parallel notebooks around you, just follow the crowd and buy notebooks through informal channels. Now there are many assembled and refurbished notebooks, and Japan has a professional IBM notebook renovation factory, which flows to various countries through informal channels after renovation.

Taboo # 8: Check the test specifications carefully without unpacking.
