2 ibm's quality is absolutely good, but the same performance under the more expensive, expensive in the quality of the
3 Sony's computers of the same performance is also very expensive, cut is not the general expensive, but Sony's expensive in the amateur on the
4 Lenovo computer performance is generally good, but the service is very good, it is very good.
4 Lenovo computer performance in general, but the after-sales service is absolutely good.
5 Compaq, HP quality can be, Compaq to business-oriented
6 Toshiba's computer I recommend, because my is Toshiba, the quality of absolutely no problem. And now the price has come down, about 10,000 can buy a very good and very good.
Laptops are worth every penny, and Toshiba is cheap, but after 1 year of use, it's a write-off.
Give you an article on how to buy a laptop and see if it helps you
Laptop computers are not transparent due to their internal structure and accessories (i.e., the average consumer doesn't have a true understanding of the internal structure of the laptop as well as the specific models and specifications of the accessories), and they are also very expensive, so consumers are faced with so many different brands and models of laptops. Consumers face so many brands and models, and the price difference is also so different in the case of very confused, do not know what they choose which product is good, which product is suitable for them and do not need to waste too much money. This requires the user to first understand what kind of machine they need, what they use to do, and then through the understanding of some of the basic knowledge of the laptop and the purchase of points, so that the analysis of their own needs, I believe that the user will be able to buy a laptop to their liking.
Basic knowledge of laptop computers
Mobile processor:
The processor of a laptop computer is different from the processor of a desktop computer, which takes into account the power consumption and therefore adopts a more advanced manufacturing process and technology in order to achieve high performance at the same time as to reduce power consumption as much as possible. And different mobile processors have their own energy-saving technology (power management technology) can be adjusted with the processor's operating conditions of the processor frequency or voltage to reduce the operating power consumption. Currently the mainstream mobile processors - Pentium M, Celeron M, Pentium 4-M, Athlon XP-M, and Ameda Crusoe, while the Pentium III-M, K6-3, C3 and other mobile processors have been belonging to a long time out of fashion products, users can not need to consider when choosing. The choice is a no-brainer.
Pentium M processor with low power consumption, high performance characteristics, is Intel completely for the notebook computer design and development, so that the notebook a qualitative leap, but as a brand new product, so the use of this processor laptop are mid-range and high-end products, the price is more expensive, this is a more all-round product, so a variety of positioning of the laptop will be seen in its
Celeron is the first laptop in the world to use this processor.
The Celeron M processor is a simplified version of the Pentium M processor, with the same core as the Pentium M, and is aimed at the low to mid-range market. Therefore, the Celeron M listing, so that many of the original Pentium M version of the high-end laptop also has a corresponding cheap model, the same model using the Celeron M processor products than Pentium M products generally cheaper than about 2,000 yuan, and its performance is also fully able to meet the needs of the general user, so students, families, commercial users of the performance of the The Celeron M processor is the most powerful and efficient way to maximize the performance of your PC, and it can be used in a wide range of applications.
The Pentium 4-M processor is a mobile processor improved from a desktop processor, and because of its lower price and better performance, it has always had its market position, and its biggest drawback is its higher power consumption. But because of the high frequency, and the latest version also supports Hyper-Threading technology, so in multimedia processing and its performance, so it is still widely used in multimedia notebooks, desktops instead of type of notebook, if you are completely to buy a laptop to use in the family, the use of Pentium 4-M products is also a good choice, after all, the current part of the The price/performance ratio for all models is very high.
Athlon XP-M is a new mobile processor launched by AMD for Pentium M. It has excellent performance and is inexpensive, but comparatively speaking, the heat and power consumption are still good enough not to be able to compete with Pentium M. However, due to the inexpensive price and good performance, it has been adopted in a lot of low and medium-end 14-inch or more models. Athlon XP-M laptops are a good choice for students who want a cheaper, more plentiful notebook.
Allmida's Crusoe is an ultra-low-power mobile processor, such as the use of software to simulate the hardware processing algorithms, and therefore greatly reduces the number of transistors, so that the power consumption control is very low, but accordingly, the performance is not high, but it is used in many mini-notebook computers, such as notebooks have 5.6-inch, 8.9-inch, which is not a requirement for performance. It is not a product that requires performance, super portable is its pursuit, so he also has its part of the market. In addition, the latest Efficeon processor from Allmart will be released soon, and we expect this ultra-low-power mobile processor to improve on its performance.
Chipset:
The motherboard chipset is also a very important component with the laptop, both in terms of performance and overall power control, and the chipset is closely related. In the laptop computer on the best overall performance of non-Intel mobile chipset, whether it is memory, disk performance, or power management are the most outstanding, other competitors in this field can not compete, which is Intel in the notebook field is far ahead of one of the reasons. In addition, in the laptop chipset common SiS, Ali and Ati North Bridge + Ali South Bridge, others have VIA, but generally appear in the use of AMD processors in the laptop, these chips, although the presence of the market, but in the actual product occupancy rate of few and far between, often in some of the low-priced laptop.
It is important to note that some ultra-low-cost laptops use desktop components in the chipset, processor and memory, although this is a low-cost, inexpensive, but the overall stability of the doubtful, and the internal design as well as thermal aspects of the concern, and there is no laptop is very important to the expansion of the slot - PC card Slot, from the strict sense can not be considered a laptop, users should pay attention to this point when buying low-priced laptops.
Memory:
Laptop memory is also a completely different specification and desktop memory, the price is much more expensive than the general desktop memory, but the volume is small, in favor of the internal design of the laptop. The current laptop memory is also commonly used DDRAM, SDRAM is basically obsolete, only the old type of computer upgrades will be used, so we buy laptop memory are generally DDRAM specifications, one for the more common SO DIMM laptop memory; one for the Micro-Dimm memory. Micro-Dimm memory is generally used in ultra-thin and lightweight notebook. Micro-Dimm memory is generally used in ultra-thin and lightweight laptops, and is half the size of standard SO DIMM memory and very expensive. Notebook memory on the speed requirements are not high, it pursues the stable operation, so the current laptop support for the highest specification of notebook memory is only up to DDR333, but due to the limitations of the notebook hard disk speed, the laptop's dependence on the memory is very large, appropriate configuration of high-capacity memory to enhance the overall speed of the notebook will have a very obvious help.
Hard disk:
Laptop hard disk can be said to be the slowest development of laptop components, long-term speed has not been a qualitative leap, the current widespread or 4200 rpm specifications, 5400 rpm began to appear in some high-end models of laptop products, 7200 rpm laptop hard disk, although it has been released, but due to the consideration of the technical maturity, there are still very few notebook computers used. The size of the current notebook hard disk is divided into 2.5-inch and 1.8-inch two kinds, 2.5-inch notebook hard disk has reached a maximum capacity of 80GB, but also usually commonly used in notebook computers; and 1.8-inch notebook hard disk maximum capacity of 40GB, the highest speed is only 4200 rpm, by some of the limit of thin and light notebooks used (for example: TOSHIBA R100, Sony X505, and other extremely thin and light products), expensive and difficult to upgrade.
Mobile display chips:
With laptops becoming more and more powerful, gaming has also become an entertainment function of laptops. The field of mobile graphics cards is still the world of ATi, although the rising star nVidia to catch up, but in the overall power consumption and performance to be slightly behind ATi. currently the strongest mobile graphics card when the ATI Mobility Radeon 9700 and nVidia Geforce FX Go5650, the two graphics cards, although strong performance, but also power consumption are not small. These two graphics cards are powerful, but also consume a lot of power, and are generally used in mobile multimedia video center type of laptop or desktop instead of type of computer, which is of course the best choice for users who play games. In addition, there are other independent graphics cards also have strong 3D performance, Mobility Radeon 9600, Mobility Radeon 9000, Geforce FX Go5200, Geforce 4 Go440 are good mobile display chip, its performance ranking: Mobility Radeon 9600> ;Geforce Go5200> Mobility Radeon 9000> Geforce Go440> Mobility Radeon, whose power consumption is generally inversely proportional to their performance, so they all appear in differently positioned models.
In addition, there is a force to be reckoned with in the notebook display field, and they are the integrated graphics cards, which consume the least amount of power and have a good 2D display, so they are commonly found in business notebooks and thin-and-light notebooks, and they can even be said to be the absolute mainstay of the mobile display field. Currently the mainstream integrated display chip chipset performance ranking: Intel 855GME chipset & gt; ATI IGP7000 series integrated chipset & gt; Intel 855GM chipset & gt; ATI IGP300 series integrated chipset & gt; Intel 852MG chipset & gt; SIS650M & gt; Intel 830MG chipset. Intel's newly released 855GME chipset integrated display chip, performance equivalent to ATI Mobility Radeon 7500 level, is currently the most outstanding integrated display chip chipset. In addition to pay attention to the video memory, the integrated display chip are through the *** enjoy the main memory as the video memory work, in the use of the use of the video memory to consider the size of the set, too small to affect the display performance, too large to occupy the main memory leads to the main memory is too small to affect the overall performance.
Network equipment:
Laptop network equipment has become the ultimate laptop to a configuration, Centrino is vigorously advertised its "wireless unlimited" (labeled by the wireless card), and the red hot, the current laptop comes standard with V92 modem and 10/100M adaptive Ethernet card, which is the current notebook standard with V92 modem and 10/100M adaptive Ethernet card, which is the current notebook. Adaptive Ethernet card, which is currently the minimum requirements of the notebook network equipment standards, users must pay attention to the purchase of these two devices are complete, otherwise the future use may bring a lot of inconvenience. In addition, with the popularity of Centrino, the standard wireless card has become a feature of the laptop, most of the current high-end laptops are configured with a wireless card, which gives the user can bring a great deal of convenience, with the laying of the wireless network, a lot of public **** occasions are covered by a wireless LAN, which has a wireless card with a laptop with a huge convenience, of course, the standard wireless card will bring the machine The price of the standard wireless card will bring an increase, but for the cost of future upgrades, the standard wireless card is still more cost-effective.
Display:
The display of the laptop can be said to be one of the most important components, the size of the display directly affects the size of the laptop volume, the current type of laptop can be divided into: 8.9-inch mini-notebook, 10.6-inch ultra-thin and lightweight laptop, 12.1-inch thin and light laptop, 14.1-inch full-size type of laptop, 15-inch and 17-inch desktop replacement type laptops. Therefore, the size of the screen is also an important factor for users to buy a laptop, depending on what type of laptop you need. The display is also a laptop's power consumption, its power consumption also determines the use of the laptop time, and the quality of its screen directly affect the mood of the laptop user, so an excellent display is the user to buy a laptop to pay close attention to.
Laptop purchase points:
In fact, many of the friends who buy laptops are impulsive when they rush to buy, before buying and not to analyze their own needs, but also do not go to a full understanding of the various characteristics of the laptop computer in a hurry to get started, resulting in a later feeling that they are not as good as their ideal purchase of products, regret the first time! The first time I saw this, it was a very good idea to get the best out of it.
Rationally, before buying a laptop is to do a full analysis, both of their own needs and the characteristics of the product to a clear understanding, and many users do not do this when buying, but listen to advertisements or other people's words, one-sided pursuit of the weight of the model, the appearance of the brand, etc., and finally buy the product is not suitable for their own, and make a lot of trouble.
And laptop products and other things, there is no perfect, but each user's needs are different, and each laptop positioning, functionality is not the same, only a full understanding of their own needs and product features, the purchase of products will be targeted, with the most reasonable money to buy the most suitable for their own machines.
Ask yourself if you need a laptop or not
First, ask yourself what you want a laptop for. If you are to show off, then still advise you to immediately dispel this idea, laptop products are updated too fast elimination, maybe you you tens of thousands of dollars to buy a laptop in six months has been reduced to the object of elimination, and that's what you will be for you for you to pay tens of thousands of dollars and regret.
If you are not familiar with computers at all, and only at home, the choice of laptop is not bad, but you have to think about it, with half the price of a laptop can buy a desktop in all aspects of outstanding performance, and later upgraded also more convenient, so we think your first choice should be a desktop.
So what kind of person is a good candidate for a laptop? Of course, if the laptop brings convenience and enjoyment to your work, study and life, then you can choose him without hesitation. For example: frequent business travelers, school students, programmers and a second computer in the family.
Understanding your needs
What kind of laptop do you really want? What is it primarily used for? You just have to figure out these two questions, and you won't be aimless and confused when you shop for a product. If you are a businessman, often on the go, then a stable and thin business notebook will be your best choice; if you are a student, you may pay more attention to the price, but fashionable style is loved by every young people, so you can choose some of the multimedia features oriented to the middle and low end of the notebook, these books in all aspects of the performance of the good, the appearance of the more fashionable, but due to the Students do not often need to carry a notebook, so the weight can be less demanding, the price of such products have more choices; if you choose is an office or family notebook, with good comfort and overall performance of the desktop instead of the type of notebook is a good choice for you. Of course, everyone's needs are complex and diverse, ultra-thin notebooks, multimedia notebooks emphasizing audio and video features are launched for different users, as long as the user carefully consider the issue before buying, I believe you will have a general direction in mind, and then in the selected range of specific understanding of the characteristics of each product, to pick out the most suitable for their own products will not be a difficult task.
Clear their budget
Laptop prices vary greatly, even if the same positioning, configuration is basically the same product, because of the different brands will have a different price phenomenon, therefore, shopping for a laptop before the budget is also very important, and do not easily modify the budget.
And this budget should ideally have two price points, one is your ideal price, and the other is the highest price you are willing (and able) to afford. When you're actually shopping, use the ideal price first, and only consider the maximum price if you find a model that really suits you but is more expensive, but don't exceed your maximum price by any means, and don't be gullible enough to let go of the scale by trusting the salesperson's recommendations and inducements, so that you end up purchasing a product that may become a heavy burden on you, paying a high price for features that you don't need.
And after determining the purchase of models, it is best to learn from various channels as much as possible the price of the product, to determine a more realistic price and then go to buy the business to ask, ask a few more will not lose, and finally in the most real one bargaining, the actual price of the deal will often be less than the price of the business of 5 to 10%, it depends on your bargaining power. If the price is satisfied with the shot, if the price is not satisfied with the shot, do not rush out, after all, the price of laptop computers is always down, more trips there will always be a surprise.
Summary:
Laptop is a diversified product, so the user must be clear before buying their own purchase intentions, adhere to the principle of good enough, not just the pursuit of the latest technology, the most fashionable modeling, the most powerful performance, as well as do not be too heavy brand awareness, a reasonable analysis, rational choice, so that you will certainly choose to a product that makes you satisfied.
In addition, due to the current domestic notebook market is not mature, notebook computer after-sales service is a headache. Therefore, before the purchase should pay attention to this issue, and take it as an important factor in the purchase of machines, choose a reputable brand, fill in the purchase of a clear warranty voucher, to determine the warranty time, where possible, try to get the longest warranty period, so that users can use the laptop to be free of worries
Purchase of the book as buying a brand-name machine, it is easy to walk into the merchant to set up the "trap". "The first time I saw this, it was a very good idea. Even if you memorize the online reviews, it's hard to resist the winks of a plmm store and the mouth of a dead man! Therefore, in addition to knowing the technical parameters and indicators of the product you want to buy, you also need to practice "through the flowers, leaves do not touch the body" of the highest state! (Little trumpet language: "Why do you every time so much nonsense! Kill!) The most important thing is that you have to be able to get to the bottom of the problem. The first is that it is easy to get into the misunderstanding, but it is also the best way to get into the trap of the sales lady. Generally speaking, the notebook agent and marketing business, for the industry technology trends and electronic fashion lack of sufficient understanding, so they like to talk about their own drawings, to recommend to you the so-called "Ben Ben trend". For example, a MM to talk to you about their side of the notebook 14-inch large screen, fully modular design, built-in Modem, etc., especially the national brand, completely national products! At first glance, it sounds very good, to be even after you analyze, you will not think so.
First of all, 14-inch TFT, I am not like 14-inch screen, but also too big! And now a lot of briefcases can not fit 14-inch laptop, especially MM, with a 14-inch laptop is a very ridiculous thing. Secondly, modular design and good enough to use. What do you mean by modular design? I'm afraid that even the sales lady herself couldn't figure out the exact concept, and modular design was widely adopted back in the late 1990s, not a new standard.
General document processing, 6xxx mobile PC is good enough to use, to do software engineering and network management and other professional areas, I am afraid that the 20000 is just right! What's even more annoying is that these salesmen like to use such verbiage to cover up the lack of design of the laptop itself and confuse the public! Once again, the national brand, support for national products, but also ......! Alas, nowadays, JS likes to use the axiom to deceive!
I would like to ask those who do this book sales MM, you can figure out the domestic notebook inside a few things are completely their own design and manufacture? I don't dislike Chinese products, Lenovo, Founder's notebook is still very good, just please these salesmen can be objective, don't use the theory to pressure people! And we buy laptops friends, the most taboo look at the ads to buy, which is the most likely to be deceived, should seriously study the authoritative evaluation of the agency's report and market recommendations, to find out what is suitable for their own this book.
Second mistake: origin mistake
Some notebooks have different origins, but the brand is the same. For example, Toshiba notebooks, generally in the domestic licensed goods there are two kinds, one is Lenovo Toshiba, a U.S.-made Toshiba notebooks. Therefore, many salesmen will mix these two kinds of notebooks together. Some other brands, they have a lot of OEM manufacturers, such as Taiwan Quanta, you may not have heard of, he is the world's first notebook manufacturer, but also for the world's some famous brand OEM production. So we see the book, although the same brand, but not necessarily all original (original manufacturer), like SONY color display, may be Shanghai Suo wide, there may be a Japanese Ichimiya original manufacturer, the quality is certainly different. Therefore, we buy this book, not just listen to the salesman's words (they always like to say that their books are original imports, 100% original manufacturing), to double-check, in many of the book's logo will indicate the place of origin.
The third mistake: after-sales service misunderstanding
In addition, after-sales service is very important! This book is not the same as our desktop, belong to a very delicate things, so after-sales service is very important. Whether the manufacturer in the regions or the user to buy the main use of the region set up a repair station is the user can not avoid the misunderstanding. Regardless of the brand, it is important to consider how committed its repairs are in terms of laptops. You are buying, do not be confused by the PL's mm rhetoric, pay attention to ask these things, after-sales service period is how long, after-sales service is the specific content of what is the repair and replacement cycle is generally how long.
Generally speaking, notebook products are mostly based on 1 year free replacement parts, 3 years of limited after-sales service, most of the product repair and replacement cycle in about 15 days. When choosing a notebook is recommended to choose a better after-sales service of some imported brands and domestic products, such as IBM, Lenovo, Founder, Acer, Asus, Toshiba's products to implement the after-sales service are very good. And IBM in this regard launched the Blue Express service, the national 3-year warranty, and look at the domestic, in the quality of maintenance and repair stations set up by various manufacturers there are still a lot of road to go.
