After a summer of baptism, a group began to prepare our students back pack, far from his home and began reading his new career. Commodity reserves in the new semester, the notebook will naturally appear in people's shopping list. After all, in today's university life, the laptop has become a necessity for everyone, whether learning or entertainment, gave their lives bring great convenience, but how to choose a suitable laptop is indeed a knowledge. Especially in the cohabitation of these stores in Zhongguancun, how to choose a value for money computer, each person should learn. Today I introduce to you some of the purchase when you buy this experience, I hope to give us some help, do not fight a battle unprepared.
Steps / methods
To win public long
Before buying this, we should first take a look at the more popular online which machine, which machine a good reputation, cost-effective, so that the overall state of the current market there is an understanding, because digital products is the speed with the new generation is quite fast, you may have bought a laptop a friend, but he was bought by the purchase of the Best Laptops when it is only when the more popular machines, the present-may have already become obsolete Moreover, non-professionals not been concerned about the laptop market, they still go online to look better in person. In addition to the various forums you can look up how netizens evaluation, so that you can be aware of.
Identified uses
Of course, this would make the best buy they use, to make their own book to play out his greatest feature. If we just check the internet, web browsing and learning, then it is not the pursuit of high configuration, to say look at today's notebook market, almost any laptop can do that. So this time we do not have to be too harsh on the machine configuration, the machine will focus on appearance, workmanship, prices in these areas. But if you are a game or film enthusiast, this time we must carefully weigh the machine configured.
Processors, graphics cards, hard drives need to be considered. Compared with the performance of the processor, graphics performance is good or bad, but for a 3D game is critical, the processor can be a little time, but the graphics must be adequate. Also should consider the course of storage, now a game, or a high-definition movies, small is 5,6 G, a dozen large G, the hard disk is too small too stretched. Although the HDD is very cheap, but who do not want to always be dragging around a hard run!. Besides the processor, it seems that many people on this importance, it is not. The machine is not entirely dependent on processor speed. Of course, naturally, the better the processor the better, but most of them this is not very different applications. But if you will engage in graphic design or video editing, the processor's performance is naturally essential. We who do not want to finish a video, export to light for several hours slower than the others.
Configuration options
After we determine the end use, to determine the election on how the machine configuration. The first is the CPU, it seems we love to use their cores to measure CPU performance, if certain than single-core dual-core poor, the three core must be better than dual-core is strong, this is actually one of our misunderstanding. Such as store shopping guide now like to say that the equivalent of two dual-core CPU, the equivalent of three triple-core CPU, but, in fact, dual-core processor performance is far from like elementary school math as 1 +1 = 2 level.
There are three main reasons:
First, a performance full advantage of the hardware dependent software, very big. The current mainstream Windows multi-tasking multi-threaded operation, can provide good support for multi-core CPU; but in the application software, especially games software, is still mostly single-threaded or dual-threaded. Although the two processor manufacturers to advocate, in Microsoft's strong encouragement, many of the latest release of software has a multi-threaded version. But within a year or so, the advantages of multi-core CPU, or because of the lack of multi-threaded software can not be fully reflected.
Second, the need for heat control, the two major processor manufacturers in production of multi-core processors have reduced the frequency, resulting in greatly reduced in performance. Again, PC's whole system is an organic whole, follows the "bucket theory", which part of a "short board" will result in overall lower performance. At present, the bottleneck is definitely not the individual PC CPU frequency is currently the number size. Thus, the mere pursuit of multi-core CPU does not make the user experience significantly faster.
In short, multi-core CPU but in multitasking, multithreaded environment, only some performance advantage; and 3D games such as traditional single-threaded program, and some multi-core CPU is far better than the actual performance of the top high-frequency single-core CPU. We should also understand that the so-called good is built on the same multi-core architecture and frequency, may be multi-core CPU in the multi-tasking and multi-threading performance is more outstanding, but it should also measure the frequency of secondary cache and the manufacturing process, These are the core of how many can not decide the merits of the performance of a notebook. It is also often used by dealers, regardless of the actual use of our consumers, blindly recommended multi-core products and eventually buy only inviting overkill jokes.
Then look for the CPU card, the card is equipped with only the book is mainly NVdia and ATI, simply, N card's strengths is the games, while the A card's strengths is the high-definition, the user can use according to their needs Which video card to determine the purchase. Memory in DDR2 and DDR3 is divided into two categories, compared to DDR2 for less power consumption and heat, higher operating frequency, and the mainstream models are now of DDR3 memory. In addition to differences in capacity hard disk, the speed is also a very important aspect is the impact of disk speed and cache performance of the two main aspects of 7200 compared to 5400 has a faster read and write. But the 7200 power-hungry, only high-end machine is equipped with most or 5400 rpm hard drive.
Field reconnaissance
At this time I believe users should have a favorite laptop, this time the store is going to meet a real machine, thoroughly, and see if there are no recent promotional activities. In conversation with the business, it would be for the price of the machine and its specific appearance with an intuitive understanding, of course, JS does not rule out some false low, illegal means to win over customers, then we should shop around, should not blind arbitrary.
Model Secret
To buy this, be sure to remember to buy their own specific model of the machine. Because the laptop manufacturers usually produce a range of products, because both belong to a family, so usually use the same mold, but the configuration is different. If you do not remember the specific model, it is easy to be with the machine when the business to low-sell high with the machine, so that consumers complained again and again.
The temptation gifts
When we buy a notebook computer, very much like to some of the gifts, in fact, the salesman in the gifts of time, only one principle: the cheapest, so basically all spam sent. Therefore, the most intelligent consumer, will be first thing, then talk to the salesman, I do not want these things, you give me less money, do not expect to lose the fat salesman tell you the worth, the worth the extent of, basically, he said the value of $ 100 thing, the cost of 30 yuan on the good. can reduce how much depends on how you talk about friends with the salesman.
Testing machine steps
Other consumers and businesses negotiated prices, will begin the process of testing machine, and this time, mainly not the first payment, be sure to complete such testing machine after the payment, after the machine is used, first check the packaging is There are signs of re-packaging, above and below the seal must be checked to see if there are opened or re-package traces, once helped a friend buy the JS open the packaging from the bottom in front of us, is to deceive the public sale again . Laptop bags are generally friable head attached, in Kaifeng attention for damage. See warranty card and serial number of the fuselage is has been. Check the LCD screen, when we buy the books did not pre-installed system, this time you can choose to enter the black screen blue screen of BIOS and DOS to see, much of the installed system saving time, first install the boot CPU INTEL special detection software, view the CPU chastity arch, see if it is perpetrating a fraud by JS into non-retail version of CPU, this situation has occurred repeatedly.
Service
After buying this, each laptop brand service policy is different, so that we should buy this before should know. On the invoice, I would suggest is to, although the warranty, then the invoice can not guarantee. Note, however, there are still differences. If there is no invoice, the warranty date is calculated by the date of manufacture, invoices, invoice date is calculated by the warranty date. In addition, the invoice is to safeguard their legitimate rights and interests of the legal basis is not in receipt of certain aspects of legal effect, since we have thousands of dollars to buy a book, then why care about a hundred dollars, or to the invoice good.
I believe after reading these, readers and friends about the addition of a few hand-selected machine ready, here, I hope everyone liking the cake and friends can buy their favorite book!
