First, out of the box - show me how to determine the JS is not a new machine?
Many users to buy books when friends do not like split-off closure of the machine, mainly because people were concerned encountered rework machine dealer or feet, the replacement of parts too. But in fact, there is no split-off closure of the books will always be, for example, only a few days before the prototype, for example, has just opened to other users read the goods and so on, it does not mean that these machines have problems, it is entirely possible rest assured that the purchase of machinery. And those letters have to be properly installed inside the box of books does not necessarily there is no break, because a hairdryer on the books can be completely solved packaging seals, leaving little trace. Therefore, the time to buy books, buy a new machine, but this does not mean that there is no good seals also stuck on the books is the new machine, does not mean that the demolition had boxes of books will not be able to purchase. The key is to look at books is not a new machine. Below and tell you that a number of identification books is not a new machine tips:

1, see serial number. Most of the notebook and battery on the fuselage should be affixed with its serial number of the same, if the battery serial number and serial number of the host inconsistent, books most likely had been replaced battery; In addition, in the procurement of foreign brands laptop products whether the serial number of the fuselage and battery and package on the line to test whether the product of parallel imports based on a very important, it is necessary to know the parallel foreign notebook can not be at home to enjoy the quality. 2, see anti-theft keyhole. If there is imprinted on Play-off anti-theft lock notebook, it is highly possible prototype is done;
3, see the end of the foot. If there are worn and dirty, that was used, the production line is not so dirty table; 4, look at the fan. If the fan has a thin layer of dust on the use of reach for more than a week; 5, see the production date. Three months ago, the factory's books still sell the market, it is necessary to pay attention to the. Electronic product sales update extremely fast, it is impossible to make a book for such a long time pressure in the channel's.

6, look at the keyboard. New books of the keyboard is very clean, but not shiny. Gap keyboard used books will be dust, commonly used in several key sub-will be illuminated; 7, see the screw. This is not to say now? Screws have been removed? That or make a U-turn on the go! 8, to see the cracks. Be processed before the renovation books, the gap is generally difficult to deal with such as new, such as books AB screen surface of the small gap between, for example, drive the gap, and even MODEM and PCMCIA card inside these interfaces, if we can find a deposition , you can be sure As was put off prototype, but not sealed. What? Also found books rub resin used in cotton yarn? It also again I asked how to do it? In short, look at books is not a new machine, it can not be outside the box was opened to generalize. Opened may not necessarily not a good book, on the contrary, the prototype are generally the most reliable books. However, the packaging of books in good condition, it is necessary to identify more carefully. When the selection of the most important thing is to listen carefully. Second, Dead - count the number of multi-ah?
Dead screen a good tool for detection-NOKIA Ntest LCD screens, notebook buy the most headache is Dead, after all, who are unwilling to buy their new notebook will have several major bright spot, right? But almost no manufacturers of commitment is not Dead. ASUS notebook vendors only promise no bright spots, but we can go look at the ASUS forum, it is just word games, worse than the dark spots, but also can not stand ah! And they point to have a color known as the color point is not bright spot can not be security, so now the standard by, highlight what is really hard to say the.
LCD problems of the Dead LCD industry has a long history, due to the reasons for its own manufacturing technology, LCD of the Dead it is difficult to avoid, but the number of Dead is normal for them. LCD is currently manufacturing sector has not given a say in the end the number of Dead is normal, in fact, the emergence of Dead is a single crystal liquid crystal display body is not working properly, there may be red, blue, green different defect. Dead are rooted in the emergence of production, if the issue of transit or use a long time appeared to answer is prevarication. Dead in the LCD screen because the crystal composition has doomed the moment, but some time in the factory does not appear, or some of the problem is not serious, and only in use for some time after the step by step into a dark point (light dark) . In other words, the Dead have acquired a very small possibility. Therefore, there is Dead to buy the books, but also will not have to worry about the proliferation of Dead. LCD screen for the Dead, which is but a helpless topic, in general, the purchase of books, the LCD screen than three Dead, in particular the existence of Dead Zone A, then you can refuse to buy. Time in the selection of books, where we can bring some of the proposed screen test software on the screen to conduct a detailed test, be sure to please everyone before buying carefully selected so as not to cause unnecessary in the future trouble. Third, fans - it's not in the end of the transfer? Notebook cooling tools - fan
Notebook and desktop fans not the same as the notebook is affected by temperature control (some individual desktop except notebook CPU). In other words, the higher the temperature, fans will be running faster, lower temperature fan will not even work deceleration. First, the benefits of such power, and second, lowering the noise, the three can be extended fan life. Generally speaking, the notebook fan speed can be set up in COMS by adjusting power-saving mode to adjust. Some notebook COMS configuration than the whole, can be directly set temperature and fan speed. Some friends suspect notebook fan noise, with a total want fans to stop working, the fans start low temperature adjusted, it may lead to overheating CPU and system temperature, resulting in death and reduce life-related accessories, is unhelpful Therefore, notebook fan, frequent turn bad, do not work also unfavorable to the master of a degree.

General experience is that at room temperature 20 degrees Celsius, when a well-ventilated room, Internet browsing, Centrino notebook CPU fan, it should be in every 20-30 minutes to start time, the work of about five minutes to stop the work of energy conservation. When playing a game, about ten minutes to start one. If normal operation has been crazy, then you should be testing is not set or control circuit COMS problem. Fourth, the keyboard - what is the feeling? Logo with Chinese notebook keyboard

Many of my friends and some of the media room evaluation tests, it will say so and so notebook keyboard feel how, in fact, this is the most difficult to measure the sentence. Notebook keyboard keys way than in an ordinary desktop keyboard short a lot, in itself, is very uncomfortable. So do not feel too good. And the keyboard keys for each person the flexibility of hardware and software, is also not the same preferences, so the use of its own feelings that handle how the keyboard is not objective.
A good notebook keyboard, to do:
1, adequate space, following the general 12-inch notebook, the keyboard is often used tight design, the distance between the keys close to playing characters very uncomfortable.
2, keys in prison, some bad notebook keyboard keys, according to an angle when another tilt angle even years, playing such characters, the keys staggered, it is very difficult subject.
3, the overall level, thin notebook keyboard, often following the installation of a notebook memory, hard drives and other accessories, some of the bottom of the notebook keyboard design is not structured in some places there are accessories, some places are empty, in addition to the keyboard itself, steel-lined thin, typing, when the bottom where there will be no accessories subsidence feeling, not only uncomfortable, and may even feel that by fall, according to a broken sense of horror. From the perspective of lower head-up the past, and even can see the keyboard is a wave-shaped, very smooth. Such a keyboard even more terrifying is that books when temperatures are high, will muster the keyboard up slightly, but closed after shutdown screen, keyboard muster has not returned in situ, but friction LCD screen, resulting in LCD printed on the screen and keyboard layout as abrasions, beyond repair, would affect the warranty. As very serious consequences. 4, poor layout, lack of a small number of notebook keyboard keys, compact areas, so the keyboard layout is different, and some notebook keyboard layout very unreasonable, some function keys have been set up all over, it is difficult to find, typing and use of inconvenient time. I used a WIN button to move to the upper right corner of the Toshiba notebook, indescribably more than the awkward.
5, configuration -
Notebook configuration single
Many of my friends often ask me, certain models of notebook memory frequency is how many, how much hard disk rotation, motherboard chip, etc. What is the specific configuration, this really is powerless to do anything, unable to give an answer. Now notebook production, as a result of the upstream manufacturers accessories inconsistent arrival period, while the production line can not be expected to lay-off, so basically does not violate the pledge and publicity than the configuration based on the existing parts to the assembly. So if they are for low-end notebook hard drive to install the 4200 pre-arrival for high-end books of 5400 to install the hard disk has not been to, and high-end books have been on-line production, only the hard disk, then 4200 will be installed to your hard disk to the books on high-end, low-end notebook late 5400 to have used high-speed hard drive. Memory will also do so. This will give the various batches of different products, configuration changes may be a phenomenon. For there is no public commitment to the hard disk speed, memory frequency, the motherboard chipset notebook specifications, manufacturers may be configured according to the actual situation and make adjustments, for consumers, may feel a headache, but in the absence of better solution approach before, only as far as possible to the actual configuration, whichever is the spot, in particular, must not listen to the media evaluation of the configuration, and to its commitments as the factory owners. Sixth, the battery - what can be long? Notebook batteries
Laptop battery life is a big problem, if there is no battery, the notebook we have to do, might as well buy a desktop LCD PC it, buy books, want is a mobility. Well, using the standard battery what is it? Under what circumstances the use of long regarded as normal? The so-called greatest life, what the concept of standby time is it? Now the notebook computer, the basic are in the use of lithium batteries, the benefits Needless to say, we all know very well. However, the number of batteries batteries, notebook configuration and power-saving mode of the situation of battery life are greatly affected. Generally speaking, a laptop, the battery was fully activated circumstances, in the case of running at full speed, should be able to guarantee the power supply for more than two hours can be regarded as normal. Note that the battery life by the number of battery charge and discharge is also very serious impact. Therefore, to minimize the frequent battery charging and discharging of extended battery life of notebook computers is very good. Seven or down - it sounds on the down-the case?
The use of energy-saving technologies Speedstep Pentium M processor Some of my friends in the purchase of mobile processors are equipped with notebooks, there will always be a problem plaguing that processors are often less than the nominal frequency is always lower than the nominal rate of speed, some friends think it is his notebook problems, in fact, this phenomenon is no need to greatly strained. As the notebook product is different from the desktop processor processor, the notebook processor for energy-saving considerations, mostly used, such as Intel's "Speedstep" and AMD's "Powernow" technology energy-saving technology, the processor can use the situation Analysis automatically reduce the frequency of use, so as to achieve energy-saving purposes. If there is a situation of low frequency of use and the effect will use your words, you can set up inside the BIOS option to turn off power-saving features and power options for the transfer of property has been open, so even in the the use of battery cases, the processor will run at full speed, of course, battery life will shorten the response, after all, both fish and bear's paw can not do. 8, invoices - should not be in the end should be?
Notebook purchase invoices Many of my friends in to buy a computer when there is a very confusing issue, that is, they should not be to the invoice, who for their own votes, what is the use of invoices. Invoices, commodity transactions, dealers issued to the purchaser to buy a valid certificate. Similarly, the official seal of the receipt also have the force of law, can prove that the process of commodity trading. The difference is, receipts can be easily purchased in stationery stores, and even pulling Zhang White on the issue, and invoices have to be determined by the purchase of dealers in sales after their invoices to pay taxes to the state. In other words, to the user is invoiced to pay taxes, and issuing IOUs or nothing to open, it is the tax evasion. Some dealers say that the development of votes can be let, it was precisely for this reason. Then why do some dealers can be very happy to users of the votes, while some dealers would rather not do business users not to vote? This was mainly affected by the current tax system in our country the status of the decision. Generally speaking, the notebook computer dealers are divided into two broad categories:
1, individual taxpayers and small-scale operators. The vast majority of these dealers, the way in tax, the use of fixed + fixed rate of tax to pay the way. In addition to a certain amount each month to pay the fixed tax, would also like to pay over the fixed rate of tax. The fixed rate of the general tax rate of 4 percent, which is 3999 yuan if a notebook of a particular model, if the development of votes, then they would have to pay a nominal amount of 4 percent tax: 3999X4% = 160 of $. The notebook and the actual profit was 49 million, if the development of votes, dealers may be money-losing 111 yuan, which have not remove the shipping and after-sale budget. So if you buy the notebook when the encounter is such dealer, then he would rather not do business users will not vote.
2, the general taxpayers. Dealers in the way of such tax, the general value-added tax in accordance with accounting, there is a sound accounting system. Profits by 17 percent value-added tax to pay. That is, if the same is a notebook of 3999 yuan, 3950 yuan input tax for the X17% = 671.5 million, sold for 3999 yuan of output 3999X17% = 679.8 million, to pay taxes for 679.8-674.5 = 8.3 yuan. Then there will be about 40 yuan in gross profits, as small-scale taxpayers will not like losing money. Therefore, it can give users votes. From the above two types of dealer types can be seen that the general taxpayer is based on a certain percentage of profits to tax, a profit before tax, the development of votes will not lose money. The self-employed taxpayers and small-scale is based on the fixed rate of sales to pay tax, high taxes, even as some low-priced Chinese-made small profits product development votes will lose money. This is why some dealers can be very happy to users of the development of votes, some not open, and the invoice can not let the roots of the problem. Another is the need to explain who is going to develop vote. This problem seems not to explain any further, on a word, no one who issued sales invoices. Does not exist to give the money to your dealer, but from a certain computer company or other person to develop the possibility of votes to you, the law does not support this.
To say one more thing here is that some people may ask, since the general taxpayer to pay taxes the way so reasonable, why small-scale self-employed taxpayers and taxpayers in general do not? The reason is simple, the general taxpayers need a registered capital of more than 500,000 yuan in annual sales of more than 1.8 million yuan, can only be a sound financial system. Nine, three bags - how specific package? Three bags of important certificate - warranty card
Three bags of the provisions of the country, the purchase of notebook products, such as occurred in the use of failure, 7 days , shifting within 15 days a year machine warranty, it is important parts warranty 2-3 years. This is the state's notebook manufacturers put forward by rigid rules, is to protect consumers from the point of view, as long as it is in China the production and sale of notebook business must be observed by all. As long as legitimate channels for consumers to purchase notebook products, are the state's three bags of policy. Some big brands even the whole of its production to provide the whole 3-year warranty, which is the protection of consumers is still very favorable investment, after all, a little notebook computer problems, maintenance costs are not a minority. But here is worth to remind consumers that the notebook does not parallel the state's three bags in the range. 10, upgrades - who is going to rise, how the security?
High-performance notebook hard drive After a lot of friends in the purchase, or even just when trying to purchase a computer or upgrade, change configuration, but at the same time worried about warranty issues after the upgrade. 1, who is going to upgrade. Bought a computer, some users would like to add memory, and some would like to change the hard disk, and even wish to move to another drive, and so who is going to work by the responsible? Generally speaking, these tasks involve a certain degree of technical content, should be considered by the professional and technical personnel to operate. While the sales of these accessories to your dealer will be happy to tend to the obligation for you to do this work. If you are looking for computer service stations to carry out this operation, is required to pay certain service charges. But it is certainly more in the warranty will be * and feel relieved to avoid future problems that may occur after the phenomenon of prevarication. 2, how the warranty?
The upgraded computer How does the warranty? What services are also to enjoy. Once a computer user to open the shell to replace or add accessories, users will no longer enjoy the three bags of包退and the whole shifting services, but without the user's vandalism of the original accessories you can continue to enjoy the repair service. After the user to add non-original accessories from the dealer responsible for these accessories, computer manufacturers will not be responsible. For example, you buy the books for the new increase of a memory, and later failure of the notebook keyboard, both of contact does not exist, then the notebook manufacturers should be free of charge for your repair, replacement of the keyboard. If this is your memory after a failure, certainly find your dealer to guarantee the memory. But if the memory is added after the failure of the motherboard can not boot, then the service station is likely to fault in accordance with the specific phenomenon to determine whether you replace the memory caused by man-made damage, the need for maintenance fees.
3, with special attention! Sometimes, some users of the service station to buy brand accessories to upgrade, but the problem still is not the manufacturers warranty, I am very puzzled. In fact, at this time will need to pay attention, you in the service station does not mean the purchase of accessories is available accessories manufacturers. Manufacturers provide to the service stations are generally maintenance free warranty with spare parts, not the promotion of retail to the user. The service station has the right to purchase some of their own Tesco sales of accessories to the user. This service station to buy and sell their parts to the users by the service warranty, and service stations belonging to the behavior of individuals, so the general computer company does not provide warranty. All notebook accessories are affixed to some of the original stickers, which is the purchase of 10 to pay attention to.
