1. First ask the price directly state your intention, I am here today to get the computer, I hope you quote a minimum price, I may compare on a few, if your is the lowest I will take your. (Now do not buy a computer ask price a lot of sales are most afraid of this)
2. At least ask for more than three. Watch to see if any of them have activities. The gift from the event is still very good. If you don't want gifts, they can be less money.
3. Laptops are definitely all right, ask if it's the original bag and original mouse, and what comes with it. If it's not the original mouse and bag etc then show him how much less he can get.
4. Ask about the warranty, HP is generally 2 years, invoiced how to guarantee, not invoiced how to guarantee, and open or not invoiced price is not the same. Probably about 100 less money. Generally do not invoice, he gave you to get a copy of the invoice to take as usual can be the national warranty.
5. After verifying the price of all the accessories and so on, but also to see the configuration of the computer, and whether you choose to be consistent, because the same model of laptop computers have low-end and high-end type. Don't just look at the model number. You will not, let the point of sale to show you the configuration.
6. More grinding, let him remove the last zero. Also send you a few small things. For example, colorful inner bag, LCD screen protection kit, nice mouse pad, etc..
Laptop computer purchase should pay attention to the following points:
One, open the box - how to determine JS take to me is not a new machine?
Many users and friends to buy this book do not like to open the seal of the machine, mainly because of the fear of encountering reworked machines or dealers have been tampered with, replacement parts. However, in fact, did not open the seal of the book often encountered, such as only a few days of the prototype, such as just opened to other users have seen the goods, etc., these cases do not mean that the machine has a problem, is completely safe to buy the machine. And those sealed well inside the box containing the book is not necessarily not opened, because a wind turbine can completely solve the seal on the packaging of the book, without leaving a trace. So when you buy a notebook, to buy a new machine, but does not mean that there is no seal is still well affixed to the notebook is necessarily a new machine, also does not mean that the unpacked box of the notebook can not be purchased. The key is to see if the book is a new machine. Here are a few tips on how to identify if a laptop is new:
1, look at the serial number. Most of the laptop body and battery should be affixed with the same serial number number, if the battery serial number and host serial number is not consistent, this book is very likely to have been replaced by the battery; In addition, in the procurement of foreign brands of laptop products, whether the body serial number and the battery and the packaging on the same is to test the product is not a very important basis for parallel imports, we must know that foreign parallel imports of notebooks can not in the The first thing you need to do is to get your hands on a new laptop and get it to work.
2, look at the anti-theft lock hole. If there is a mark, that inserted the laptop anti-theft lock, it is very likely to have done the prototype;
3, look at the foot. If there is wear and tear and very dirty, that was used, the production line bench is not so dirty;
4, look at the cooling fan. If the fan blades already have a thin layer of dust, indicating that the use of up to more than a week;
5, look at the production date. Three months before the factory of this book is still on the market, we must pay attention to. Electronic products sales update very quickly, it is impossible to let a book press so long in the channel.
6, look at the keyboard. New notebook keyboard is very clean, but not shiny. Used notebook keyboard crevices will have dust, commonly used a few keys will be worn shiny;
7, look at the screws. This is not much to say, right? Screws have been removed? Then it's better to turn around and go!
8, look at the seams. Be dealt with refurbished this book, the seams are generally very difficult to deal with as new, such as the small gap between the AB side of the screen of this book, such as the gap between the CD-ROM drive, and even MODEM and PCMCIA card interfaces, if you can find the accumulation of dust, you can be sure that as far as the prototype has been set up, and not sealed well. What? I also found the cotton wool used to wipe the notebook? I don't need to ask again what to do.
In short, to see if the book is new, you can't generalize whether the outer box has been opened. It's not necessarily true that the opened box is not a good one, on the contrary, the prototype is usually the most reliable one. On the contrary, the prototype is generally the most reliable notebook. On the contrary, the notebook in the intact package should be identified with more care. The most important thing is to be careful when selecting.
Two, bad spots - how much is too much?
Screen bad detection of good tools - NOKIA Ntest
LCD screen, buy a laptop is the biggest headache of bad points, after all, who would not like to buy their own new laptop on a few big bright spots, right? But almost no manufacturer promises to be free of bad spots. Notebook manufacturers, only ASUS commitment to no bright spots, but you can go to ASUS forums to see, this is just a word game, to the death of the dark spots more, can not stand ah! And they call points with color as color points, not bright spots can not be guaranteed, so now by this standard calculation, bright spots are what is really hard to say.
LCD bad point problem plagued the LCD industry for a long time, due to manufacturing technology itself, LCD bad point is difficult to avoid, but how many bad points is normal. At present, the LCD manufacturing community has never given a statement, in the end, how many bad points is normal, in fact, the emergence of bad points is the liquid crystal display body of a single crystal does not work properly, there may be red, blue, green different defects.
The root cause of the emergence of bad points are in the production, if the transportation of the problem or the use of a long time to appear to answer are prevarication. Because the bad spot in the LCD screen crystal composition of the moment has been doomed, only some of the time in the factory did not show, or some of the problems are not serious, only after a period of time in the use of the gradual change into a dark spot (dimming of the light). In other words, the possibility of bad dots is very small. So if you buy a notebook with bad dots, you don't have to worry about them spreading.
The LCD screen for the bad points, is really a helpless topic, in general, the purchase of this book, the LCD screen over three bad points, especially the existence of bad points in the A area, then you can refuse to buy. In the selection of this book, here we recommend that you can bring some screen test software for detailed testing of the screen, be sure to please carefully select before you buy, so as not to bring unnecessary trouble in the future.
Three, the fan - it should not turn in the end?
Laptop cooling tool - fan
Laptop fan and desktop is not quite the same, is subject to the laptop temperature control (except for some individual desktop CPU laptop). That is to say, when the temperature is high, the fan will run faster, and when the temperature is low the fan will slow down or even not work. The benefits of this is to save power, two is to reduce noise, three is to extend the life of the fan. Generally speaking, notebook fan speed can be adjusted in the COMS settings by adjusting the power saving mode. There are also some notebooks that have a full range of COMS settings, so you can directly set the fan operating temperature and speed. Some friends think that the notebook fan noise, always want to stop the fan work, the fan startup temperature is very low, this will make the CPU and system temperature overheating, resulting in crash and reduce the service life of the relevant accessories, there is no benefit, so the laptop fan, frequent turn is not good, do not work is also unfavorable, we must master a good degree.
The general experience is that in the room temperature of about twenty degrees when the room is well ventilated, surfing the web, Centrino CPU laptop fan, should be in the interval of twenty to thirty minutes to start, work about five minutes to stop working to save energy. When playing games, about ten minutes to start once. If the usual operation has also been working like crazy, then it should be tested to see if there is a problem with the COMS settings or temperature control circuit.
Four, the keyboard - what is the feel?
Laptop keyboards with Chinese logos
Many friends and some media review room reviews, will say the so-and-so laptop keyboard feel how how, in fact, this is the most difficult to measure the sentence. Notebook keyboard key range is much shorter than the ordinary desktop keyboard, itself is very uncomfortable. So the feel won't be too good. And everyone has different preferences for the elasticity and softness of the keyboard keys, so it's not objective to say how the keyboard feels based on your own experience alone.
A good laptop keyboard, to do:
1, gap enough, generally 12 inches below the laptop, its keyboard tends to use a tight design, the distance between the keys is very close, playing the word is very uncomfortable.
2, the keys firmly, some bad laptop keyboard keys, press a corner of the time, the other corner will even be warped, so play the words, the keys wobble, is very difficult.
3, the overall flat, notebook keyboard is very thin, often installed below the notebook memory, hard disk and other accessories, some notebook keyboard below the design of the irregular, some places have accessories, some places are empty, plus the keyboard itself is very thin steel lining, typing, below the lack of accessories place will have the feeling of subsidence, not only uncomfortable, and even feel the press fall down, press the broken It's not only uncomfortable, but even scary to press down and break the keyboard. When you look at the keyboard from a lower angle, you can even see that the keyboard is wavy and uneven. Such a keyboard is even more terrible is that the high temperature of the work of this book, the keyboard will make the keyboard up slightly bulging, and after the shutdown and close the screen, bulging keyboard has not returned to its original position, but will rub the LCD screen, resulting in the LCD screen printed on the keyboard layout and the same scratches, can not be repaired, but also affects the warranty. That would have serious consequences.
4, the layout is poor, the notebook keyboard lacks small number keys, place and compact, so the layout of the keyboard has its own layout, some notebook keyboard layout design is very unreasonable, some function keys set up to get everywhere, it is difficult to find, typing and use of the time is very inconvenient. I've used a Toshiba laptop that moved the WIN key to the upper right corner, not to mention how awkward.
V. Configuration - in the fog.
Notebook configuration in the fog
Many friends often ask me, a certain model of notebook memory frequency is how much, how many hard disk revolutions, what is the motherboard chip, and so on the specific configuration, for which there is really nothing to do, can not answer. Now the notebook production, due to the upstream manufacturers of parts arrival period is not consistent, and the production line can not be stopped to wait for materials, so basically in not violating and lower than the publicity commitment on the basis of the configuration, with the existing parts to assemble. So if you encounter for low-end notebook installation of 4200 rpm hard disk first arrived, for high-end notebook installation of 5400 rpm hard disk did not arrive, and high-end notebook has been on-line production, only missing hard disk, then 4200 rpm hard disk will be installed to the high-end notebook, the later low-end notebook but used 5400 rpm high-speed hard disk. The same goes for memory. This gives rise to the phenomenon that the configuration may vary from batch to batch. For no public commitment to hard disk speed, memory frequency, motherboard chipset specifications of the notebook, the manufacturer may be based on the actual situation to make adjustments to the configuration, for consumers, may feel a headache, but in the absence of a better solution before, can only try to the actual spot configuration shall prevail, especially do not listen to the media review of the configuration, and take it as a promise of the manufacturer.
Sixth, the battery - how long can actually use?
Laptop batteries
Laptop battery time is a big problem, if there is no battery, what do we want to do with the laptop, might as well buy a desktop LCD computer it, buy a notebook, to be a mobility. So what is the standard for battery use? Under what circumstances how long is considered normal? The so-called maximum life time, standby time are what concept? Now the laptop, basically in the use of lithium batteries, the benefits need not be said, we are all very clear. However, the number of battery cells, the configuration of the laptop and the situation of the power saving mode have a great impact on the battery time. Generally speaking, a laptop, the battery power is fully activated in the case of full-speed operation, should be able to ensure more than two hours of power supply to be considered normal. It is important to note that battery life is also heavily influenced by the number of times the battery is charged and discharged. So minimizing the frequent charging and discharging of the battery is good for extending the battery life of your laptop.
Seven, downclocking - how did it downclock?
Using Speedstep energy-saving technology Pentium M processor
Some friends in the purchase of a mobile version of the processor equipped with a laptop, there is often a problem is plagued, that is, the processor tends to be less than the nominal frequency, is always lower than the nominal frequency of the speed of the operation, some friends think that his laptop problems, in fact, this phenomenon is greatly need to be nervous. In fact, this phenomenon is greatly need not be nervous. Because the processor of notebook products is different from the desktop processor, these notebook processors for energy saving considerations, most of them use such as INTEL's "Speedstep" and AMD's "Powernow" technology energy-saving technology, the processor can be analyzed by the use of the condition of the processor, the processor can be analyzed by the use of the condition of the processor. The processor can automatically reduce the frequency of use through the analysis of the use of the situation, so as to achieve the purpose of energy saving. If you've got a problem with the frequency of use, you can turn off the power-saving option in the BIOS settings and leave the power option on all the time, so that the processor will run at full speed even when using the battery, and then the battery life will be shortened.
Eight, invoices - in the end should be?
Notebook purchase invoice
Many friends in the purchase of computers, there is a very confusing question, is their own should be invoiced, who should give their invoices, invoices have what use. Invoice, is a commodity transaction, the dealer issued to the buyer of a valid proof of purchase. Similarly, a stamped receipt is also legally valid to prove the process of commodity transaction. The difference is that the receipt can be easily bought in the cultural supplies store, or even pull a piece of white paper on the issuance, while the invoice has to be purchased by the dealer from the tax authorities, and after the sale of invoices to the state to pay taxes. In other words, the invoice to the user is indeed taxed, open a white note or nothing, it can be tax evasion. Some dealers say they can make a profit without invoicing for this very reason. So why some dealers can be very fast to the user invoices, while some dealers would rather not do business also do not give the user invoices? This is mainly determined by the current state of our national tax system.
Generally speaking, laptop dealers are divided into two categories:
1, small-scale taxpayers and self-employed. These dealers accounted for the vast majority of the tax method, the use of fixed + fixed-rate tax payment. In addition to paying a certain amount of flat-rate tax every month, they also have to pay an excess flat-rate tax. General fixed-rate tax rate of 4%, that is, if a 3,999 yuan of a certain model of laptop, if the invoice, then you have to pay the ticket amount of 4% of the tax: 3,999 X 4% = 160 yuan. And the actual profit of this laptop is $49, so if the invoice is issued, the dealer may lose money $111, and that's before shipping and after-sales budgets are removed. So if you buy a laptop when you meet this type of dealer, then he would rather not do business than invoice the user.
2. General taxpayers. This kind of dealer in the way of taxation, generally according to the value-added tax accounting, has a perfect accounting system. According to the profit of 17% to pay the value-added tax. That is, if the same is a 3,999 yuan laptop, input tax is 3950 yuan X 17% = 671.5 yuan, selling 3,999 yuan output tax is 3,999 X 17% = 679.8 yuan, need to pay taxes for 679.8-674.5 = 8.3 yuan. Then there will still be about 40 dollars of gross profit, not like small taxpayers lose money. So it is still possible to invoice the user. From the above two types of dealers can be seen, general taxpayers are a certain percentage of profits to pay taxes, there are profits to pay taxes, invoicing will not lose money. And self-employed and small-scale taxpayers are based on a fixed rate of sales to pay taxes, taxes are very high, and even like some domestic low-priced, thin-profit products, invoicing will lose money. That is, some dealers can be very quick to develop invoices to the user, some would rather die than open, and some do not want to invoice can be the root cause of the profit. Another need to explain is the question of who should be invoiced. This issue does not seem to need more explanation, just one sentence, who sells who issued the invoice. There is no possibility, nor is there legal support, for you to give your money to a dealer only to be invoiced by so-and-so computer company or someone else.
There is one more thing to say here is that some friends may ask, since the general taxpayer's tax method is so reasonable, why small taxpayers and self-employed people do not do general taxpayers? The reason is very simple, general taxpayers need registered capital of more than five hundred thousand dollars, annual sales of more than 1.8 million yuan, sound financial system can be.
Nine, three packages - specifically how to package?
Three packages of important evidence - warranty card
National three packages of the provisions of the purchase of notebook products, such as the use of faults, within 7 days of the return, within 15 days of the replacement, one year of the whole warranty, the warranty of important parts 2-3 years. This is the state of the notebook manufacturers to put forward the mandatory provisions, from the point of view of this protection of consumers, as long as the production and sale of notebooks in China must comply with the enterprise. As long as consumers in the proper channels to buy notebook products, are enjoying the national policy of three packages. Some big brands and even its production of the whole machine to provide a 3-year warranty, which is to protect the consumer's investment is still very favorable, after all, a little problem with the laptop, the repair costs are not a small number. But here it is worth reminding consumers to pay attention to is that the water goods notebook is not in the enjoyment of the scope of the national three packages.
Ten, upgrade - who will rise, how to guarantee?
High-performance laptop hard disk
Many friends in the purchase of the machine, or even just purchased the machine when you want to upgrade the computer, change the configuration, but at the same time will be worried about upgrading the warranty.
1, who will upgrade.
Computer to buy, some users want to add memory, some also want to change the hard disk, and even want to change the CD-ROM drive, so who is responsible for the work? Generally speaking, these jobs involve a certain amount of technical content, should be operated by professional technicians. The dealer who sells you these parts will often be happy to volunteer to do this work for you. If you have to go to a computer service station, you will have to pay a service fee. However, the warranty will be more reliable and reassuring, avoiding the possibility of passing the buck when problems arise in the future.
2. How is the warranty?
How is the warranty for the upgraded computer? What other services are available. Computer a user to open the shell to replace or add accessories, the user is no longer enjoy the three packages in the package and the whole machine package replacement services, but without the user's man-made destruction of the original parts can continue to enjoy the package repair services. After the user added non-original parts by the dealer of these parts, the computer manufacturer is not responsible.
For example, if you add a memory stick to your newly purchased laptop, and then the laptop's keyboard malfunctions, and the two are not connected, then the laptop manufacturer should repair and replace the keyboard for you free of charge. If it is the memory you added later that fails, surely you have to go to your memory dealer for warranty. But if it is after adding memory motherboard failure can not boot, then the service station is likely to be based on the failure of the specific phenomenon to determine whether you replace the memory caused by human damage, whether you need to charge for repairs.
3, special attention!
Sometimes, some users in the brand's service station to buy the parts for upgrading, but after the problem, still do not get the manufacturer's warranty, very confused. In fact, this is the time to pay attention to, you in the service station to buy parts is not the same as is the manufacturer to provide parts. Manufacturers provide to the service station is generally free of charge warranty period for maintenance of spare parts, and does not promote retail to the user. But the service station has the right to buy some easy to purchase parts sold to the user. So that the service station to buy and sell their own parts to the user by the service to warranty, belonging to the service station's personal behavior, so the general computer is the company does not provide warranty. Where the notebook original parts are labeled with the sticker, which is also the purchase of ten attention to the problem.
