Getway's 623c is about 4900,

HP's is around 3,906,5500.

The prices I told you above are generally close to the lowest price you can buy. This is the price in Nanjing. In the actual purchase, it may vary by region and person. Finally, I would like to remind you in particular that when purchasing machines, you must bring two or three people, neither too many nor too few. With fewer people, people are easy to cheat you, and with more people, you are ignorant. Don't be afraid to bargain, cut as much as possible, run around a few more, and don't be too tired. Only in this way can you buy a good machine and save money.

If you are a student, I remind you that it is best not to buy an HP notebook recently. Because HP's current notebook cannot be modified by xp driver, only vista can be used. Of course, you can buy it if you don't care. HP's 3803, 3807 and 3907 are all good, all around five or six thousand.

The old rookie came to sum up experience for the new bird ~ ~ ~

I noticed that a few new people came to our forum, probably all to buy Lenovo notebooks ~ ~ ~ I came first, just to welcome you on behalf of myself and the old-timers of Lenovo on the forum ~ ~ ~

At first, I thought that because everyone's needs are different, everyone buys notebooks in different ways and situations, so there is no need to send a post to summarize the experience too thoroughly. However, one thing changed my point of view. I just finished chatting with a senior sister on MSN, and learned that she just bought an HP notebook for 8900 yuan not long ago, and it was bought in the computer city. I almost fell off my stool when I saw the news. She didn't bargain with others, did she inspect the goods, and didn't even check the serial number. She just took an invoice that she didn't know was true or false. I told her that you bought it expensive, but she didn't think so. Instead, she is grateful to the profiteers, because the memory they gave her has been upgraded to 2G ~ ~ ~ (The wool is on the sheep! ) ~ ~ ~ From that moment on, I sincerely hate those profiteers who cheat ignorant girls! So I am posting now, hoping that my experience can help my friends who are going to buy notebooks for the first time.

I. Investigation visit:

A laptop that can keep up with the times costs 5 ~ 6 thousand yuan, and the masses don't care. Therefore, if you want to buy a good computer, you must do your homework first, that is, check the quotation more. There are many ways to get the quotation, which can be obtained from official website, a brand computer, or from reputable websites such as Zhongguancun, Silicon Valley Power, JD.COM and Pacific Ocean. If you have leisure time, you can also go directly to Computer City and try to compare the price with Kan Kan, a shop assistant. When you have a deeper understanding of the configuration you need and several suitable notebooks, you can put aside your work and school affairs and go to nearby reputable shopping malls such as Gome and Suning Appliance to ask all the questions you don't know and learn about the warranty, maintenance and performance of the machine. One thing I have to mention about the quotation is that there is a big difference between the official quotation and the actual transaction price. For example, I bought Thinkpad 7755-BJ 1, and the official quotation for licensed products is 15999, but my actual transaction price is only 9800. Generally, the price reduction space of imported brands is as high as 20%, and domestic brands also have 10%.

Of course, it is difficult to know the exact lowest transaction price, but the more times you go to the computer city to bargain, the closer you know the price is to the lowest price. Finally, you need to lock a certain machine, and then you can prepare to go to the computer city to buy it. Also, many novices are superstitious about buying channels such as specialty stores and department stores, and think that these channels are much safer. In fact, I think that as long as you have enough knowledge and preparation, there is no need to go to those places to buy computers, and it doesn't mean that you won't buy things with problems.

Second, the bargaining:

Before, our forum had a very detailed guide to bargaining methods, but I found that it was very different from the actual operation and was suspected of exaggeration and fiction. However, most of the content is still worth learning. I summed up a few don't and want:

1. Don't pretend to be a rookie!

Never pretend to be a rookie! Don't tell anyone even if you are a rookie! In fact, many salespeople are not very good at it, because large computer chain retailers often transfer personnel because of the situation, so some computer salespeople don't know much about the computers they buy, and some will meet you as novices and deliberately blow their computer performance to the sky. When I first went to Computer City to ask Sony for an offer, a middle-aged salesman told me that their notebooks had hard disk protection. I asked him if he could take it out for me, but he said he couldn't remember how. Later, I went to another Sony dealer and asked the same question. They said this machine didn't have this function.

2. Don't hesitate:

General salespeople will ask when to buy, because when they are sure that you are interested in buying, instead of simply asking the price, they may quote their low price. On the contrary, if you are hesitant and don't know when to buy, they will definitely say something like "the price fluctuates every day". In fact, except for special reasons, prices fluctuate every few days (I don't know if it's true), so they don't want to show their "cards" at all when they are not sure whether you want to buy them. So, when you are sure to buy it, you have already gone to the store and sat down. You have to tell them "I will buy it today". My classic opening speech is "ThinkPad R 617755-BJ1,make out an invoice, quote! After paying the money, move away immediately after the inspection. "

3. Don't give up easily:

If you fail to bargain with the salesman at first, don't flash the card immediately, and polish it as much as possible. This is just to prove to the salesman that you are serious about buying a computer, not just sightseeing or business espionage.

4. Don't charge big money:

Let the seller know that you are a smart consumer (I went to bargain at that time, and after the transaction, their manager couldn't help telling me: young people like you are rarely so smart), not people who don't care about money and computers.

5. Don't not invoice:

The invoice is definitely more important than you think. Even if an individual buys a computer instead of buying a computer for the company, an invoice must be issued. In order to avoid tax, the salesman will probably advise you not to invoice, but you should know that all your purchases are not guaranteed without invoicing. You want to buy licensed goods, they give you parallel imports, even if you have a mouth, you can't argue. In addition, if there is no invoice and the warranty period of your computer starts from the factory date, then you will lose a lot. In short, don't pick up sesame seeds and lose watermelon.

6. Don't be soft-hearted, and don't think you have earned it:

Merchants will definitely tell you something like "We don't make money for you". This sentence is absolutely unbelievable. Also, when buying a computer, some so-called "gifts" are actually original and standard, such as handbags, and some even include a mouse. Therefore, when you hear such a lie as "sending a bag to a mouse", you must expose him to his face.

7. Don't let the seller know your "psychological price":

General merchants will ask, "How much is the offer from others?" "What's your budget?" "How much do you think is reasonable?" Questions like this, the purpose of these questions is the same, that is, insight into your psychological price. When they know the price in your heart, you become very passive. Because your heart price is likely to be different from the real lowest price, after your heart price is exposed, the merchant will not adjust the price to the lowest price, but will look around your heart price. I suggest not to answer this question directly. It's better to say "it doesn't matter how much others give, the most important thing is how much you can give me" and "what price do I think is reasonable?" I think the reasonable price is 1000 yuan. " These questions should be cleverly avoided. If you go too far, you will usually make merchants mistakenly think that you are here to understand, not to buy.

8. Don't waste time with coolies;

I can guarantee that if you go to 10 coolies and 10 store managers to bargain, the chances of getting the most suitable price and purchase method from the store managers are much higher than those of coolies! Store managers are more experienced, they can tell which are potential buyers and which are not, and they will give you a low price without wasting too much time. Of course, the most important thing is that they have the right to release this low price and have the right to choose which concessions to give you. Although coolies may say they can make these choices, even if they can, they will be much more conservative. Dealing with the store manager also has disadvantages, that is, they have too strong insight into consumers, and you may be confused by him and lose your own principles if you are not careful. The skill requirement of bargaining with the store manager is actually nothing, that is, you must be smart and active psychologically. As long as you can take the initiative and resolutely defend the principle of low price, high quality and safety, the manager's old fox can only serve you. In addition, the salesman will usually let you pay the money first and then inspect the goods. This must not happen! Because if your inspection is not up to standard, when you ask for a replacement, if they say "this is the last stock", you can only eat coptis. If they ask you to pay a deposit, you can, but you must formally write down the request for refund of the deposit and indicate the price of the deposit before paying it. They ask you to charge a deposit. I think it's not that you don't have confidence in your goods, but that suppliers may charge them "unpacking fees" If they take your deposit, they can ensure that you will not negotiate with other merchants after unpacking, so as to avoid their loss of unpacking fees.

I think the most important thing in bargaining is chips. The more chips, the higher the efficiency. Your chips can be your knowledge, your mastery of quotations from other retailers, your bargaining power and so on. The following is my own memoir of bargaining (simplified version):

Me: (entering the door, sitting down, cross-legged) Do you have 7755-BJ 1? Bid for those who have tickets. It is agreed to inspect the goods first, then pay the money, and move out when you are ready.

Shop assistant: OK (check the quotation and type it out for me with a calculator: 1 1000).

Me: (sneering) Your price is the media price (actually it is not). It's ok to cheat Martians. I come from the earth. Please give me an acceptable price for the earth.

Shop assistant: (smirking) OK, I'll quote you the lowest price (press 10500).

Me: No way! Talk to your store manager ~ ~ ~ To tell you the truth, the prices of American X company downstairs and nearby Ai Y company are much lower than yours! (Company X offers 9800. Company Y offered 9900, and neither of them wanted to send anything. They asked me to pay the money first and then inspect the goods.

Manager: Have a cup of tea, sir ~ ~ ~ What did you say they offered you just now? We can do what they can.

Me: I can't say their price, but their price is much lower than yours.

Manager: Please make an offer, sir, and we will try our best to help you.

Me: It doesn't matter what I ask, what matters is what price you can give me. I want 5000 yuan!

Manager: No, no, that's impossible ~ ~ ~

Me: Then make a sincere price ~ ~ ~

Manager: (according to the calculator: 9900) I'll give you the cost price ~ ~ ~

Me: Hehe (sneer), your price is lower than yours. Of course, this is not your cost price. If you want me to stay here and buy it, you should give me a more sincere price, otherwise you will send something.

The last part is omitted. Anyway, I have a deal at this price. I will be given headphones, cleaning solution, keyboard film and camera, and I will be exempted from the electronic account fee (generally 8 ‰).

Me: The inspection should be carried out according to my standards. There can be a bad bright spot and a dark spot on the screen. I don't care about any national standards, I use my own testing software to test the performance. Anything I am not satisfied with must be replaced, otherwise the deposit will be refunded. (The test software can be downloaded for free from the "Private Software Sharing Area" of this forum. You should write down my deposit refund standard and have a receipt. . .

Manager: OK, OK! ~~~

The last step is to check the machine ~ ~ ~

Its experimental machine is not difficult ~ ~ I have explained in my previous reply to sunshinetown's post ~ ~ I am not good at distinguishing the authenticity and parallelism of institutions. I suggest you call Lenovo's service hotline: 800 8 10 5546.

~~~

Ok ~ ~ ~ write here, I think it's almost enough. I'll add anything if I find it later ~ ~ ~ Qi Xin works together to deal with profiteers in Qi Xin!

PS: If a girl is thin-skinned, it is strongly recommended to bring a man to bargain, use his face to make up for your shortcomings, and be brave when dealing with JS.

Five Taboos of Notebook Hardware

First of all, the battery should not be charged frequently.

I always show off the natural scenery of the laptop I just bought to my friends and introduce which ones are the most pleasing. In this way, it is logical for the battery to alarm frequently. Plug in the power nearby and you can continue. In this simple action, there is a killer to the notebook computer-greatly shortening the life of the battery. The best way is: when using the laptop for the first few times, the remaining power in the laptop battery should be completely used up, and when the laptop can no longer be turned on, it should be fully charged for 4 ~ 6 hours when it is turned off. (In principle, it is best not to start working while charging, which will prolong the charging time. Even after charging for 4 hours, although it shows 100%, it may be virtual electricity, so the pure charging method is advocated. It is best to take out the battery after charging. If possible, use the lighting power directly at ordinary times. Once the battery is activated, you must insist on running out of storage space before charging. Only in this way can the battery work stably for a long time. (Editor: Ni-MH battery is like this. For this edition of "How to charge the battery?" There are different views in this article. )

Second, avoid clicking the mouse.

As we all know, there are two kinds of "notebook computer" mice, one is pressure-sensitive and the other is touch-screen. Both have their advantages and disadvantages. The pressure-sensitive action is simple, and the range of pointer movement is the whole desktop. However, many people can't grasp the best pressure. Some people hold down the mechanical mouse just like learning to use a microcomputer, thus slowing down the pressure-sensitive response prematurely. The touch screen type is a rough layer of PVC-like material. In the process of use, if the finger is dry, the pointer will not move well and the range is very small. Many people deal with this situation by rubbing and pressing hard at the same time. In the long run, it will not only scratch the surface, but also make the mouse no longer flexible. The best way is: the former should be lightly pressed and lightly moved, and the latter should always wipe the surface with a soft cloth (glasses cloth). When using it, your fingers are slightly moist to reduce friction and make you move freely.

Third, don't "frequently wipe" the screen at will.

The screen is the main reflector of man-machine conversation, which allows you to monitor every move of the microcomputer in real time. But the composition of the LCD screen determines that it is more delicate, especially the surface. Users often talk while working, and there will definitely be some stains on the surface. Some users will be very concerned at first, but they will be erased directly with a wave of their hands. If you are not careful, the screen will be scratched. The phenomenon is not obvious at first, but over time there will be color, light and shade and some physical scratches. The best way is to gently wipe the surface of the display screen with a clean soft cloth dipped in some neutral liquid that is neither oily nor irritating, and then dry it with a dry soft cloth.

Fourth, don't play the optical drive for a long time.

Many friends go out for meetings and travel, and often bring "notebooks". People can use them to entertain and prepare materials in the car, but most people still watch CDs and listen to music. This is simply killing the life of the optical drive. Notebook computer is named because it is small, and CD-ROM drive is one of them, and it is a big radiator. Working for a long time will greatly shorten the life of the laser head, and overheating of the computer body will lead to premature aging of some plastic parts inside. The best way is to copy some favorite CDs and VCDs to the hard disk, which can reduce the heat source and prolong the life of the notebook.

Five, the whole machine to avoid oblique vibration.
