Check the appearance carefully to see if it has been disassembled or cracked. If you find this kind of problem, don't buy it at any price. But if it's just some minor scratches, it can also be considered, because for the sake of maneuverability, some small friction is inevitable. And buying a second-hand notebook computer depends on the thickness, size and weight, compared with similar second-hand notebooks. Who chooses depends on his actual needs.

Step 2: Observe and check your LCD screen carefully.

This is very important. As we all know, LCD screen is the most expensive part of notebook computer accessories, accounting for 20%~35% of the whole machine cost. Therefore, we should pay special attention to: 1, whether the screen is damaged, because the machine with traces will be used for a long time, and the refraction of light will seriously damage people's vision. It is not cost-effective to accidentally move back to the machine that affects vision. 2. Carefully observe the size and display effect of the display screen, and consider the display effect and size of the display screen in combination with the price. Of course, it can also be used to reduce the price. 3. Identify the color of the display screen in detail. In addition to observing whether the screen is sixteen-color, 256-color or sixteen-bit true color and 24-bit true color, we should also observe it obliquely from top to bottom, left and right. If you can accurately see any color on the screen, you can judge that it is true color. Otherwise, if the color can only be recognized by observing it directly, it is pseudo color. You can hold a high-priced and high-quality LCD monitor in the business office and put it next to the notebook you want to buy. Under the same interface, compare their brightness, contrast, reaction speed, visibility and other parameters. 4. Pay attention to the delay performance and brightness of the display. When choosing a liquid crystal display, the most important thing is its delay length. If the delay is too long, your eyes will feel very tired. At the same time, brightness is a weakness of LCD. Generally, the brightness of popular LCD is 200cd/㎡ (lumen), and displays below this brightness are not desirable. Also, when looking at brightness, don't just look at brightness, but look at it with contrast adjustment. Some liquid crystal displays have the same brightness no matter how they are adjusted. As a result, when the contrast is improved, it looks dazzling and uncomfortable. In short, the eyes look comfortable and beautiful. 5. Pay attention to the bad points of the LCD screen. The most common ones are white spots and black spots. When you buy it, you can use the following simple methods to identify it: the general method of identifying black spots is to turn the whole screen background into a white screen, so that black spots can't escape your eyes; White dots are just the opposite. Turn the screen background to black, and then the white dots will show their true colors! However, in addition to white and black dots, there are sometimes dots of other colors. At this time, consumers can establish a red, yellow and blue screen background for simple identification.

Step 3: Carefully identify and test the components of the notebook.

Carefully check the CPU, hard disk, memory and other components of the notebook computer. When buying, you'd better take apart the machine and see for yourself. In addition, we must be alert to the despicable practice of profiteers using second-hand notebooks to replace notebook CPU with desktop CPU. Because the CPU with the same frequency will not be noticed by ordinary users, but the CPU using desktop and notebook is completely different. Due to the problem of different calorific value, the heat emitted by CPU cannot be emitted in the notebook, which leads to the instability of the system. Therefore, in the process of purchasing, it is required to conduct on-site inspection of CPU as much as possible. As for the hard disk, because we can't know the advantages and disadvantages of the hard disk by visual inspection, we can only detect it by software. The detection software can be DM, Norton, etc. After scanning with DM and Norton, DM takes a long time and Norton takes a short time. The scanning process must be smooth and consistent. If any cluster takes too long, there must be something wrong. As for memory, the memory of second-hand notebooks ranges from 32M to 256M. Try to choose a memory larger than 64M, preferably above 128M. Memory is replenished when purchasing, because some laptops have special memory, which has been discontinued and cannot be replaced. In addition, other built-in devices, such as video cards and sound cards, should also be checked face to face.

Step 4: Check the interface of the second-hand notebook computer.

Because it is very necessary to have a complete interface. In today's notebook computers, with the popularization and application of external storage devices, USB interface has become a necessary device for desktop and notebook computers, and USB interface is a very important interface. Therefore, it is best to buy a second-hand laptop with USB interface. In addition, the infrared transceiver function is also an indispensable function of the notebook now. Moreover, when buying a second-hand notebook, an important purchase condition is to look at its internal power supply. External power supply is necessary, and it is absolutely impossible without battery, so the power supply mainly depends on the quality of the battery, that is, the service life of the battery. Second-hand goods, Ni-MH batteries usually last for one hour or two, and lithium-ion batteries can last for two hours. This is the most basic requirement, otherwise it will not be considered.

Step 5: Check the status of peripheral devices.

Check whether the keyboard, mouse, CD-ROM drive, floppy drive and modem are available and easy to use. Last time I saw the keyboard of a second-hand notebook in the second-hand market, it was shiny and badly worn. In that case, I don't need to buy it. It costs hundreds of dollars to change a keyboard. At the same time, open a word processing software to see whether each key on the keyboard is available and whether the mouse is flexible. Whether there is a built-in floppy drive, CD-ROM drive, modem, etc. Both, please try them one by one, as long as the equipment in the computer can't be missed!

Step 6: Strive for the after-sales service of second-hand merchants.

This should also be the last step. Remember to take back all accessories (battery, power cord, etc.). ) drivers for this notebook, such as video card, sound card and communication card, are also needed, but most manufacturers say they don't have them. It doesn't matter without a driver. You can download a complete set of device drivers for this kind of computer from the website of the notebook computer manufacturer. Finally, second-hand notebook computers usually have a warranty period of two or three months, so the dealer must write the warranty period on the invoice, and during this period, conduct several tests on your second-hand notebook to find out all hidden problems. Otherwise, after the warranty period, you will be in trouble if you want to repair this kind of computer, especially the hardware part, and you must consider whether it is convenient to repair it in the future. If you can't buy accessories, you can't take them even if the machine is cheap, because the internal space of the notebook computer is small and there is a shortage of parts.

Second-hand laptops may go on strike at any time after they are bought because they are "weather-beaten", so how can you ensure that the second-hand laptops you buy are worth the money? In fact, it is not difficult to do this, just do the following identification.

Heat dissipation performance should be the focus of attention.

The heat dissipation performance of notebook computer directly affects the working performance of notebook computer, and it can also test whether the material of second-hand notebook computer is good. When checking the heat dissipation, it is best to connect the laptop to the power supply for a period of time, and then feel the temperature of the laptop shell by hand. If you feel hot, the heat dissipation effect of the second-hand laptop you choose is not good. If it runs for too long, the laptop may crash.

Bad point detection, the work that must be completed.

Because the LCD screen is directly related to the user's visual experience and the service life of the notebook computer, it is an inevitable step to carefully check whether there are any bad points on the display screen of the notebook computer. In fact, bad pixels are pixels that are opaque or transparent or even fixed in color on the LCD screen with pure black background or pure white background. If the display screen has more than five bad pixels, you can't buy it, because as time goes by, the number of bad pixels will increase until the whole display screen can't display normally.

Performance testing is the "top priority"

Check the overall running performance to verify whether the laptop you are buying is still worth buying. Check whether the mouse responds quickly, whether the touchpad is easy to use, whether the program runs normally, whether the screen display effect is clear, whether the notebook computer is noisy when running, and whether the notebook computer often crashes after working for a long time.

Auxiliary equipment must never be neglected.

Because most of the auxiliary devices of second-hand notebook computers have been used for a long time and may lack stable performance, the frequency of failures is very high. Once a fault occurs, it is difficult to repair. Because the auxiliary equipment of second-hand notebook computers are mostly old-fashioned, and the old ones are on the verge of extinction in the current notebook computer market, it is of course difficult to find a match with the old auxiliary equipment; If you switch to other equipment, it may affect the working performance of the whole notebook computer because of the poor compatibility of the second-hand notebook computer, and even make the notebook computer unable to continue working. Therefore, users must check whether the keyboard, floppy drive, CD-ROM drive and other auxiliary equipment are in good condition.

Complete accessories are the lowest "threshold"

The user manual in simplified Chinese in the attachment can guide you how to use the notebook computer correctly, especially the drive disk and system recovery CD in the attachment. Otherwise, many devices in the reinstalled system can't be driven correctly, so read the accessories in the original package carefully when purchasing.

Power supply specifications should not be underestimated.

At present, many second-hand laptops are foreign brands. For example, the power specifications of many second-hand notebook computers in Japan are 1 10V. Obviously, such a computer can't be used under the power supply of 220V V. Therefore, users must verify the specifications of the power supply to avoid unnecessary troubles caused by power supply problems.

Network functions should also be paid attention to.

Now, the main use of computers is surfing the Internet. If the laptop we buy doesn't even have the most basic LAN card or built-in modem, then we can't surf the Internet.

Formal places should be the only places to go.

After all, buying a second-hand laptop is risky. In order to minimize the risk, you'd better find some large businesses specializing in second-hand notebook computers. The second-hand laptops they provide are usually of good quality, and they also provide certain warranty service, and the configuration is relatively high, but the price may be a little more expensive. It is also a good choice to buy second-hand laptops through them.

The rise of notebook computers in China is in recent years. However, under the overwhelming publicity of major manufacturers, coupled with the portability, mobility and dazzling of notebook computers, many users are still willing to buy a notebook computer they like. However, laptops are expensive. Wealthy users will certainly buy expensive new machines. Friends who really want laptops without money can only go to the second-hand market and hope to find cheap models. Because of the actual needs of my work, I spent a month softening the foam and grinding it hard after repeated thinking. Dear parents finally agreed to buy a second-hand laptop. Now I write out the whole process of buying a second-hand notebook computer, from checking information to stepping on the spot, to purchasing a machine, and finally to invoicing and paying for it, and share it with all friends who want to buy a second-hand notebook.

Intelligence gathering

After being affirmed by my parents, I rushed my kitten online to read the information according to the habit of buying computers before. As the saying goes, "know yourself and know yourself, and you will win every battle." You can look at the whole market of second-hand laptops on the Internet now. Although there are some differences in quotations from all over the country, the differences are certainly not very big, so you don't have to be afraid to read JS's quotation first, and you can also make clear the notebook model you need. At the same time, I also learned that the sources of second-hand notebook computers can be roughly divided into the following categories:

1, personal sale (individual users buy their own machines for various reasons, and some even trade with their own machines at merchants. In general, the quality and color of this machine are better, because individuals will cherish their own machines.

2. The machines sold by the company (the machines sold by companies that need to upgrade are generally not very good in color, because the company uses a lot of people and hands, which are basically used frequently with high intensity. Of course, machines wear out quickly, and some machines will have some minor problems. The best thing about this kind of machine is that it is large in quantity and easy to choose.

3. Assemblers and refurbished machines (There are quite a few typical machines sold by JS in the market. The gentle JS just replaced the original memory or hard disk, while the vicious JS replaced all the hardware, even the LCD screen. Then put the corresponding hardware on other machines with many problems, and some repainted them to buy a good price.

4. foreign garbage (the foreign garbage mentioned here includes the accumulated goods of manufacturers. The performance of this kind of machine is uneven. If you are lucky, you can buy good machines. You can cry slowly if you are unlucky. Because it is imported, some machines have some problems in use.

Black goods (so-called stolen goods, stolen goods) are generally good in color and performance. As for whether to buy it, what's the problem after buying it?

Finally, after reading the opinions of n experts, I decided to go to the computer city first, mainly to see what the local spot is and how the price is. To put it bluntly, go to the computer city to find out what the merchants are selling, what notebooks are selling and what the price is. After 4 hours 12 minutes of hard work, we finally completed the market survey and initially selected a large merchant with more cash. This is also the habit of buying computers in the past, because there are businesses of a certain scale that do better and have a good reputation. If there are problems in the future, there will be less trouble, and those who are uncomfortable will be better off. It is preliminarily determined that the notebook to be purchased is N600, mainly in good color, and the merchant quoted 6000 yuan.

Pre-war preparation

After returning home, I began to prepare for the test flight tomorrow. Because the inspection of second-hand notebooks is much more complicated than the inspection of new ones, you should make full preparations in advance so as not to panic. After 1 hour's efforts, we prepared a USB flash drive, a CD-R (with data but not sealed), a D version CD (with operating system), an ordinary VCD CD, a DVD movie and a floppy disk, a network cable connecting two computers and a PC card. And prepared their own commonly used main application software and test software (including WinCPU ID detection CPU, Sisoft Sandra2004 detector, memory test software DocMem, Nokia screen test software, BatteryMark battery test software, keyboard test tool). The next thing is to have a good rest and wait for tomorrow's inspection.

Face to face confrontation

The next day, I went to the merchant's side. Since I was there yesterday, I simply chatted with the merchants and went straight to the N600 that I was optimistic about yesterday. Suddenly a N4 10C next to it caught my attention. From the appearance alone, it is no exaggeration to say that it is brand-new. Even the stickers on the machine are as good as ever, which makes me feel excited. I immediately asked JS that this machine was brought by a friend of JS yesterday afternoon. My friend JS just bought N4 10C, and met the company to equip them with machines, so this N4 10C has never been put at home. When you hear JS say this, change the target immediately. After all, N4 10C is a slim machine with a combined base. Of course, it can't be expressed in various ways at once. After cutting with JS, JS agreed to take away 6,000 RMB and gave a M300 battery. At the same time, JS also boasted that there was definitely nothing wrong with the machine. To find out what the hardware problem is, find one that is less than 100, including bad points and scratches. When I heard that JS was so kind, I felt something was wrong. After all, the current market is hard to say, there are too many JS. But since we said hello, let's look at the machine first.

Let JS take out the mainframe and all accessories (including CD-ROM drive, power supply, battery and base). First of all, of course, we have to test the appearance. Now the laptop sold by JS will be repainted or polished if the shell is seriously worn, but no matter how JS handles it, the appearance of the whole machine will always make people feel awkward, because the reflective visual effect and feel are far less good than those of the original factory, so it feels a bit strange, but the machine I chose does not have this problem, and the visual and feel are excellent, so it can be judged that JS has not been polished. Then carefully check whether there are hanging flowers and cracks in the fuselage, and whether the screws in various places have been removed, replaced or even missing. The most likely places to hang flowers are the bottom of the machine, the front end of the top cover and the wrist rest. As long as the place where flowers are hung is within your acceptable range, there is no need to be picky Of course, this should be written down as a basis for discussing the price with JS. If a cracked machine is found, no matter how small the crack is, it must not be taken. Because the crack represents that the machine has been dropped or strongly squeezed, it is difficult to say whether there is any internal hardware damage.

For the screws in various places, most machines will open them for inspection when JS buys them, so it is basically impossible to open them, but you should know that the screws in the original factory have been treated in various ways, and some of them are special screws, so they must not be replaced. The original screws are coated and closely combined with the machine. As long as you are careful, you can tell. I don't know if what JS said just now is true, but the fuselage is really good, and there are no traces of screws being disassembled. I carefully checked the LOGO on the top cover n times, and finally found a dot of 0.5*0.5MM, and JS actually called his friend with a face of disbelief. Finally, I learned that the trace was hit by a key when my friend used it for the first time 1 time, hehe, it was 100 RMB less.

I opened and closed the screen several times at will, and the screen was slightly tight during the flipping process. Of course, if it is really a new machine, this problem is also reasonable. As long as the screen doesn't feel loose obviously, if it feels loose, it means that the screen axis is badly worn and the screen may not be positioned where you want. At the same time, the screen cable will be loose because of this influence, which will eventually affect the screen display. Of course, you can't buy such a notebook. When you open the screen, you should also check whether the hook on the screen is intact and convenient to use. If the hook is not in good condition, the screen of the laptop may not close tightly. For the second-hand notebook computer with double hooks and single switch, we must pay attention to the problem that the two hooks are not synchronized. After opening the screen, I tried to knock on the keyboard and use the mouse board, which was very comfortable. The falling and bouncing of each key makes it very crisp and has no sticky feeling. Hold down the mouse touchpad with a little force and rub it in all directions, and the touchpad shows no signs of loosening.

Next, it's time to check all interfaces. First, check whether the PC card empty slot and the removable storage filling empty slot, the port replicator baffle at the bottom of the fuselage and the port cover plate are in good condition and can work normally. Without these little things, although the machine is not beautiful enough, it will not affect the use, but it can also be used as the price of black JS. Insert the PC card and USB flash drive prepared in advance into the interface to see if they are normal. If it is hard, it means that the bracket inside has been deformed. See if the interface pins of the network card and modem are in good condition. Also observe whether the interface of the power adapter matches the host jack. If there is an extra section or it is loose after insertion, the power adapter is definitely not original. Although this is not necessarily a big problem, poor contact is always annoying and harmful to the machine. Also look at the anti-theft lock on the laptop. If it is damaged here, it is basically black goods.

Finally, check other accessories to see if the nominal specifications on the power adapter are the same as those on the host, especially the voltage must be the same, otherwise the host will be burned out. If the current is different, it is acceptable for the adapter to have a slightly larger current than the host, but it is not needed if it is smaller than the host, which may lead to too long charging time or insufficient battery power, and may also lead to insufficient power supply when the host runs under high load and damage the host. Ensure that the power adapter is 1 10~240V, otherwise the adapter like 1 10V will be burned or even damaged in an instant. Carefully check whether there are glue injection marks and uneven gaps at the battery parting. If so, the battery has been disassembled and repaired. Check the base, try to install the machine on the base before ejecting, and observe whether the ejecting lever is stable and powerful. If not, first consider whether the machine can be easily detached from the base. After some inspection, it was found that the machine was indeed as JS said. If I wasn't picky, it would be a new machine. It seems that I am really lucky today, but I am not happy yet. Because if the above steps pass the test, only a well-maintained machine with good color can be found initially, but a machine with no problem in appearance does not mean that there is no problem in operation, and it must be turned on and logged into the system to check.

Take care of the bottom of the pot-prevent weakness

Boot into the BIOS system, of course, first hold down the pause button to see the basic configuration. Piii-m 1.2ghz/830mp, 256M memory, 40G hard disk, ATI radeon Monilitity/16m. That's right, N4 10C. The method of entering BIOS varies from machine to machine. The most commonly used ones are F2, DEL and ESC. Generally, the login method and BIOS version number will be displayed at the bottom of the screen when booting. After entering the BIOS, the most important thing is to see that the serial number is the same as the serial number on the fuselage. If it's different, nine times out of ten it's an assembler. You can also see whether the machine has a password. If so, be sure to ask JS for it. If JS doesn't know the password, be careful about the source of the machine. Of course, after reading the BIOS, I started the normal operating system. I estimated the time from the self-check to the completion of the system startup. Soon, the machine was normal. If it is found that the machine takes a long time to start the system completely at this time, it is likely that there are some hardware problems in the machine.

After logging in to the system, because the machine I saw was the operating system of WIN XP PRO, I first selected the control panel-User Account to check whether the logged-in user was the Administrator group. Don't think it's unnecessary, because users who don't have the administrator group will bring a lot of trouble to use the machine in the future, and if JS doesn't know the login password of the administrator group, it can be determined that the machine is black goods. Next, open the device manager and expand each branch to see if all the hardware is installed correctly. If there is a yellow question mark or exclamation mark, it means that the driver of this machine has not been completely installed and some accessories cannot be used. At this time, JS must provide. Insert the USB flash drive to see if it can be recognized correctly.

Insert the prepared CD-ROM drive and floppy disk, observe the working conditions of the CD-ROM drive and floppy disk drive, and see if reading the disk is smooth. If the floppy drive of the optical drive takes a long time to read, it means that the optical head and magnetic head are aging, and it is best not to buy them. Try to copy large CDs to the hard disk, and copy them several times if time permits, because some CDs can't be recognized when they are hot. If it is a DVD drive, try to play and read DVD and CD-ROM, and don't be afraid of trouble. Many DVD drives of second-hand mobile phones can only recognize DVDs, but not CD-ROMs. Since the CD-ROM drive is two-in-one and has the burning function, take out the unopened CD prepared in front and try to burn it. Both the CD-ROM drive and floppy drive work normally, but the wind is quite strong when the CD-ROM drive works.

I haven't used an external power supply for a while, mainly because I want to simply test the approximate working time of the battery, because the battery must try to charge. Before plugging in the power adapter, look at the logo on the nameplate at the bottom of the machine and the logo on the back of the power adapter, mainly to see whether the voltage and current specifications are consistent with the host, and also to see whether the brand model of the power adapter is consistent with the brand model of the host. Even if it is an OEM, there must be a line of small logo suitable for a certain brand product XX model. If the battery charge is higher than 90%, it may not be charged, but just now the battery has been placed below 90%, the battery has been automatically charged, and the display light on the host computer is also on. If you find that the battery can't be charged at all, it means that there is something wrong with the battery, power adapter or charging circuit, and you can't buy this computer. What's the difference between a laptop computer that can't use batteries and a desktop computer? Start timing after booting into the system, and then see how the battery is consumed. Nobody wants to buy a machine with such a short battery life.

Install a few commonly used software (preferably OFFICE, PHOTOSHOP and other large-scale software) and use it casually to see if it is normal and smooth. Use Nokia screen test software to change the screen background to solid color, then gently shake the screen back and forth and pat the top cover to carefully observe whether there is a flower screen or a large flicker on the screen. If there is, it means that there is something wrong with the screen line of this machine, and the screen may not work. Pay special attention to whether there are bright lines running through the screen vertically or horizontally. If there is, there is something wrong with the screen line. Then check whether there are any bad spots on the screen. The machine with bad spots really feels uncomfortable. Then I adjust the screen to full white, adjust the brightness contrast to the maximum, and step back to see if there is uneven brightness on the white screen, paying special attention to the corners and bottom/right side of the screen, because usually the lights are installed in these two positions. Generally speaking, the screen performance of second-hand machines is not as good as that of brand-new machines, and the screen will turn yellow, as long as you can accept it. If the screen has color cast or color spots, you must never buy it. It's the screen itself or the screen line, and some may be the graphics card.

Now I have begun to believe in JS, because the color, contrast and brightness of the screen are perfect. Open the control panel, select the options of sound and audio equipment, try to play the sound, and try to play the sound continuously, and adjust the volume repeatedly at the same time, feel whether the sound plays smoothly when adjusting the volume, and listen carefully to the sound box for noise. If the volume is broken when there is still a lot of room to reach the maximum volume, it means that there is something wrong with the speaker of the machine and it may have been injured. I asked JS for a pair of headphones and a MIC. I mainly use it to see if the external sound interface of the notebook is normal. Under normal circumstances, the sound output by headphones should not be very noisy. If the sound just appears too fast or too slow, it is generally that the sound card driver is not installed correctly. Open WORD, enter a paragraph of text at will, ensure that the mouse and keyboard can be used normally and correctly, and use all the keys on the keyboard once with a little patience, including key combination. If you go back, you will find that there is something wrong with the mouse and keyboard, and JS probably won't recognize it.

The final battle test

Now I am satisfied with the initial use of the machine, and I am ready to test the machine with other testing software. I don't need to say more about the next test. The use of the software is very simple, but you must pay attention to whether you can change the machine if you find problems during the test.

After running the test software with me, I asked JS for the SUPER ∏ program to run. According to the habit of using computers, as long as I can run this program normally, I can basically prove that there is no problem with the host. Finally, the detection of hard disk tracks, the easiest way is to run ScanDisk to see, each partition should be detected, the purpose is to eliminate the possibility of bad tracks, if you see those machines whose shells have been knocked off, you should be especially careful. See if the machine you choose has wireless network card and Bluetooth function. If you have a wireless network card, be sure to find out the type of the network card, and be sure to see the hardware of the wireless network card under the network card of the device manager. Some machines only have built-in wireless network card antenna and switch, and there is no card in the machine. Don't be fooled by JS, and if there is a card, there will be an indicator light after opening it or a connection indication in the lower right corner of the taskbar. These are the basis of judgment. You need to install your own wireless network card to buy this machine, but JS is very authentic. Tell me there is no card.

Now the inspection can basically come to an end. Finally, listen to the sound of the fan. If there is a sharp sound when the fan is running, it means that the fan bearing is worn. If there is no sound at all, it means that the fan is not running. Restart the machine, because most laptops should check the fan when they check the BIOS. The fan will turn for a few seconds, so long as it can turn, it will be fine. If there is no fan sound all the time, make sure that the selected model is air-cooled, indicating that there is something wrong with the machine fan.

Harvest the fruits of war

After the above tests, the notebooks that can pass all the tests are basically reassuring. Next, I will use my eloquence to bargain with JS for the problems found in the test. Just now, a small flaw in the fuselage forced JS to give in 100 RMB. Finally, the payer asks JS for the invoice. In order to avoid future troubles, JS is also required to write clearly the model, configuration, purchase time and warranty time of the purchased machine on the invoice. Then immediately charge the machine in JS's shop, format the machine (preferably repartition) and install the system, driver and required software to ensure that the machine can be used normally. This can also make JS speechless when encountering problems.

Second-hand gold panning is definitely a combination of risk and quality. Whether you can pick the best products depends not only on your eyesight but also on your luck. It is even more difficult to buy a good machine at a good price. Here, I introduce the process, usage and some experience of buying second-hand notebook computers. Of course, I should say that my luck is still quite good, and then I can only wish you good luck. Be sure to remember to be bold and cautious when buying and keep calm.
