This is now the largest number of second-hand market, a way inside. A large number of foreign garbage is put into containers and shipped to China's coastal cities, where, not by how many come on the price, is based on a number of former container, the number of prices before the meal count. Then again, these retailers are looking for can be repaired from the inside, or you can continue to use the machine out. Now a lot of second-hand laptop also comes through this channel . Because it is foreign garbage, a lot of machines are impossible, but not all are broken, the business will be dismantling their own parts, assembled into a laptop computer, through various channels into the secondary market to sell around. Market selling T20 / 21/22 X20/21 almost all comes out of this.
1, the foreign garbage
Europe and America pay attention to bold notebook factions are not normally very small, and many more 12,13,14,15 majority. 14 and 12, which is common.


Notebook tricky, many second-hand market, a variety of machines are different fineness of the machine conditions, which to buy used laptop computers have brought no small difficulty.
Second, the new low-end of the hand or the
In addition there are a few of the T30 series of so-called T31 models, such models is ZF custom machine, in addition to other models, all the same, and T30. Specific parameters refer to the above article.

As in Taiwan, the Taiwan notebook manufacturers is also a gathering place, famous have ASUS / ACER / WINBOOK so few of these notebooks to see in the secondary market, among which the largest number of WINBOOK and ASUS. These notebooks designed the golden mean, not like Europe and America professional, not as Fashion. Than the domestic price of slightly more expensive second-hand laptop, but the Department of Europe and America than in Japan and South Korea, Department also lower.

1, European and American factions

Japan's notebook industry is quite amazing, well-known are: SONY / Toshiba / Panasonic / SHARP / Fujitsu, Japanese most compact notebook, always giving a visual impact. SONY SRX in particular the series and the C1 series, is the leader in the ranks thin and light notebooks. Destruction of the boys and girls is a huge, often people \ Need careful consideration before buying.

First look at second-hand laptop screen. Screen expensive, almost a second-hand price of 3 laptop computers, is one of the most people buying a laptop, a part of the need to pay attention. LCD screen is white the most taboo. After such white notebook mostly caused by high compressive strength. The feature is a white, there is a very bright white areas. In the case of full-screen black, black color is also lighter. Laptops are generally white, I do not recommend buying for several reasons: 1, such laptop screen ineffective; 2, resulting in white spots is mainly due to compression, so that the laptop must be dropped, or received of other physical impact. This notebook is a hidden danger. 3, to consider the preservation of view, a white spot changed hands again, the machine is not easy, but also significantly lower than the spot price of the machine similar models.


Third is the bright and dead pixels, and dark spots. The so-called dead pixel, that is, within a display pixel, has been shown white. Dead pixels are within a certain pixel has a color display; dark point is the point in a pixel, the total displayed gray. Which the destructive, the highlight of most people a headache, there are dark spots or dead pixels are acceptable, after all, the new LCD monitors can not guarantee absolutely no dead pixels / dark spots. But there are bright spots on the screen can not be accepted, after all, is very harsh. Users feel uncomfortable.
Screen brightness, and color uniformity:
X3 series is a classic series, although I love or X22, but the first has a shock to me when X31 is still not small. X31 is the standard size, weight, during which the 12-inch body fat middle, it looks pretty thick , and even T4X as thick as the ... ... However, this did not affect the X3X classic status. X30 all the communication functions to create the first all-X models, X31 is called first-generation Centrino platform, the most classic 12-inch notebook. X31 X30 a change in the controversial integrated graphics, graphics card onto the road. X31 has long battery time, hang up the second battery, can adhere to the more 10-hour power supply. And X31 will support 2631dock , a lot of black friends to save money, has become hot in the secondary market X31 reasons. X32 small number of second-hand, but not worth buying just for the CPU after the X31 product performance is not, which can be placed in disregard of the position. Buy X31 note whether the main pieces of broken plastic case, but the hand in the case of X31, it is likely to cause fracture care palm.



There are basically second-hand laptop bought the following categories of people:

Nowadays, many domestic manufacturers name: \ The new notebook. Part of the old-line manufacturers are forced into a price war, launched a number of 5999 the price of notebook computers. For example, HP / COMPAQ's M2010AP, IBM R50E and so on .
T30 is a favorite author T series Thinkpad, especially the Mexican version of No touchpad T30, is the author's favorite! T30 on the topic someone always says how bad. In fact, under special circumstances T30 is a good machine! In the P4 high fever , high-power era. T30 with the latest cooling system. On the corner of the cooling system, increasing the cooling area, the wind area. This is an innovation! Now look at anti-T60, also is taking the same road, on the corner of the fan, indicating that the T30's superior design. Although T30 thick body, but also to ensure its superior heat dissipation. SONY R505MCP the P4 model is small and yet because of lack of cooling capacity is very likely to crash. T30 body is so thick you can tolerate. And the IBM T30 is the first use of ATI graphics card T-series notebooks and changed the situation of T has always been the weak graphics card, graphics performance on the first time beyond the X, also set a T high-performance banner. IBM T30 Model 7500 is 16M, and 32M models have some performance differences should be noted. The only caveat to buy T30 is the problem of memory slots slot, is said to be caused by such problems as the bezel. In general, the later success of T30 have solved the problem, problems are early T30. Try to buy carefully. Problems unlikely.
2, the drive is easy to use: 9,5 mm of silm drive to bring the light and portable, but the problem comes, he too durable it! Widely with the COMBO T40/41/42 often do not recognize disk drive, DVD function failure, not the normal burning and other issues. What needs attention.






Some people say that X3 X4 is the successor product, it is not. X4 is S series of successors should take the slim line, X31 is a portable and efficient representative. Two different routes, and in time merged into X60 and X6 X60S. X4 X40 series the most vulnerable in the secondary market for people to accept. But I believe that prices are generally higher X4, X41 actually be sold for a price close to 1W, you know, X60 is nothing but succeed only 1W! X41T as IBM's first real table PC, more successful, but the shortcoming is the use of a 1.8-inch hard drive, impact speed. Other parts, for the first time for the IBM Table PC, it can be \ This situation resulted in high prices X41T.
These IBM laptop, belonging to T series of scaled-down. R30 with copper core P3 / Celeron, R31 with Tualatin core P3 / Celeron, R32/R40E / part R40 is used P4-M / Celeron 4-M as the kernel. High with a small amount of R40 with Centrino architecture. As R30/31/32, I do not suggest that you choose. I think that is IBM R Series R30/31/32 inside the flaw. These types of laptop motherboard is extremely easy to damage, usually performance is: can not find the drive. Or start difficult. But to the R40, the internal structure will have a drastic change. First, R40 launched Centrino architecture models, across the board with U2K Interface (R30/31/32 for the fixed optical drive), provides a USB 2.0 interface, 1394 interface, and overall quality improved. And high with the R40 Centrino IBM because it is the only interface to an integrated U2K / 1394/USB2.0 the IBM Centrino machine. The interface of its own U2K alone this one, let a lot of IBM fans sought after. For example, IBM unofficial Network: specialized nets two administrators (HOPE / guy) is a person with a R40. But R40 Centrino version is divided into two types of M6 graphics, 16M memory. One is the 7500 graphics card, 32M was inches. One more video memory 32M purchase value. Recently appeared on the market a number of 15-inch R40, R40 almost all of these assembled goods, purchase of necessary caution. Besides R40E, R40E is R40's shrunk version: USB 1.1, CD-ROM is not accessible, integrated graphics ATI motherboard, mono, no video output. No touchpad. Personally think that these machines is not worth buying. Not much point, R40E laptop has lost the essence of some of IBM, not vote worth mentioning.


Read the LCD, and then to check is the whole appearance. Appearance General points: the top cover, screen baskets, care palm, keyboard, bottom shell, all kinds of cover and so on. Cover and supporting the palm is the renovation of part of the business favorite. Identify a number of roof renovation tips: renovated roof, most do not LOGO, or some local defect, lack of paint can be seen within the second layer, then this is a refurbished roof. As for IBM notebook computers to more easily identify the (for T20/X20 later machines), is to see out of the depression level of LOGO. No refurbished IBM laptop cover surface coating and a certain gap between LOGO and LOGO above have a special coating. If renovated, or cover the surface of LOGO and see no gap between the coating and very smooth LOGO, lost the protection of the coating.

Faced with such a price, many people on the heart, the 3999 and most of the prices have been used in the end, like a laptop computer prices. For example, T23 (there will be described later), a typical secondary market prices in 3700 or so, and these cheap new notebook computers only difference of about 300 round, no wonder many consumers attracted to these low-cost notebooks.

Famous COMPAQEVO series, just as IBM T series, as are all business as the main direction of the notebook computer. Previous EVO notebook is similar for the IBM T series models available. The same quality, same performance equal shares in the new machines on the market. And by the secondary market as well.
2, in good enough psychological, and large sums of money to save the people
3, T41 and identify T42: T41 and T42 was said in the 14-inch models support the major difference is whether the power-saving valve function. In actual fact, I bought a T42 motherboard do not have this feature, but its support for fingerprint identification, will no doubt for the T42 board. In fact, IBM T41 and T42 in the definition of the main criteria is defined as the main CPU. T42 common core with DOTHAN PM processor, T41 is the old core. There are differences in L2 capacity. DOTHAN as long as the U, even the T41 rose up, and I think it can be considered a T42. If you have to define so seriously T41 and T42, only through the board to determine the number and body number was.

With this kind of psychology is the representative of pragmatism, 3 to 5 years ago to deal with a laptop program is now generally more than sufficient, and even some models (such as IBM A30P), or a lot of friends to do the first choice for 3D video processing. If you just Internet access, typing, chatting, listening to music, about a 3000 second-hand laptop computer and a twenty-three million new high-end laptop round for you, there is no difference, so they used the best laptop computers choice.


But we look carefully, in fact, these so-called low-cost low-cost laptop is mixed. The new second-hand laptop looks brand new, in fact, know a little bit to the computer's friends only, Blue notebook which uses VIA C3 CPU, although the frequency has 1G, but the actual performance is low, in actual use, and can only INTEL P3 800 and a tie, VIA C3 in multimedia not as good as or even P3 750. 128M memory with WINDOWS XP in this era of the mainstream, too little, right? And such notebooks, most work in general, extensive use of desktop computer accessories, strictly speaking, you can put them as: install a battery of mobile PC. However, he finally is a new machine Well, repair, or more than second-hand laptop good terms, but benevolent see benevolence and the wise see wisdom. Low-cost high-end notebook and laptop takes better second-hand, or your own decision. Operating System
IBM X22 has been hailed as users: most valuable second-hand light inside of a laptop. Indeed, X22 IBM X Series notebook as a turning point in the development of IBM X series has a different meaning. X22 in the tradition of the elders on the basis of the appearance of X20/21. Construction on the house carried out a bold reform: use Tualatin core P3-M Low Voltage CPU, the strong performance of the ATI M6 8M graphics cards, as well as on the X22 provides the first 1394 / IR / Wireless LAN (WIFI / WLAN) in features that allow then to have eclipsed the mainstream T23. X22 with the ATI M6 graphics card is T23's S3 graphics cards to shame. Today, play CS 1.6 with the X22 is very smooth. And X22 with improved 6-cell battery, capable of X22 provides 3 and a half hours of electricity. 2631 with the expansion of IBM's unique tungsten. Let X22 has a PCI, U2K drives and other expansion. There are even users, through the modified pieces, so that X22 spend the success of a 3.5-inch hard drive. So far, X22 is still the first choice for many enthusiasts. The IBM X23 is the X22 to further improve the frequency, so frequency reached 866. And installed in some models of the Bluetooth adapter. But X22/23/24 have a common drawback: Bluetooth, WIFI, LAN can not be built on the same machine inside. One has to give one. However, netizens, or found a solution: a USB Bluetooth adapter shell removed. Welded to the laptop inside, and then under the antenna to the keyboard layout so that we can realize the function of the Bluetooth built-in!






LCD screen displays the unique way the color more or less have some distortion. Most of the limited single-tube design notebook computers to the situation there will be uneven color: black performance in the case, the bottom of the screen brighter. Generally not very bright, or there is a clear bright line, is in the acceptable range. The screen brightness is a relatively subjective side. In general, not yellow, red, then basically you can.

Second-hand laptop on the market today, the largest number and most common is IBMT20/21/22/23. Such models belong to the copper core of the P3 model, the model is not too old, used the Internet, word processing, music and so more than enough. And relying on IBM's flagship, as well as good quality and price, basically took half of second-hand notebook market. 14-inch size T20/21/22 are equipped with U2K interface drive. Such a large drive optional, low cost, but also provided a large number of the original field from the IBM conversion parts. After the upgrade to T20/21/22/23 provides a lot of space. And whether it is T20/21/22/23 , most of its components are interoperable. Some of the enhancements are backward compatible. For example, palm care, keyboard. Roof, etc., are common. The radiator, it is backward compatible. This also caused the price of T20/21 / 22/23 low maintenance and easy to maintain. This also allows a single assembly machine can spread in the market. Now I walk around in the secondary market, it is difficult to see a true original, and not refurbished T20/21/22 / 23, most machines are refurbished. Cover, prop traders refurbished palm is a favorite. Because these components are very intuitive. Will directly affect consumer judgments. The renovation cost and very low (an X20 roof renovation, only 10 ~ 20), and refurbished as a Condition good machine to sell, the price difference is usually 50 to 100. And in the secondary market now are from Guangzhou T20/21/22/23 businesses into the goods side, many goods in Guangzhou, there has been refurbished. However , most of these machines using IBM's original parts to be assembled, if the test is no problem, or you can buy the. The T20/21/22/23 T23 when the number of the most famous, and after a series following the TP600 , IBM is another successful works. By T20/21/22 appearance, which was the most powerful use of the Tualatin core P3 CPU, and provide the first equipped with a wireless network card T23. And provide for such a special form of T23 antenna ?? On both sides of the antenna placed on the screen, let it get better signal. The T23's U2K interface, but also provide CD-ROM/DVD-ROM/COMBO/DVD-RW / second battery / second hard disk (support boot ) / Floppy / ZIP drive / second digital keyboard / PDA synchronization frame and so on. Top () interface can also add camera and infrared adapter. Powerful functions, extensions of the rich, enough to shame any laptop now on the market.

T4 Series points four times, each period has two different positioning. Are T40, T41, T42, T43. One T40P, T41P.T42P.T43P and delineated in the different models of non-P position. Models with P located in the high- end graphics workstations. And high-precision mapping of the area,[link widoczny dla zalogowanych], T40P, and T41P with a 14-inch SXGA + screen. T42P starting from the emergence of 15-inch T42P, and later T43P. While 14-inch T42P and T43P still a sell. But 15-inch UXGA T42P and T43P all the IPS screen, manufactured by the ID. In addition to screen differences, P and non-P biggest difference is the use of graphics. Selected with the P model is ATI's professional graphics. T40P which is used as the core 9000 FIRE GL 9000, its version of the same kernel and T40 high marks, but memory expansion to 64M, and the memory bandwidth is also extended to 128bit, performance than the 9000 core to enhance the larger T40. T41P and T42P is equipped FIRE GL T2, this core is ATI R9600-based evolved. Performance is more powerful. T43 X600-based development is based on the V5200 from the core. All of its graphics cards with P's T4X/R5X entertainment properties are close to the core of which it is based. R50P is the only one on behalf of the R5 series of P inside the model, R52 has been removed R52P this model. T42P R50P like a plastic case version. R50P part of the fan with a long tube, some use the heat sink. And R50P in the first time, QXGA resolution IPS screen, which is 15-inch screen has the highest resolution. 51nb forum many users have DIY T42P/T43P based on this screen out.

EVO N600C and the T23 is basically the same configuration, the main difference is that the graphics card, N600C is the ATI M616M/32M graphics, a lot of graphics performance than T23 S3. And N600C screen models also provide high score, and the effect of the screen than the T23's original farm well. However, the expansion of T23 and software of the rich is the N600C can not compare. But it is worth mentioning that: N600C M700 super extended use of tungsten, which for the N600C worth more or less improved some. The N610C/N610V/N620C can not be used. M700 is basically the idea N6X0C framework, improved from. The most obvious feature is a pointing stick / touch pad dual mouse (later IBM R40/T30/T40/R50 have the same design), and increased the reign million extension, provision of Bluetooth, wireless and other functions. Black and silver and white cover, more a stylish atmosphere. The N610C/N620C step by step for the N600C is just an upgrade, but the internal structure has changed. COMPAQ already showing signs of fatigue that year, the replacement structure as a whole did not update the machine, and IBM, but chose to upgrade. Chosen to continue to use the way the original design, which also contributed to the N620C less success. The most interesting should be considered N410C, he, as P3-M architecture, 830PM motherboard. Has the same appearance and N6X0C, but it has USB 2.0 functionality. INTEL Southbridge does not support USB 2.0, COMPAQ N410C creative re- added to a USB controller provides a USB 2.0 function. The same design also appears in the COMPAQ N610C above. Many of my friends to the USB 2.0, gave IBM X24/T30.

IBM A Series has been targeted at mobile workstations, and later because the volume is too large, instead of by the R50P its location, but the A30P and A31P are still very classic Thinkpad. A3X biggest feature is its use of models with P,[link widoczny dla zalogowanych], the IPS screen, and provides two U2K interface, can link two U2K equipment (batteries can only pick one), which brought great for users convenience, in the era of abundant IBM U2K equipment, A31P +2631 U2K a total of 3 slots available,[link widoczny dla zalogowanych], allowing users to magnify the efficiency. Both A30P and A31P possess the necessary professional graphics capabilities, but also a low-cost mobile workstation. Where the graphics core is based on the A31P Ray 7500 FIRE GL 7800 graphics card.
Used today is nothing more than 3 major factions in the notebook market:
These players are not poor, I've seen a lot of rich people to play second-hand laptop, bought a laptop only 5 thousand won, the results of peripherals, renovation, upgrading, tossed away nearly 3 thousand. Not the price they pay attention, pay attention to the \ Of course, there are many \

The IBM / COMPAQ / HP / DELL as the main force, while IBM is the main force of this team is absolutely the same, but also the absolute mainstream of the secondary market. Today the secondary market, Putian the earth, are IBM's LOGO. The HP / COMPAQ, there are many good machines, for example, comparable to the current year and IBM T2X killing the M700, N600C, and later challenge the N610C/N610V/N620C T30/T40, etc. Looking back now the machines are still people aftertaste.

Fourth, analysis of secondary market supply
Buy T4XP should be noted the following:
1, whether the assembly machine: Because T4X and R5X a large number of common parts into the market, resulting in a large number of assembly T40/41/42/43 was once the case, some original pieces by IBM, some pieces directly from the workshop in Shenzhen. Great differences in their quality. Buyers can go to IBM T43 store experience what it feels like the real, look at the upcoming purchase of T4X, if greater access to quality can be determined for the workshop machines.
SONY notebook has always been full of fashion, entertainment elements. SR / SRX models are similar, they all have 10-inch XGA screen, good scalability, mobile capabilities, so that in the secondary market before it sought after. The C1 is reached the limit, using the 8.9-inch widescreen display, and provides a camera. Let C1 be the most talked about second-hand market which a thin and light notebooks. However, because of scarce supply, its price is high, then up. A purity no problem, complete accessories, four generations of C1, the price can reach 5500.

Smuggled goods, commonly known as dirty cargo, namely through the stolen / robbed / cheated, etc. Get to the laptop. Such notebook has: Condition good, low price, configuration close to the main features. And such number of very small notebook. Most businesses can not outright on the counter sales. Usually by Identification of these notebook: whether there are pry marks locking / password, etc. if the machine identification. But I advise you, this machine is not cheap prices and then buy, do not trouble yourself to spend money, worth the ah!
4, smuggled goods
Condition is better most of these products, after all, individual users, to spend tens of thousands of pieces to buy things also, after all, care. The machine configuration generally close to the mainstream, with domestic-based, supplemented by imported models. Relatively high prices, and a small number of such machines. Most of these users is the home problems, and need money badly, or the purchase of a new laptop, so just deal with it. So these machines are also more comfortable buying them.

First, who needs hand laptop computer?
Received the title of BSET BUY M700, not only the year in the new machine market and IBM T20/21/22 kill the bitter, but to the secondary market is still outdone. The same strain M700 and M300, M300 M700 is like a smaller version of the same. M700/300 product line is longer, up to the P2 model, copper down to the P3 1G models. So models are more confusing. One key is to look at the mouse part of the M700, M700 a pointing stick and touchpad are two versions. Is essentially no difference was mainly a matter of personal likes. The M300 is mainly to see the size of the screen, P2 is the core of the M300 11-inch SVGA screen, while the P3 core of the M300 is 11.3/12.1 inch XGA screen. Like the mouse too, and M700, there are two. M700/300 roof strength is very high, even more than T20/21/22/23 titanium alloy. And the M700/M300 can also use a special extension COMPAQ tungsten, tungsten face of this expansion of well-known expansion of IBM, no less: 3 PCI / 2 5-inch bit / 2 3.5-inch digital / integrated 2-channel Speaker / with a display bracket. IBM, the TP600 is perhaps the only series to rival the expansion of tungsten to it! The only drawback is, however M700/300 software support too little, far more than IBM, which also resulted in M700 as in the case of battery capacity, use of time because there is no T20/21/22 a long time. In addition, M300 machine as small size, so the battery time is very short, the new battery is only 2 hours of use.

Secondary market inside the machine, different channels, so that the price of the same cause, different fineness, and other differences. The author summarizes the main channel of the second-hand laptop computers
These sources focused on DELL laptop. DELL unique marketing model because, sure he does not stock ideas. How many goods he handled it? Mostly handled by the price of 6 pack to internal employee. DELL goods or renovation, repair, after a very very low price deal to internal staff. Then resold to second-hand dealers of these employees. Eventually appear in the secondary market. General quality of these goods is guaranteed, even repairing the goods, but also DELL original field maintenance, the quality can be decent . The internal goods are the mainstream Centrino models, configuration of strong, and cost only half of the new machine is a very good value choice.

SONY R505 opened up an era, 12.1-inch screen, discrete graphics, 2Kg less than the weight, at that time is definitely a milestone. R505, a total of 5 generations: the first took the MMX core product, not worth buying; the second took the P2 core, the performance is too backward, nor should select enough. To the third generation of R505, put on a Tualatin core P31G CPU, use the same 16M M6 and X22/23/24 cards to ensure that the performance of the lead. Price is slightly higher than the X22/23/24, but stylish, the screen effect, is a good choice. Fourth-generation R505 core as the P4 era, this section R505 design defects, thermal solve well, laptops easily lead to crashes. Fifth-generation R505 R505 have inherited the appearance of the fourth generation, but the switch to Centrino architecture, this R505 is the most worthy of a purchase too. Price slightly higher than the price of IBM X31, but it contains COMBO drive , 9200 graphics card. This is the X31 can not match.
