IBM's books have been well received by people like a notebook. The time of purchase, for the average user how to select books to a genuine buyer will be the biggest wish. Here are the books I used in the purchase of IBM, when finishing the document, hoping to buy some reference to the black family friend.
1, the true distinction between mainstream
Three main flow of the market: mainstream, parallel imports, code Unit
Licensed:
A, each have a genuine IBM laptop in the club membership card, and has been marked in the packing list, packing list, if not, then packing list is fake.
B, each in a genuine IBM Thinkpad ThinkPad notebooks are the only 7-bit product number, product number code top four for the notebook series, such as 2672, says that the ibm-thinkpad-r60-battery. After the three models per a specific model, the last one represents the target sales, the sales of the licensed in mainland China are based on capital letters "C" to the end, "C" on behalf of "China". "H" Hong Kong, China, "U" for the United States.
Market selling ibm-thinkpad-r40-battery, CC0 and BC0 are also licensed, but they are the number "0" (many people think is the letter O) as the end.
C, there is a warranty on the wire, printing processes have obvious sense. The distinct impression that the printing of writing a concavity above, there is a warranty on the right vertical wire looming, as the warranty had said, it's similar to paper money printed by the printing technology. This is also the focus of the user should pay attention to, if warranty is not these two features, then this machine will have problems.
D, IBM Users Club Manual is a machine one, can not fake, they must be recognized it must be code number or machine. , Because this manual have a unique verification code IBM club members, allowing only registered once, so agents detained the general will not dare to sell it, which is an important characteristic to identify whether licensed.
E, IBM notebook bottom of the fuselage has a Microsoft operating system label to the color to distinguish the different languages, Simplified Chinese version is orange, if it is other colors, the product code number is certainly machine.
F, but also on the warranty card, the body of the COA codes and other machine information for query validation, in particular, are printed on the bottom of the COA code orange, and if these codes are correct, and basically no problem.
G, IBM laptop's serial number label on the bottom, arranged in order of "machine model - number - date of production, such as TYPE :2652-3BC S / N: 99XGA-22 0802" production date related to the machine warranty
Into the computer's BIOS we can find the serial number (System-unit serial number), check with the bottom of the label to see whether the two numbers match.
System, named "thinkpad configuration" of the software can check in "system imformation-Bios imformation in a machine type-model is. BIOS serial number in the most reliable, because there is no means to change the BIOS information on the cost. If the check serial number on the label does not match, then 90% of the laptop repair, refurbished machines.
IBM notebook comes with a ibm-thinkpad-t43-battery control program in here the user can check the battery usage and monitoring, including: serial number, capacity, performance information, the current frequency of use and so on. Through this program can get very accurate information.
"Cycle Count" is the charge of a number of times, as well as "First User Date" the date of first use the battery(ibm-thinkpad-x40-battery). This information can be reflected from the side, whether the new laptop.
IBM's services can call the hotline 800-810-1818, by serial number to obtain the exact product warranty time.
Parallel:
The same configuration, but in non-China regional sales models, these products are smuggled to mainland China sales, to be known parallel.
Unit Code:
Unit codes are generally from the same configuration, but in non-China regional sales models (these products are smuggled to mainland China sales, to be known parallel) converted, and some industry participants have also called it " Brush Unit. "
IBM genuine laptop accessories
How to identify IBM power adapter
Observe the brand logo. IBM power adapter all have "IBM" the three-color logo, the color of the three letters were pure red, green and blue. By comparison, the original adapter of "I" dark and fake the "I" to be red than some of the real thing; fake letter on the "B" and "M" in the color of light than the real thing a lot, that is, color cast is very serious, especially the letter "M" is obvious. If the purchase did not take the real thing for comparison, you can put the power adapter "IBM" logo and the IBM notebook computer cover of the "IBM" logo Comparison
Shell color and technology. Original shell of the adapter was dark color, darker in color, while fakes are black color though, but obviously partial gray; genuine addition to the housing area outside stripes are relatively smooth, and obviously fake grainy, hand- can feel it.
The bottom of the sticker. These fake stickers on the bottom of the adapter origin marked as "Astec Shenzhen, China manufacturing," although the text on the stickers printed with the real thing, like a very clear, but the fake text was pure white, while the real thing is white, and therefore looks dim some, this is particularly evident in the vicinity of bar code.
The difference between the power cord socket. Parts of the power cord plug adapter, so there are obvious differences between fake. Genuine outlet around the box was shaped plastic material and other parts of the shell color and consistent, while the fake is a very big difference, obviously fake plastic around the left due to poor workmanship burr.
Check IBM books Masachika:
1, View S / N code.
IBM laptop's serial number label on the bottom, arranged in order of "machine model - number - date of production, such as TYPE :2652-3BC S / N: 99XGA-22 0802" production date related to the machine warranty
2, check the BIOS, the serial number box and the fuselage
Specific steps are as follows: Without the case of external power plug boot, in the event IBM LOGO while holding down the F1 key to find the page that appears in the S / N this one, its and boxes of the S / N compared to No. to see if it fit, if consistent, can exit the BIOS, the body, in turn, found the back of the bar code label to see whether the serial number above on the same box, if you can fit into the system. In general, parallel machines are already unpacked (WIN XP can not be registered to the system), which can enter the corresponding operating system, which is due to cross the border from Hong Kong to take the time to prevent the machine made under the detained some measures, if this is the case, then just click Start, select Programs option in the ThinkPad Utilities, click the console application, which in the last page also has S / N number, will be to compare him and look at the box is consistent, if all of these items is no problem, OK, that machine as a whole is not much of a problem. Not solvable if the system package, then unpack the first to conduct the above process, it is very important, not because the system did not unpack to skip this step, it is not desirable. This step can be completed the next step.
3, rechargeable battery <ibm-thinkpad-t42-battery >
IBM and the industry is only able to directly see the SONY laptop battery charge, which is to provide users with a lot of convenience, and we tell whether the machine can be used be a very good way to see the number of charging methods as follows: Click Start, select Programs option in the ThinkPad Utilities, select BATTERY INFORMATION, click Stutas Detail page, where the Cycle Count is the number of charging this battery(toshiba-pa3399u-2brs-battery), in general, the number of licensed battery 0-1 times in between, if more than this number may be a problem, generally parallel, then not more than three, otherwise there may be problems if the number in the dozens of charge, then do not look to see, this machine have a problem
4, check the warranty date
IBM's machines generally come with 1 year warranty to 3 years and this is the user's convenience at ibm-thinkpad-t60-battery, but also when the machine picked a very important step, the specific method to the following URL
http://www-3.ibm.com/pc/support / site.wss / warranty / warranty.vm, in the open page, enter the serial number on the box, you can, you'll see this machine Sales countries (should indicate if sold in mainstream China), as well as the machine's warranty expiration date, and machine quilt machine manufacture date comparison, to see if there are problems, there is no problem to be offline for the next step .
5, eyes that check dead pixels
Specific steps are as follows: If you have not done any preparation, no special software to test it, can be achieved with the naked eye but also the effects of selection, first delete all the shortcuts on the desktop icon, right-click the desktop, select Properties, in the background options, select the picture is none, then the color in the lower right corner to select a variety of colors, mainly red and black and green to choose the Fifth, each switch to a color to carefully look at the screen with the naked eye there is no and display color different points, there is no, then switched to another color, until the end of all the colors look. If you have prepared a special software, such as NOKIA screen test program, you can directly put to the test run, the effect is the same. If the number of tests have found no dead pixels, then congratulations, you compare the screen perfectly.
6, other
Use a screwdriver to open the hard drive and memory ****s to see if there are two parts of the private label and IBM FRU number
