But now the laptop and battery market, but charge a lot of times a refurbished laptop computer laptop battery , which we are talking about refurbished laptops, refers to the laptop and battery manufacturers or individuals will have been damaged or worn-out laptop and battery recovery and make the appropriate repairs and renovation, the re-enter the market to sell, because these laptop and batterys

In appearance and a new laptop and battery computer is almost the same, so it is easy for unscrupulous profiteers as a new laptop for sale, so that marketing costs have suffered, and these refurbished laptops whether in quality, performance and service with the The new laptop has a very different, and their serious harm to the interests of consumers, today we have to come and talk to you about how to identify refurbished laptop and battery computers.

Now on the market two broad categories of widespread renovation of laptop and battery computers, a large class is a factory refurbished laptop laptop and battery computers, and those by some underground factories turning on their own line of laptop and battery computers.

Let's take a look at from the factory refurbished M8403 laptop and battery computers refurbished laptop currently on the market of the original IBM-branded computers to be more common. As these laptop computers are refurbished by the original manufacturer after IBM into the market, so product quality and appearance are very close to the new laptop, so you can rest assured that the use of ordinary consumers. But this original rework machines are generally only a one-year warranty service, and prices cheaper than the brand-new laptop a lot, so if consumers do not care to treat it as a new laptop to buy back, is estimated that businesses will definitely be smiling at the news of the. In view of this fact, factory refurbished laptop, laptop and battery manufacturers in the renovation of laptop and battery, refurbished laptop in order to prevent confusion with the new laptop and disrupting the market, it has long left a mark in a laptop and battery, as long as our attention to the following places, you can easily identify the true knowledge of their hats.

First, we should pay attention to is the original renovation of the bottom of the M9324 laptop and battery will be marked with a "This product is refurbished and contains used parts" of a small label (meaning that: This product has been renovated and includes used parts), shown in Figure 1 shows, the left is a refurbished laptop computers at the bottom of the red circle shall be marked for rework of small labels and the right for a brand new laptop, the above is not such a small label, the following the label for the amplification part, this is to identify the original IBM laptop repairing a very important symbol, of course, that some cunning businessmen will probably tear up this label, but the label even tear up, he will leave in a laptop and battery the corresponding traces, so if we choose laptop and battery found similar traces of the bottom of which we are completely justified in refusing to accept the laptop, because the new laptop is not likely to leave such traces.

Another important identity is the insert in Figure 2 shows, in the specification of repairing laptop and batterys, there are also a similar mark on the left is the repairing A1185 laptop and battery computers brochures, on the cover of the instructions on the rework, while the right is the full The new laptop and battery computer manuals, cover the absence of such instructions, the following instructions to amplify part of, please note that circled several places above clearly indicate the laptop and battery containing used parts, and warranty period of one year . Also in the laptop and battery has a similar mark on the box label, so we choose laptop and batterys do not forget to check this when a few places, if found such labels, proof that the laptop and battery as a rework machine.

The above mentioned factory refurbished laptop because of its fairly good quality, relatively speaking, so the harm to consumers is still relatively small, but another entirely by the underground workshop where some of the refurbished A1175 laptop and battery computers, and their quality can be completely no guarantee. Because it is their own business renovation, now is posing as a new laptop for sale, of course, will not leave marks in a laptop and battery, so the method mentioned above have no effect against such laptop and batterys, but we can follow the following approach to identify the :

Method 1: Check the surface of the laptop and battery, now in many places, such as laptop keyboard, have carried out near the grinding treatment, the surface of these areas because of frequent human contact, a long time will make it smooth and shiny, this place is generally very difficult to renovate, and can be used as an important basis for us to judge.

Method 2: Check the laptop and battery screws, general merchants buy old laptop will have some problems, but businesses have to carry out maintenance and renovation of laptop and battery computer must be on the laptop to be demolished, so that is bound to leave some screws on the more obvious scratch, so if this screws found traces of the Armada E500 laptop and battery computers will have problems.

Method 3: Check the LCT display surface, observe the above if there was a small scuff mark, because the surface of thin LCT, can not be polished, so the above ordinary wear and tear is very diffic
The hand-refurbished laptop and battery, due to the use of civilian cleaning agents, laptop there is usually a faint scent of the above, and the laptop and battery's surface feels there will be some creamy;

Method 5: Check the laptop's serial number, by checking the laptop's serial number, we can understand the specific circumstances of the laptop and battery. General laptop's serial number are located on the bottom of the label (Figure 3), we need to carefully check whether it had been altered and was re-posted off the scene. Boot into the laptop computer's motherboard BIOS settings, check the serial number and BIOS serial number of the fuselage is consistent with the serial number on the box checked, if these numbers are not the same, the proof of the laptop and battery There may be refurbished machines. In addition, we can also use the serial number of the laptop and battery's Web site query to a specific date of manufacture of the Presario 1700 laptop and battery.

Method 6: Check the battery, most new laptop and battery computer battery charging times should not exceed 3 times, the battery should not be high in power will be 3%. If the battery charge and discharge capacity is too high or too many times, we illustrate the laptop computer has been used for a long time, can be suspected to be refurbished laptop computer. Note that, businesses may use the laptop and battery machines had been tried by others as an excuse, but the test machine under normal circumstances, when businesses are not using the battery to drive the laptop computers, but direct use of an external power supply, so the excuse obviously can not withstand scrutiny.

Method 7: Check random attachments, check the laptop all the random attachment is necessary, these accessories include driver CD, manual, warranty card, etc., because the merchants selling refurbished laptops, it is difficult to collect these accessories complete especially the product specifications, are generally self-published and can be easily identified. If the attachment is not complete, may be refurbished laptop also has. (Currently some of the models of IBM laptop and battery does not seem to really attached CD-ROM drive, and only a recovery CD, this is a rather special thing, but the warranty card and instructions are complete, please be Presario 900 treated differently.

Combination of the above variety of methods, I believe we all can tell refurbished laptop and battery computers, to prevent themselves deceived.
