Because it's impossible to leave such traces on a new laptop.

Another important sign is in the manual, as shown in Figure 2, in the repair notebook manual, there are similar notes, the left is a repair notebook computer instructions, on the cover of repair related instructions, while the right is a new notebook computer instructions, the cover does not have such a description, the following for the enlarged description of the section, Please note that there are several places in the circle, which clearly indicate that the notebook contains used parts, and the warranty period is 1 years. In addition, there is a similar label on the box of the notebook, so we do not forget to check these places when we choose the notebook, if we find this kind of label, it will prove that the notebook is a rework machine.

The above mentioned original refurbished notebooks because the quality is relatively good, so the harm to consumers is still relatively small, and the other class is entirely by some underground workshop refurbished notebook computers, their quality can not be guaranteed at all. Because it is the business of their own renovation, is now posing as a new laptop to sell, of course, will not leave a mark on the notebook, so the above mentioned method for such a notebook is completely no effect, but we can follow the following methods to identify:

Method One: Check the surface of the notebook, the current notebook computer in many places, such as the keyboard near the abrasive treatment, these local surface because of frequent contact with the human body, the time will make it become smooth and shiny, this place is generally difficult to renovate, can be used as an important basis for our judgments.

Method Five: Check the serial number of the notebook, by checking the serial number of the notebook, we can understand the specific situation of the notebook. The serial number of the general notebook is located on the label at the bottom (Figure 3), we have to carefully check whether it has been altered, has been affixed to the traces. When the boot into the notebook computer motherboard BIOS setup, check the BIOS in the serial number and the fuselage serial number is consistent and check with the serial number on the box, if these numbers are not the same, then prove that the notebook may be refurbished machine. In addition, we can also use the serial number in the notebook's website to inquire about the specific factory time of the notebook.

Method Six: Check the battery, the general new laptop battery charge should not be more than 3 times, the battery should not be higher than the electricity in 3%. If the battery is too high or charging too much, it means the laptop has been used for a long time and can be suspected to be a refurbished laptop. It should be noted that the business may be the notebook has been tried by others as an excuse, but the general test machine when the business does not use the battery to drive the laptop, but the direct use of external power supply, so this excuse obviously can not withstand scrutiny.

Method VII: Check the random attachment, it is necessary to check all the random accessories of notebook, these accessories mainly include drive CD-ROM, instruction manual, warranty card and so on, because when selling the refurbished notebook computer, it is difficult to collect these accessories, especially the product manual, which is printed by oneself, it is easy to identify. If these attachments are not complete, the notebooks may be refurbished. (Some of the current models of IBM notebooks do not seem to be included in the drive disc, only a recovery CD, which is a special thing, but the warranty card and instructions are complete, please distinguish between the treatment.) In combination with the above methods, I believe that we can be divided into a clear renovation of the notebook computer, to avoid being deceived.
