The current laptop is a high-end consumer product for most of the friends, so every friend who chooses a laptop wants to buy a product that makes him feel good. But now in the notebook market, there are quite a few refurbished laptops. Especially for friends who like online shopping, online merchants carry out corresponding repairs and refurbishment, and then put them on the market for sales. Since these laptops are similar in appearance to brand new laptops, it is easy to be regarded as a brand new notebook by some unscrupulous profiteers. Selling, let the sales expenses suffer. Here are some tips for identifying and refurbished notebooks: Method 1: Check the surface of the notebook. Now the laptop is sanded in many places, such as the keyboard. The surface of these places is often in contact with the human body. It will make it smooth and shiny. This place is generally difficult to renovate and can be used as an important basis for our judgment. Method 2: Check the fixing screws of the notebook. The old laptops acquired by the general merchants will have some problems. The merchants must disassemble the notebooks when repairing and renovating the laptops. This will inevitably leave some obvious on some screws. Scratches, so if you find such traces on the screws, the laptop must have problems. Method 3: Check the surface of the LED display to see if there are any traces of wear on the surface. Because the surface of the LED is very thin and cannot be polished, the above wear is generally difficult to remove. Method 4: Check the smell on the surface of the notebook. The notebook that has just been opened will have the taste of an industrial cleaning solution. This taste is not very good. The hand-refurbished notebook, due to the use of civilian cleaners, there will be a faint scent on the notebook, and the surface of the notebook will feel a little slippery; Method 5: 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 a typical notebook is located on the label at the bottom. We have to check carefully whether it has been altered or re-applied. When booting, enter the BIOS setting of the notebook's motherboard, check whether the serial number in the BIOS and the serial number of the body are consistent and check with the serial number on the box. If these numbers are different, prove the notebook. It may be a refurbished machine. In addition, we can also use the serial number to check the specific factory time of the notebook on the notebook website. Method 6: Check the battery. Generally, the battery charging time of the new notebook computer should not exceed 3 times, and the power in the battery should not be higher than 3%. If the battery is too high or there are too many charge and discharge cycles, it means that the laptop has been used for a long time and can be suspected of being refurbished. It should be noted that the merchant may use the notebook as an excuse for being tried by others, but in general, when the machine is tested, the merchant will not use the battery to drive the laptop, but directly use the external power supply, so this excuse Obviously can't stand the scrutiny. Method 7: It is necessary to check the random accessories and check all the random accessories of the notebook. These accessories mainly include the drive CD, manual, warranty card, etc., because it is difficult for merchants to collect these accessories when selling refurbished laptops. In particular, the product manuals are generally printed by themselves and are easy to identify. If these accessories are not complete, the notebook may be refurbished. (Currently some models of IBM notebooks do not seem to have a driver CD, only a recovery disc, this is a special thing, but the warranty card and instructions are complete, please treat them differently. In short, everyone still has to be in the formal The purchase of the business is reliable, can not lose its own interests because of cheap, try not to go cheap, buy too low-priced products, otherwise it is likely to be a refurbished machine.
