Outer packaging:

First, check whether the outer packaging is complete and correct. Generally, after a laptop is unpacked, there are also power adapters, related accessories, product manuals, joint warranty certificates (the number is the same as the notebook number), warranty record cards, etc. In addition, pay attention to whether the operating system recovery disk and installation disk are the same as those of the laptop. The operating system on the machine matches. Look, these levels make it difficult to counterfeit, so be sure to keep your eyes open when buying, and remember to look more carefully!

Check the serial number on the label:

Carefully check whether the serial number on the outer packaging box of the laptop matches the serial number on the machine body. The serial number on the fuselage is usually on the base of the laptop fuselage. While checking the serial number, you should also check whether it has been altered or re-posted. In addition, when turning on the computer, you must first enter the motherboard BIOS of the laptop and check whether the serial number in the BIOS is consistent with the serial number of the fuselage. If all three numbers are consistent, there is basically no problem with the source of the laptop. If there is any discrepancy, it is undoubtedly parallel imports or assembled goods. For notebook computers that enter the domestic market through formal channels, their official agents will usually have a special label on the bottom indicating the product model.

Check the appearance and screen:

Check the appearance of the laptop to see if there are bumps, scratches, cracks, etc., and whether the liquid crystal display (LCD) has scratches, dead pixels, or ripples. , whether the screws have paint peeling off, etc. When purchasing, you should try to find a machine without dead pixels, because dead pixels on the LCD may gradually spread. Appearance is also very important. If you buy something new and it has scratches, it will definitely look unpleasant.

Check the battery:

It should be noted here that the new laptop battery should be charged no more than 3 times, and the battery capacity should not be higher than 3%. Moreover, dealers generally do not insert the battery during testing, but connect it directly to the power socket. The battery is too high or the machine has been charged and discharged too many times, which proves that it is at least a machine that has been used by others. Entering the computer's battery management software can also tell you how many times the battery has been charged. In addition, there are some special detection software, which we will talk about later. This must be checked on the spot to prevent future troubles.

Check accessories and gifts:

When purchasing, be sure to carefully check whether the product accessories included in the box, including the operating system and drivers included, are consistent with the accessories package instructions in the manual. same. Also check whether there are any gifts that should be available, such as some brands giving away backpacks, USB flash drives, mice, memory, etc.

If there are no problems with the product, try again to see if there are any abnormalities in the operation of the operating system; whether the sound effects and images of multimedia playback are normal; whether the Internet is normal; whether the cooling fan is working normally; whether the laptop mouse positioning is normal; whether charging is normal Normal; whether the fan noise is acceptable, etc.

Check the ticket and write down the after-sales service commitment in writing:

No matter what brand it is, you must consider the maintenance commitment of the notebook. Pay attention to ask these things clearly, how long is the after-sales service period, what is the specific content of the after-sales service, and how long is the maintenance and replacement cycle generally.

Generally speaking, notebook products mainly provide one-year free replacement parts and three-year limited after-sales service. The maintenance and replacement cycle of most products is about 15 days. When purchasing a notebook, it is recommended to choose some imported brands and domestic products with better after-sales service.

Require the formal warranty certificate included in the packaging. Check whether the conditions of the quality guarantee are reasonable, confirm whether the merchant can return, exchange, repair, etc. when there is a problem with the product, and also confirm the warranty period, repair location, time required for repair, etc.
