How to identify whether your laptop is a prototype refurbished machine?

1, look at the serial number. Most notebooks should have the same serial number on the body and battery. If the serial number of the battery is different from the serial number of the host, it is very likely that the laptop has been replaced. In addition, when purchasing foreign brand notebook computer products, whether the serial number of the fuselage is consistent with the battery and outer packaging is a very important basis for checking whether the products are parallel imports. You should know that foreign parallel notebooks are not guaranteed in China.

2, look at the anti-theft lock hole. If there are fingerprints, it means that the notebook anti-theft lock has been inserted, and it is probably a prototype.

3. Look at this foot. If it is worn and dirty, it means it has been used, and the workbench on the production line is not so dirty.

4. Look at the cooling fan. If there is a thin layer of dust on the fan blade, it means that it has been used for more than a week.

5. Look at the date of production. Notebooks made three months ago are still on the market, so be careful. The sales of electronic products are very fast, and it is impossible to keep a cost in the channel for so long.

6. Look at the keyboard. The keyboard of the new notebook is clean, but it won't glow. There will be dust in the gap of used notebook keyboard, and several commonly used keys will be polished.
