If the serial number SN on the D side (back cover) of the ASUS notebook, the SN on the outer packaging box, the SN on the top suitcase of the outer packaging box, and the SN on the battery are consistent, it is the original Factory machine. Of course, there are also profiteers who make replacement parts or make fake ones. If the four SNs are all the same, there is nothing you can do. The key is to go to a regular ASUS authorized store to buy the machine. They all have ASUS authorization plates. The content of the authorization plates is:

20** Year

ASUS Consumer Products

Authorized Distributors

**Computer Company

ASUS Computer China Business Headquarters
