Easiest is to contact [NAME]-Cares to check your warranty status.
I bought a used Alienware Aurora R12 without the GPU. On the first day I turn it on, I can check the warranty status (until Aug 2022), support site can auto detect the PC and update latest driver. I can see the original full specification under the service tag. Things got strange after the 2nd day, my service tag suddenly become "no match", but on the right side of the support page still showing Aurora R12 with correct service tag, refer to the picture. I log in to my Dell account attempt to add in the R12, it can auto detect the R12, when I add the product, it show a message that "1 product added successfully", but nothing appear on the list. Anyone know what happened?   [IMAGE]
