I recently purchased a second hand Dell Precision 7520 laptop through eBay. The issue I have is that the service tag is not recognized on the Dell site. I get the following message when I enter the service tag.
You're going to need to contact the seller to find out the system history - only that way can you get it registered.
If the seller can't or won't assist, return the system to them for a refund.
The seller is the only one that can tell you - someone must have changed the service tag to an invalid one. The service tag CAN be changed -- sometimes for legitimate reasons (mainboard replaced); other times not (to cover up a stolen system, or one that doesn't have a documented history).
Your seller is your only source of information -- as above, if they cannot provide the answers, get a refund.
Thank you for the reply, but the problem is the service tag number is not valid hence can not transfer the warranty nor able to check on Dell's warranty page.
Can you help me out to register the machine?
