Hi [NAME] the Dell System Service Tag is a unique alphanumeric identification for your laptop. Dell SupportAssist has already detected your laptop's Service Tag.  When going to Support for Alienware Area-51m Drivers & Downloads, click on the [Detect Drivers] to customise updates for your laptop.  When your new owner application for Dell Product Registration is confirmed, you will be given access to your Dell Warranty options, to extend or upgrade your Dell Warranty. The vendor should notify Dell of the owner transfer. If the vendor is not the owner, Dell support will request copy of invoice so that your ownership can be validated.  Go to bottom left hand corner and type msinfo32 into search, System Information will confirm your mainboard's System Service Tag, etc.
