Use the Service Tag to ascertain warranty, hardware, software
* Go here * Enter the PC Service Tag in the blank * Click Search * For this example, I will use the Service Tag from my out of warranty Alienware Area-51 R2 desktop * The main overview page shows my expired warranty
* Clicking "View Warranty Details" shows when the Area-51 R2 shipped (start date) and the warranties
* Back on the main overview page, clicking "View system configuration" shows all hardware and software
* Clicking the down arrow right of any listing shows the specifics. So for my memory, it shows the Dell five digit part number, number of DIMMs installed
