If you look at the warranty site for any new computer, Dell is now including a warranty date for Dell Digital Delivery.
"Dell Digital Delivery enables you to purchase select software titles at the same time you order your computer. When you receive your computer, the software is automatically downloaded and installed from the internet."
It's unfortunate that Dell includes this as a warranty date, because it throws off LS. It seems LS finds the latest date on the warranty list and uses that. It's a logical way of determining the date, but the Digital Delivery date throws it off.
