Turned out the Service Tag is correct but it is not linked to the order number. Anyway, I've already been contacted via private message regarding this and my problem is being sorted out.
Hello, My one-month old Inspiron 14 5000 2-in-1 (5406) laptop doesn't turn on anymore. I tried everything suggested by the Interactive Support Agent, but no luck. I wanted to contact the Product Support but I cannot access it because the form doesn't accept my Service-Tag number.The Service-Tag I'm using is 100% correct. At least that's what the sticker at the bottom of the laptop, and the label on the package, say. I cannot confirm from within the OS because... it doesn't turn on. How do I proceed?
