Purchased this refurbished Dell that states it has a "backlit keyboard" and it also had a manufacturer's warranty to 2019.  The backlight didn't work but I just dealt with it thinking I could make a claim on the warranty but when I did, the seller told me to make a claim with Dell.  According to Dell, my laptop's backlit keyboard was not refurbished and that I was out of luck.  So I went back to the seller and 3 emails letter he has yet to respond.  Disappointing that a seller wouldn't make good on a misleading and false ad.
