This refurbished unit is working great, it was certified and came with an upgrade to Windows 10, all the necessary paperwork and the AC cord. No blue tooth so you will need a USB WiFi adapter and I did purchase the extended warranty with it as a backup.All in all, it's operating fine, just a couple of scratches on the casing I can live with that.Oh, I do have one CONS:The keyboard a mouse is not the best quality, I do wish there was an option to upgrade these accessories, now I need to buy one.
