Dynamic IT Hardware, the seller, was unable to explain how to get the touchpad to toggle on/off. Did not seem to know why the OS didn't bring up the proper screens. And they were unaware of a third party app which is available through the Microsoft Store which may or may not solve the problem and which may or may not cause other problems.Don't know if this is a common problem with refurbished laptops with what seems to be a standard after market OEM Win 10 OS - not a Dell OS.Their solution was to return the laptop.I did get the Dell Touchpad Assistant app from the Microsoft Store and it did allow me to toggle the touchpad off and on. NOT A RECOMMENDED VENDOR if you are not pretty technically savvy. I got their support through the Amazon Message Center. (search in the search box for "Message Center". I didn't know there was a message center. LOL. It worked OK I guess. Only took a few minutes to exchange messages.)The laptop itself seems fine so far.....  So far...  Very clean and undamaged. I will update if need be.
