Your post is confusing, so I'm not sure what you're asking. I'm going to guess that you need a way to connect the old cable that had USB-A plug into your new laptop's USB-C port. You need a USB-C to USB-A adapter, like this one. Many brands and styles are available and are generally inexpensive. [IMAGE] Alternatively, you can buy a new cable that at one end has whatever plug the Nikon requires and at the other end is USB-C. If that wasn't what you were asking, then please clarify.  
I have and older XPS 13 that I was able to connect to my Nikon D7100 with a cord.  Now I have an XPS 13 9305.  Can you please tell me how to connect it to my computer with either a new cord or else purchase an adaptor for the USB older cable.  Thank you.
