The computer itself is great. It's low power consumption, ideal for an RV or boat installation.  HOWEVER,  it arrived without a single piece of paper.  which would not be a problem IF the product key for the operating system was set up on the operating system.  I tried a couple of "tips" from the friendly local internet but no joy.  THERE IS NO SERVICE INFO, SELLER INFO, OR ANY KIND OF CONTACT INFO of the seller.  So I'm stuck and this is a big Zero unless and until I can activate the software.  I have several other refurbs and they all had the correct product key,  this one is  "exceptional".
