title_body: How to put downloaded Kindle e-books on to a Kindle device that cannot access the internet I have a Kindle device, but it cannot connect to the internet because the only internet I can access requires signing in, and the Kindle just can't be controlled accurately enough for me to select the User Name and Password fields to type in. 
  
  The Kindle itself is also registered with some Amazon account whose details I don't have. I have my own Amazon account, and I have purchased an e-book on it. I have also downloaded it from the Cloud on to the Kindle app for PC, and downloaded it (apparently on to my hard drive) from the Kindle app. So the book should be sitting somewhere on my PC. 
  
  Is it possible for me to transfer the book file from my PC to my Kindle over USB? How do I even locate the book document on my PC? 
  
  Or, to circumvent this problem, if anyone knows how to navigate sign-in screens on a non-touch-screen Kindle, that would make everything a lot easier. 
  
  (Note: I can read the book on my PC with no problems, but I'd much rather read it on the Kindle.)
