Ralph has a Dell computer that spins up the hard drive when it's asleep. What gives? Leo says it's probably running a program like mail in the background and it will still retrieve the email from time to time. Windows 10 also phones home from time to time to check for updates, indexing files, etc. He can always run the Microsoft Process Explorer, as part of Sysinternals, to see what's doing on.
Ralph also has a printing problem. It will print a test page, but nothing else. Leo says that the printer driver is broken, and it's causing problems with the print spooler. So just go to the printer website and download the latest drivers.
