I think too that this is what happens, how can I prevent it?

This is a unit that seldom will have a user logged on to the hardware screen
(there will be no monitor attached on the final deployment).

The only way to use it will be via SSH or VNC and both require the system to be
running to get to it. It is much like a server system, but I installed Desktop
in case I had to do some admin work on it which requires some web browsing and
the like.

I found an AskUbuntu question that went without a solution:

What gives?
