I'm not an IT guru, or even an _experienced_ user - been using Fedora / 
Cent for about 4 years. And, it's the only linux I've really used.

Anyway, in my limited experience, various boxes get different options. 
I've installed Fedora or Cent on about 7 machines (including 1 laptop); 
somehow, none had identical options in that department. I *think* it may 
be be MB, or the bios ... ?? On one machine, the user login screen 'Shut 
down' feature *tries* to shut down, but just returns to the login screen.

I know that the bios have settings for what to do when the power switch 
is used, and that there is a Preferences feature for this also.
