[nitpick]The “computer” is off, only the RAM memory remains on. CPU, video, HD, etc, are powered down.[/nitpick] (everything else in your post was quite accurate, though)

Nitpick noted. 
I was trying to give a somewhat non-technical answer to the question, so I might have lost a little accuracy. I meant that the computer was on in the sense that all power has not been withdrawn, like it is in hibernate. I could have stated it better, though.

Meanwhile, back at “Display”
“Screen Saver” tab
“Power”
There is a “hibernate” tab.
When I “enable hibernation”, (apply) 
Hibernate is added as an option to “When I press the power button”, “When I press the sleep button”, and “when I close the lid” under the “Advanced” tab.

Oh, I knew all that. Thanks anyway, though. I meant that there’s no direct key combination to hibernate the system, whereas Fn+Esc will put it into sleep instantly. No equivalent hibernate option.

I don’t have a “sleep” button, but I just set the power button to send the laptop to hibernation land.
