After midnight insomnia
Finally, I got it to obey when I say sleep !

The battery remained at 100% charge after 8 hours of sleep.

This is what sleep should look like between 1AM and 10AM. That's it, no other activity as it should be.

So what did I do?
First it killed the pesky GooleSotwareUpdate (as described here)
Pesky Google acting up
.. that was active all night long and completely ignoring my sleep request.
Then I shut down all apps (especially the Google Chrome that was misbehaving).
Then I Left the Lid open and used the Sleep now command (in Apple top left)
The reason for Lid open was to see if monitor comes on after a while, and it did ! 
I had to use the Sleep command 3 times, since it came back on about 3 seconds after ?
