I Googled the 'sleep verb not supported' and found that at least one
person experienced the same problem when Chrome was open with a bunch
of open tabs, which is _always_ the case on my laptop. I closed
Chrome, and the hibernate button worked. I'll see when next I open
that laptop whether hibernate really worked this time. (Could it be
Chrome that was draining power even when the machine was hibernated?)

No lights were on or blinking. It _looks_ to be shut down.

The options in logind.conf (which I take it you meant) were all
commented out, and none defaults to hybrid sleep.
Thanks for your insights.
