More like: Resume = High Power State.  Or better still:

	Suspend = Go to low-power state
	Resume = Return to high-power state

A suspended device must, of course, be idle.  But an idle device need
not be suspended.  A device can remain in a high-power state even while
it's not doing anything.

Presumably "OFF state" means no power at all.  I don't know what 
"Retention State" means.
