No, indexing would have been done in only a few minutes with just a few books.

Cool, so at least we know that that works. I can understand why you went to the AC charging, though.

From what I know, the green light should stay on. But I've never left it plugged in for 36 hours before so maybe it does turn off eventually. But I doubt it.

And having been in sleep mode for the past three days, it now shows.... 90-95% power remaining? So there is _some_ power draw in sleep mode. Wonder if there is power draw in OFF mode?

Yes, there is some power draw in sleep mode even with wireless off and no indexing. As for OFF mode, there is probably an even smaller draw from the battery, but experience has been that the power consumed by turning the Kindle off and on takes more energy than simply letting it sleep. So I would recommend just letting it sleep.
It sounds like that maybe the cord or connector was loose, and it just didn't charge the one time, and eventually the charge ran down low enough to trip the battery warning. Another possibility could be a brief power surge or power outage while it was plugged in; I could see how this might put the Kindle in a state where it would stop charging, but that is pure speculation on my part and I don't think nearly as likely as just a loose cord or connector.
