Aha. That is indeed the secret. Unplug the power, get power consumption stats, plug it back in and they disappear. I suppose this is a feature of ACPI and/or what the hardware can measure. I'd have been much less confused if there was some kind of clue that this info would be displayed when off mains, such as a placeholder.

Oh, that.
Silly me. Hadn't even thought about that. Thanks.

ACPI doesn't report power consumption, it reports change in battery state. So if you're on AC, the interface that would tell you power consumption is instead telling you how fast your battery is charging…
