Oh, that's interesting. When did that come in? I'm _fairly_ (although
less so now) sure that it doesn't do that on a G4 PBoko, it's more akin
to the more usual 'sleep' definition.

Well, quite. My PBoko lost about 5% charge over a 24hr period when the
battery was healthy. That's not a lot.

I think it started with the Intels.

It seems to use more than that. 5% in an hour? Something like that anyway.
