it's an interesting approach: min/max based on power draw at idle and full
use. not sure we can get that sort of set of numbers (with accuracy?) on a
laptop. even then it's once again "numbers i have to do my own calculation on"
and having 3 hours when idle and 20 minutes when in use seems to be still a
pretty big spread.

yes ..

<obviousguy>when your machine is suspended, you can't see these numbers
anyways and the user tends to count it as "kind of off anyways"</obviousguy>
i don't see how this is relevant to the conversation at hand.
