Ah! Yes. I've seen that too. And I suspect powertop to be giving the wrong=

information there.
Because, even if you ask powertop to disable hal polling (or beagle indexin=
g,=20
for that matter), it still reports as if they are running.

I'd suggest you to insert a cd into the cd drive, while running on battery,=

and see if hal auto-polls it.

That should test it. Right ?
