Are you able to suspend and resume the EliteBook? In my case the power
usage drops after a suspend-resume cycle and it would be interesting
to see if your laptop behaves the same way.

There should be some rc6 stats we can obtain from the driver (in order
to see how much time the hw is spending in each state) but I'm not
sure how off hand. I'll follow up if I find out how to get them.
