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.
