Is anyone else's battery only lasting about half as much with the same setting as Vista?

Sorry, my battery life has gone up by about 30 minutes. What setting are you using?

My battery of laptop goes %60 Better than Vista.. Already using DVD and USB devices so more .. but goes much better than Vista.. I don't know why not. :) But i like this.At the last (about two weeks) my PC gone about 1 hour 20 mins with Vista (its last session of Vista. and i got complete backup on four DVD from my laptop) and now my PC running in last 3 hours and already working. I got one more copy of my backup DVD's by copying DVD's with Nero 9 on this machine in this time.Anyone says SEVEN USES MORE BATTERY ?? :)Cheers.DincerDincer
