@Neo7: when i turn on my gfx card i get about 1 or maybe about 1 1/2 hour backup on a full charge

yea...with the aero features on and the card being on...the laptop back-up really tanks. now that i've turned off the aero i have seen some improvement in back-up...but ofcourse if i'm playing a game under full 3D load..doesn't do much for my back-up.
