    During beta the drivers were not out yet so you either selected the card in BIOS or both cards would be on. Now as far as I know he drivers have been out for a while now and yet I still see a significant battery life difference between selecting integrated graphics in bios and integrated graphics when bios is set to switchable. If anyone knows whats going on please post a reply.
