Hello guys, I own a Lenovo Ideapad Y410p which have a Nvidia GT755m 2gb GDDR5. But when I play NFS Most Wanted 2012 by using the laptop battery, it does not uses the nvidia card instead uses the Intel HD4600 graphics so the game is lagging. When I connect the laptop to the charger, it automatically uses the nvidia card. My question is,how to enable the nvidia card to play the game while just using the battery?? Thank you guys. Gamers rocks!!
