It's possible that the graphic card has the optimus chip in it, if so you're a bit out of luck
There's Bumblebee to support nVidia Optimus though

You should read this article How well will Nvidia Optimus cards be supported in 12.04?
If you find that you do have Optimus enabled and want to use it, you can install Bumblebee like so:
sudo add-apt-repository ppa:bumblebee/stable
If you are on Ubuntu 11.04 or older and want newer drivers (recommended) than the ones available in the official repos, run:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
Install Bumblebee using the proprietary nvidia driver:
sudo apt-get install bumblebee bumblebee-nvidia
sudo usermod -a -G bumblebee $USER
Note: No need to change $USER, this variable is set to your username.
Reboot or re-login.
If you intend to run 32-bit programs like Wine and using Ubuntu 11.10 Oneiric or later, install 32-bit libraries with:
sudo apt-get install virtualgl-libs:i386 libgl1-mesa-glx:i386 libc6:i386
