Find out what model laptop you have. The 1715XCDS has an integrated 4MB ATI mobility video chip. The only models that I can think of off the top of my head that have modular VGA boards and use the GeForce chip are the 3000 series (GeForce2Go, 16MB) the 5105 series (G4-440Go, 32/64MB), and the 6100 series (G4-420Go, 16MB). The M10/15 series have a modular card as well, but it comes with the system board and I can't remember which NVidia chip it uses or the amount of memory (and I am too tired to look it up right now).
