I don't think the problem with CCC is about the driver.Unfortunetly for laptops the VGA drivers can be downloaded only from your laptop manufacture site.This is my experience with my ex-Hp 9640us model with nvidia 8600M GS.The only i could install the normal nvidia drivers from their site is through a moded inf file.
