Well not exactly, some of the newer lines of Alienware laptops have upgradable video card modules so you can in fact upgrade them. I read somewhere that Dell and others already have or are working on the same 'module' feature for thier laptops.
However, for the vast majority of laptops you are correct, the consumer can not upgrade the video card.

As to your laptop. Laptop video cards are chips that are part of the motherboard of the laptop. The design doesn't allow changing the video or using any video card.
To change a laptop video care, you change the laptop.
You note about an issue that could be that you need newer video drivers. Have you tried what latest they offer?
In closing, laptops have been poor game machines.
