Can I update the graphics card?

I just purchased Lenovo Ideapad G500S-20245 from an online source. I was wondering if the graphics card could be upgraded? It has an Intel HD Graphics 4000 (onboard?). Anyone know a bit more than me about this? I've never opened up a laptop before so I have no idea. I'm teaching myself web design so need something that will run adobe products well, and maybe Wildstar when it comes out.

No, it has a graphic card chip set made into the mother board and or processor.
The graphic card chip set in laptops are not upgradeable or replaceable.
Laptops are not designed to be upgraded as to processor or graphic card chip set.

No upgrades to CPU or GPU on that laptop.
