Can my graphics card be upgraded?

[Frey]

I'm considering upgrading my laptop a little bit to be able to handle the new EP's coming on. The thing is I have no idea about techy stuff, so I wanted to ask:

How do I know if my graphics card can be upgraded, and if it can, how do I know which new graphics card I can get? I read the user's manual but didn't find anything useful about it. I've heard that with most laptops you can't just replace it, but I haven't found anything about how to know whether it's possible or not.

The laptop is a Samsung R580 with an Nvidia Geforce 310M, running Windows 7.

Thanks in advance

EDITED to add: Speccy says I have a couple PCI Express slots available, for whatever that means. I've read it has something to do with graphics cards so I thought it was important.

Hi, Frey.

I've done some checking around and unfortunately it doesn't look like you can replace the graphics card in your laptop. Most laptops are manufactured with the graphics processor directly soldiered onto the motherboard, built into the processor, or (in your case) both. Some high-end gaming laptops can have the graphics card replaced, but the majority of laptops on the market cannot.
