Edit: Actually, I take back what I said. After checking your specs, you should be able to run Crysis 2. Probably not on max settings, but your GPU, CPU, and Ram are all at around recommended settings. You should be able to run it at a decent framerate at medium or low settings.
I recommend upgrading your CPU. You've got a G1 socket so you can put an I5 or an I7 in there and improve performance. You should be fine for Crysis 2 even with what you have.
If you want to be sure go here and it will tell you if your system can run any particular game or not:

From what I see you should have no trouble running Crysis 2 based on your specs. Probably not on Ultra settings, but you should be able to run it on maybe a little better than low.
For the other posters in this thread, this an article that shows benchmark scores for his GPU. He has a gaming laptop. It's not an Uber rig, but it's good enough for most games. It could be made a bit better with an upgrade to at least an I5, but OP should be fine with what they've currently got for playing Crysis 2.

The integrated GPU isn't horrible as it's an Intel HD 3000 or an Intel HD 2500 [I think, it's hard to find any info about the exact GPU your laptop uses, but it's running DX 11 so it's probably at least a 2500 and given the model of your laptop a 3000 at best]. I'm pretty sure it will run Crysis 2. I'm not sure about that, but it seems safe to assume it given the information you've provided. 4gb of Ram isn't bad, your CPU could do with an upgrade but it's decent for a dual core.
Unfortunately as it's an integrated GPU and a Laptop at that, the only way to upgrade the GPU would be to replace the entire Mobo, and you'd need a new PSU as well. You're honestly better off buying a new laptop to upgrade GPU capability.
It will run a lot of games. Even some new stuff will run on it such as Dead Space 3, Grid 2, Fifa 2012, Guild Wars 2, and Splinter Cell Blacklist [All on -low- settings] at a decent frame rate [30fps+] with that GPU and a decent CPU such as an I5 or an I7, and it may run them even with the I3 he has. 4gb of Ram is fine for most games, though upgrading to 8gb isn't a bad idea, OP should be fine with 4gb as not many games use more than that anyway and those that would won't run on what he's got anyway.
It'll run Orange Box at medium to high settings. That will net OP Half-life 2, both expansions, TF 2, and Portal. All of which are excellent FPS games. OP can Run Doom 3 BFG edition as well which will also provide quite a bit of gameplay as it includes the expansion for Doom 3 and the first two Doom games as well.
OP is sitting on a pretty good laptop for casual gaming. Not exactly top of the line, but it's decent and should run most games that aren't brand new and huge graphics hogs. Crysis 3, Gta IV, and Farcry 3 are out of the question for example. None of those games would be playable, but he's not too bad off for most other games.
