Alienware M15x laptop I'm using Windows 7. Well, I was in the need for the review of my Alienware, so I was observe at the bill and said there is nothing there. This is the first thing I want to know. The other thing is that I was thinking of upgrading my RAM on my M15x. So urge the supported model for it. I'm using 2x2GB of RAM in it. Please give me some suggestion regarding this. I really need information about it.
