For this question, why don't the admins here make some annoucement or something that says "LAPTOP VIDEOCARDS CANNOT BE UPGRADED UNLESS..." And specify what models actually have this capability
Agreeing with most the other people who replied, this question is getting annoying.
And to CarpeNoctem, please don't ask a question in an unrelated message. I'm not an admin here or anything, but I find that just plain stupid. Not only that, but less people will actually see the question!
