Can you upgrade a laptops video card?

I herd you couldn't.. so basically if you have a crappy on-board card or whatever, you can't make that any better to play higher demanding games?|||Its not always impossible, but for the most part and for the practical user it is very hard and expensive to do.|||It depends on you specific laptop. Very very few actually allow for your video card to be replaced, but the ones that do all cost upwards of $1500.|||Very few can be replaced, most are soldered on, check your documentation
