1) you can't upgrade the graphics card on a laptop. You're stuck with whatever the laptop was built with.



2) You should look up the specifications for your model. They'll say what graphics card you have. Then, look up the card you have, and look up the minimum card you need. If the card you have has higher benchmark scores than the one the game requires, you can play it.How can I tell if I need a better graphics card to play a computer game?
you can't upgrade your graphics card it is built into the motherboard
