How to tell if i can upgrade my video card

[smuffin]

Hello,
I own a Lenovo Ideapad Z565. This laptop comes with an ati mobility radeon hd 4200. Now it really sucks when dealing with game playing and I was looking to upgrade. However, since it is integrated im not sure if i can add a card onto it or not. Please help :]
