Unfortunately, you cannot
upgrade/replace your video card on your laptop or any laptop at all. since laptop is small, computer companies are trying to squeeze eextremely
thing onto the main board (called mother board), means, eextremely
thing is built-in onto the board. the only things you can upgrade/replace is the harddrive, memory. also, some laptops will allow you to replace your keyboard and the screen, like dell, but not all companies would let you do this.
