What can i do to upgrade my video card if its integrated, this is what i have : Mobile Intel(R) 4 Series Express Chipset Family , and my laptop is a Compaq Presario CQ70-120US Notebook PC
Find out how much ram your laptop can support and buy more of it. Thats about it really. But i don't know much about laptop computers so maybe someone else can help you more.
I heard from Geek Squad anyway that its almost impossible to upgrade a video card in a laptop i think very few you can. Although your i dont think you can but could be wrong
