I just bought a HP Pavilion dv4-1427nr Entertainment Notebook PC amd turion x2 dual core mobile rm 75 2.20 ghz 8 gigs of ram. It has a video card ati radeon hd 3200 graphics but I google it and found out its not a video card it is on board video. Not as good as a video card. Can I upgrade this system buy a video card and install? Or how doI find out without opening the laptop up to actually see the motherboard and see if it has a slot?
