99% of the time the video card is sodered onto the mobo on a laptop, and there is no AGP slot. There is one exception that I know of. There was once a Dell laptop that had the video card on a riser, and you could swap out video cards on that laptop, provided that you bought the replacement card from Dell. It was in production only briefly, and I don't even think that they make it or the riser cards anymore.
