you cant upgrade memory . most laptops have memory on the die of the chip or in the same package, such as ati mobility, radeon mobility, neo magic etc. savage ix / mx can probably upgrade memory but there is no point. maybe the geforce2gos also, but still no real reason. there are some site on pricewatch that sell mobile chips. or you can try ebay. or you can buy from me, since i've got a p3800 mpga2 sitting in a drawer that i need to sell. $130 shipped takes it
