how do ypu work that out? when you buy a Dell you choose your config on their website, if you want more ram just specify it when youbuy the machine. If you want it later then get it from wherever you want and stick the stuff in. Ram upgrades are user upgrades, they can't have a user upgrade invalidate a warranty, it's not legal. That's why Laptops have their expansion slot under a little flap on the base.
