How easy/hard would it be to upgrade the video card on a HP laptop?

I found a good deal on a DV6 model and would like to upgrade it's video card. Is this advisable?|||Impossible, actually. The "video card" is not a discrete separate card like you find in desktops. Like 99.9% of all laptops, it is a chip that is soldered to the same board as the processor, bus controllers, memory slots, etc. This board is also known as the motherboard in a laptop. These chips are not removable from the motherboard due to trying to cut down on weight, space, and also for heat issues. Only in very high-end laptops ($4000+ usually) do you find "removable" video cards. However, these are quite rare and very difficult to find, service, and get parts for, not to mention, very cost prohibitive to maintain after about a year.|||simply --u can't ---u have a laptop not a destop pc
