Re: Upgradation of HP Laptops.
There are VERY few laptops that give you the ability to change GPU's. Most laptops have the GPU soldered to the motherboard. I'll look around and see if your model has that ability.
EDIT: From my reading, It would appear that the GPU is not interchangeable on your model. Sorry.
