how old is the laptop? I do know that laptop motherboards are expensive though some do find them on e bay. I'm sure you can get the manual for your laptop on the HP site if you do go ahead. I don't think it is something I would tackle for various reasons, one of which is that it can be difficult to get some screws out of laptops. I speak from experience there. I was told at the time that some manufacturers glue some screws in to place depending on where they are; I have also heard others say that when trying to take a laptop apart they have come across screws that were "stripped" - not honestly sure what that means!! Yes some laptops do come with 'proper' graphics cards.
