I realy dubit that someon take a rist to update a laptop without a good knowelage in particolar by it self. Evry time you try to change something in a laptop in particolar video card when you need to unscrew everything and you need to pay attenction to the micro connectors to dont damage them.
So I dubit that an advanced user that want to upgrade a laptop need to understand what video card to buy. And not advanced user dont know to update a laptop xD
