i just purchased a couple of weeks ago a HP ze4547wm laptop...and on the bottom there is cover for a mini pci slot...i know some models of this laptop have built in wireless where this model does not...what my question is is if i get a wireless mini pci card will it work in this particular model...i have heard that the antenna is already biult into the screen but i cant comfirm or deny that..and of course i called HP and they have no idea if it will work or not..any help would be greatly appreciated
