I've seen them on the Gateway website as components for other laptops with a part number that why I'm asking. It also says bluetooth is optional for my laptop that's why I assumed it must be a module. I also see a empty mini-PCI slot next to my wireless card also.
it might take some time to get an answer back regarding slots inside a comp, since it would require anyone to take the machine apart. If u dont see it at the bottom as previous models, then good chance that it will be situated underneath the keyboard
