But if there is, it would be offered by your computer's maker. There is no generic such dock today.
The Expansion Port on laptops connect to docking stations, right?
What I would like to ask is whether there was any way to connect another motherboard to the laptop via the Expansion Port, in order to add extra RAM, PCI cards, proccessors, etc.
Kind of like the ancient Powerboook Duo Duo Dock.
