apart from the fact that they are laptop mobos; the concept is the same as a desktop pc
if every thing was to fit, you would have no probs
if you were to try to swap the mobos; the mobo would be the wrong shape, size, port locations, ram location, cpu location, screen connector wont fit, keyboard and mouse connectors wont fit, battery wont fit and wont work, the list goes on....
oh yea; the dc psu probably wont work either
the motherboard is the main part of a computer that everything connects up to, different motherboards have different port and connector locations and different compatibility levels with certain things
