The laptop in question is a HP Pavilion Dv4t-1600. Here the "Notebook Tour" user guide states it has an ExpressCard 54 slot, but does not mention if it supports ExpressCard 34. Also, this "External Media Cards" user guide, fails to indicate if the ExpressCard 54 can fit 34, either. I'd really appreciate a definite answer whether an ExpressCard 34 works, and especially if it will cause an empty space or gap, since i do not want debris,etc going into the laptop.
