It IS possible to do this, without damaging either the motherboard or even the old socket, with flux, solder wick, and patience." I'm a little confused as to why the original socket would have to be de-soldered. Can't this adapter just be plugged into an empty CPU socket? Or is it the case that the M100 case can't close again because of something so high in that socket pressing against the keyboard circuit-board? Thanks for the info! -- Gary Weber g...@web8201.com
