I ordered a M4-ATX from you guys with overnight shipping and just recieved it. I also have a Carnetix p2140. My goal is to have the computer power on when i unlock the car. I cant seem to figure out what i need to do? Can i do this with either the m4-atx or the p2140 or do i need both connected to make this work? Can it be done? It is a regular Atx mobo.
