Connections/schematics for M4600/M4800 touchpad/buttons? (Right buttons not working)

If anyone has acces to the connections/schematics for the M4600 touchpad/button assembly, I'd love to see them! For some reason both the right buttons have stopped working. Tried to disconnect/reconnect  the 14 pin "touchpad cable from the mainboard, but unfortunately this did not do the trick. Need to look a bit deeper - so would love to see the schematics or at least the pinout of the connector(s)... (It's a button - how hard can it be to fix... ;-)

Thanks and best regards,

 Anders
