power supply contact problem?

Hi,

i have a contact problem where the power supply socket contacts the motherboard. The symptom is intermittant contact loss, when you move (or even just touch) the power supply cable near the socket at the rear of the computer. Can anyone point me to a detailed design of the socket and its contact to the motherboard, so that i can try to figure out where to solder or glue it? It is a HP pavilion xz185, but anything would be fine.
Thanks a lot,

tom
