i'm glad to say i just successfully fixed the sound card in my wallstreet to hold its connection on its own without the need for a 9v battery shoved under the connector to keep power going. my only suggestions are to use powerbookfixit due to good instructions, make sure you remove every screw there is, and don't mess with the ebm levers when the case is open. i only say that due to almost damaging my motherboard with a lingering screw on the processor cage, and the lever for my left bay now works improperly.
now, with those suggestions, i have a question to ask anyone who did the same repair. my sound card is now solid, but i can still move the power connector some. i'm assuming i probably just have to squeeze the ring down to a smaller diameter?
