Have a W3615 with D945GClG1 MB. Trying to determine if MB or switch is faulty. Have replaced faulty PS. Anyone knowledgeable or have one of these systems or MB in another unit, please advise of pin order and exactly how the connections are made to the pins from the power switch, power led and hdd led. Have seen diagrams of MB without actual connections but since mine is still not working, just want to verify before replacing. Thanks.
