I recently transferred a new Gigabyte motherboard into an old Dell XPS 8100 case. The case power switch, power led and HDD indicators weren't standard layout but I expected that and was able to cable the motherboard correctly.

The question I have is that the power switch lead has THREE cables. The switch consists of a brown lead (I'm assuming that is negative, might be wrong) and a blue lead. The blue lead has an extra cable coming out of the header plug, so not the cable, but the plug.

Basically Dell has soldered two blue leads together two create two end points for the switch. One of them I have placed in the Power Switch + and the other I have running to a no-pin on the header. Does anyone know what this lead is suppose to connect to? Could it be to the reset switch? I have no idea.

Edit: Here is a link to a picture that shows the header. The little blue loop is the extra cable.

Best I can figure is that it is another ground. Would there be any advantage to connecting that lead to a ground as well?

You could very well be right though.
