My power jack on my Acer Aspire 571 has 4 wire connections on the power jack: 2x red, 2x black.

The black cables got separated and need to be soldered. I cannot see where the cables had been before and couldn't find schematics. DC plugs only have two connections + and - right?

I don't see why it has a 4 pin connector to the motherboard. Can I solder both wires to the same ground?
