Now you've got your washer with its copper electrode dangling. If we were to just stick this into the laptop socket, the electrode would just kick around inside and not ever make contact. So we need something to push it against the outside. This is where the mounting tape comes in. Stick one side to the electrode, and the other side will press against the center rod in the power socket. It's double-sided tape, but only uncover one side.

This is a good time to give it a try. Gently work the electrode into the socket until the washer is flush with the surface of the laptop. If you have a multimeter, see if the washer is connected to the laptop's ground. The outer metal bits of most of the connectors on your laptop will be equivalent to ground, so check for continuity with those.

Once you're satisfied that the electrode is making contact, epoxy the washer to the face of the laptop. Make sure it's centered and even. It's not completely impossible to remove it once you've done this, but it won't be very easy .
