Step 4Back to the daughterboard.
The last part is to get the extension hooked up to the daughterboard and a connector on the extension
De-solder the connector on the daughterboard, taking note of the polarity. The desoldering braid is useful here. The shielding on the connector is aluminum and will wick the heat, watch the temperature on the board, it will heat up.
The vias on the board are small, too small to solder directly to with the size of wire I'm using. I snipped the pins off the connector, and resoldered them into the vias, so that there is a larger pad to solder to. The speaker wire is straightforward, again, strip and solder the wire. Trim it to the length you want, for the location where the final connector will be. I picked the back of the screen, where it is out of the way.
Prep the lego connector the same as before, but this time match the connector with the power one, so that the orientation will be the one you want in the final installation. Mark the polarities, solder everything up. Remember to pass the cable through the hole prior to soldering. Hopefully at this point everything should be in working order, so reassemble the laptop and see if it boots. Be careful with the ribbon cables, as they are fragile.
If everything works, use some CA glue to route the external cable and to affix the laptop end of the connector where you want it.
