Step 1: The Starting Point
I looked about the house for an acceptable connector, hoping that I'd find something with the same pin spacing, but it is an uncommon layout and spacing. I decided that the best route then would be placing the connector on the exterior of the laptop, and hopefully adding in a breakaway feature to prevent damage from similar accidents. Ultimately I settled on a lego technic wire, as it pulls apart under stress, can handle the amperage involved, and is a modular low-cost solution. (Keeping in mind that they aren't liable if your project catches fire or other harm befalls it.)
