After that cut out sheath surrounding the magnet, and the magnet should slide off the cord.

Step 5: Test Plug in Laptop

So, plug it in and see if the charging light shows up. It should start charging.

Slide up the other tubes one at at time and shrink them in place. The tube gets tight and hard when it shrinks, so it holds the wires in place, and makes your new connector resist bending and breaking.
