Step 1: Slice Off the Old Sheath
Firstly unplug the charger from both power supply and the laptop, slice away some old rubber sheath. Inside it is a metal plug, and 2 wires are supposed to be soldered to it. One is in the center of the wire from the charger, and the second is a short one connecting to the metal strands from the outer part of the charger. Meanwhile, note where each wire is connected.

After that cut out sheath surrounding the magnet, and the magnet should slide off the cord.
Now you should have at hand only a plain cord coming out of the transformer box.
Grab the frayed ends of the solder with a pliers and heat the solder joining it to the plug to remove them. A vise or an extra pair of hands helps with all the soldering.
Step 2: Slide Things on for Future Use
However, keep safe the magnet on the wire and also the large pieces of heat shrink tubing on the cord for later use. First, Slide the magnet and then the heat shrink tubing.
Step 3: Find Out Which Wire Goes Where
Right on my connector the negative is the outer part of the connector and the center is the positive. Also, in the cable the negative is the sheath of strands, and the middle wire is the positive. They are all normal. There is a descriptive diagram of the transformer box as well, see the pictured below. STEP BY STEP HOW TO FIX LAPTOP BATTERY – weak & DEAD CELLS
You can make use of a multimeter to check you have the wires correct.
Step 4: Solder the Connections
Looking at the picture below, you will see the outer part is still connected, but I cut off the tubing i had installed before.
Slide the tubing onto the wire, and solder them in. And on my plug the center wire went to the center connector, and the outer wire went to the outside of the plug.
The picture below shows the tubes in place so the two wires can short out.
Step 5: Test Plug in Laptop
So, plug it in and see if the charging light shows up. It should start charging. If it does, leave it plugged in and slide the first piece of large tubing down the cord and line it up with the computer. The metal on the plug sticks way out, so it is recommended to do this while its plugged in. Use a heat gun or lighter to heat the tube and shrink it. I used a matches.

Step 6: Build the Connector
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.
Below is my connector with all 5 large tubes shrunk on. It feels pretty solid.
Step 7: Install the Magnet
In conclusion, I don’t really know the use of magnet, but the manufacturer found it important enough to put it on, so I also followed the rule.
After that, slid it to about the location it was before and ensure it is tied tightly in place where the two zip ties. And then cut the tails off the zip ties.
