How To Fix Broken Laptop Charger Tip

In this modern world, there’s unlikely to find a person who does not use portable devices such as laptops, tablets, etc. If you are using a laptop for your work or school, your charger might certainly get started to wear out by time. But, it is not always damaged straight away.

If your laptop charger seems to be broken, it does not always mean that the charger is broken. After you plug in the cord, you might observe that your laptop does not show that any charger is connected, or rapid blinks, which is very disturbing.

We are here to help you fix the broken laptop charger so that you don’t need to spend a lot of bucks buying another one since all you need is a bit of servicing of your older one.

How To Fix Broken Laptop Charger Tip

The reason your charger might not be working might be because the connections inside have become loose or disconnected. There are a few tools you will need to fix your charger. These are-

• Heat shrink tubings for insulation of the wires

• Soldering tools

• Anti cutter

• Hairdryer (if you’re using heat shrink tubings)

Slice off the old sheath

First of all, make sure that your charger is unplugged before you do anything. Remove the old rubber sheath. There is a metal plug below it and it should have 2 wires joined to it.

Once you remove the rubber plug, cut the plug off the cord as well as the damaged part of the cord. Then, you have to cut the sheath from around the magnet and the magnet should slide down the cord. There should be only a plain cord coming out of the transformer box.

Next, hold the worn-out ends of the solder with pliers and heat the solder joining them to the plug to pull them off. It would be easier if someone can assist you when you do the soldering.

Slide things on for later use

You will be needing the large pieces of heat shrink tubing on the cord as well as the magnet on the wire. Therefore, slide the magnet first, and then the heat shrink tubing.

Find out which wire goes where

There will be two separate wires inside- one negative and one positive. On the connector, the negative terminal is the outer part of the connector and the positive part is the center. In the cable, the negative part is the sheath of strands and the middle wire is the positive part.

Soldering the connections

The outer part will still be connected, but the tubing that has been installed before has to be cut. Now, you have to slide the new tubing on the wire and solder them in. Thus, the middle wire will go to the middle connector and the outer wire will go to the outside of the plug.

Test plugin laptop

Now, plug everything in and check if the charging light turns on or not. It should be working now if it is not damaged. If it works, let it remain as it is and slide the first piece of large tubing down the cord, and line it up with your laptop.

The metal on the plug sticks way out, so it is better to do this while the charger is plugged in. Use a heat gun or a lighter to heat the tube and shrink it.

Building the Connector

Slide up the other tubes, one at a time, and shrink them in place. The tube will get hard and tight as it shrinks, so it will hold the wires in place and ensure that your new connector can resist bending or breaking.

Installing the magnet

The magnet will then be slid to the location it was before and zip tied tightly in place with the two zip ties. Now, cut the tails off the zip ties.

How to Fix A Laptop Charger Port

If there is no problem with the connections in the charger but the charging port of your laptop, that can be solved as well. If the port is damaged severely, you will need a screwdriver and prongs.

Make sure the charger is not connected to the socket and also unplug the laptop. Remove the battery if required, and reset the connectors in the port back to their previous positions. If the issue of the charger is more complicated, we would advise you to contact a reliable repair shop to fix your laptop port.

How to Fix Laptop Charger With Exposed Wires

Electrical Tape

When the wires exposed are minimal, this is a great solution. It can cover the exposed area and make it secure. All you have to do is cover the damaged area tightly with the tape. You can tape around the exposed area several times to ensure that it does not come off easily.

Using Sugru

Sugru is a mouldable glue, which, dries, becomes hard, and is also durable. It also ensures flexibility in the natural movement of the wires.

First of all, you have to clean the exposed area with a microfiber cloth. Take an estimated amount of the glue in your hand and warm it up by rubbing it with your hand for half a minute.

Once it is soft and pliant, roll it into a rectangle. Wrap it around the exposed wires and apply it evenly with your fingers. Leave it for a day on a flat surface as it hardens, and you can use it as usual.

Heat-shrink tubes

We have talked previously about heat-shrink tubes earlier in this article. They are tubings of a type of plastic that shrink when heat is applied, which is pretty self-explanatory. It is by far the best solution as it covers the exposed area much more securely than anything else.

First, figure out the diameter of your wire as the diameter of the tubing should be double the diameter of the wire. It’s important to maintain this 1:2 ratio. The length of the wire should also be twice as long as the length of the exposed wires.

Next, cut the tubing out and place it over the damaged area. You can use a hairdryer or any indirect source of heat to heat the tubing to shrink the tubing for secured attachment.

Assessments to Make Before Fixing Your Charger

Our intuition of “there might be something wrong with the charger” might be inaccurate. So it is better to make some assessments before jumping to those kinds of conclusions.

• There are some outlets that have separate switches for turning on the power outlet. Make sure you have turned it on.

• Ensure that your wires are properly connected. If they are, you can try reconnecting them.

• You can restart your laptop and see if the device charges after that.

• Check if the charger lights are blinking continuously.

• Check if the device charges from another outlet.

• You can try charging your laptop using another charger to make sure if the problem is indeed in your charger.

• Check if the laptop battery needs to be changed.

• Make sure your charging ports are clean.


• Before starting to fix your charger or laptop, ensure they are disconnected from any power source and also turned off.

• Do not use naked flames to shrink heat-shrink tubes.

• Do not use duck tapes to cover exposed wires.

• If the damage is too much, seek a professional or buy a new charger.

Final Word

There are a lot of reasons why your laptop charger might get damaged since it is also a piece of mere electrical equipment. But you can fix the minor damages that might result without investing in some pricey tools or replacing your charger with a new one. Now that you know how to deal with it, you will no longer have panic attacks when it stops working. You can be your mechanic, and within time, develop a new skill of fixing laptop chargers!
