How To Fix A Laptop Charger Port

A faulty charging port is one of the typical issues that we often face. However, instead of just moving onto a new charger or laptop, why not first try to make efforts to fix the problem by identifying the source.

For example, the source of the problem may lie with the power jack or cables. It can even be the battery itself. But, once the problem has been discovered, fixing it won’t be difficult!

Identifying the Source:

Main sources which cause problems and make your charger port unworkable are

  • Broken cables
  • Faulty adapter
  • Bad battery

If the cause is not one of the above factors, then you should seek professional help

With the assistance of a multimeter check whether the charger is providing your laptop with proper voltage or not. If the voltage provided is fine, then it indicates that the battery has some issues. Whereas, if the voltage is lower than required, then it is an indicator of some broken cables.

Fixing The Problem:

If the problem is deeply rooted, then prepare your technical gear to fix it.

Fixing The Adapter:

If the charger is faulty, then the most effective solution is to purchase a replacement. But, if you know the physics behind electrical circuits, then you can fix it by yourself.

Firstly, turn off the power. The adapters usually come sealed tightly within a plastic covering or case. To fix the problem, use a knife and cut through the plastic covering. Remove the top. Now, you have access to its internal components. You will find the interior is packed with a motherboard, transistors, and capacitors. Focus, if any capacitor is swollen or not. Swollen capacitor indicates that it has worn out and requires replacement. Purchase a new capacitor and fit it into the adapter.

Fixing The Cable Breakage:

Broken cables can be detected if you know whether power is surging through the adapter or not. If your adapter comes with an LED light then you would instantly know this when the adapter is plugged in.

If the LED lightens up when connected to the power source, then it signifies a problem with the DC output cable. However, on the contrary, the problem may be due to the AC cord if the LED is not lighting up.

For fixing the problem, cut through the problematic cords’ plastic covering and shave its choke. Take care while connecting the connectors to the correct wires.


Fixing the problem does require an effort but it would help you get rid of the issue. If you think the problem is out of your league, then don’t push your limits. Contact a professional!
