If your laptop charger port is faulty, this guide will quickly teach you how to fix a laptop Charger Port. Before taking any drastic actions like buying a new charger or replacing the charging system, make sure to go through this tutorial and see if you can fix the problem. This guide will help you narrow down where the problem lies, and the most economical solution.

How to Fix a Laptop Charger Port

Several factors can contribute to your laptop’s inability to charge, the most common of which is an unreliable connector or a damaged charging port. It is possible that you may have to disassemble the laptop after determining the source of the charging problem, which is usually the charger port.

A more in-depth examination will assist you in identifying the exact components that require replacement. Having said that, we strongly advise you to seek additional technical and professional support if you find yourself in over your head with this repair.

In order to repair a laptop charger port, you must first determine the source of the malfunction. The power jack, if it is linked to the motherboard, can be readily taken out and replaced with another.

If, on the other hand, the power jack becomes soldered to the motherboard, you’ll have to remove it from the motherboard and replace it with a new, working version. If you are unable to locate a functional jack, you might potentially use a pigtail to replace the power connection configuration.
The damage to the port connectors could be significant, necessitating the use of prongs and a screwdriver to restore the connectors to their original shape. Tweezers can also be used to reshape them if they become out of shape.

How to Identify the Problem

Before you do anything further, you must first determine where the charging problem is originating from and how it is resulting in the malfunctioning charging port. The most common causes of a laptop not charging are a broken battery, a ruined power adapter, or a tangled mess of wires and cords.

To begin, use a multimeter to determine whether or not the charger is producing the proper voltage. If the charger is functioning properly, the problem is most likely with the laptop’s battery. This means that you will very certainly have to replace the battery entirely.

You can rectify the problem if the power adapter isn’t producing the proper voltage, which can be accomplished by utilizing the first of the two options outlined below. If there is no power flowing out of the adapter, then it is possible that the cabling is faulty. In the second choice, we delve even deeper into the issue of faulty cabling and how to address it as fast and economically as possible.

How to Deal With a Faulty Adapter

The adapter is connected to the mains energy via a plug, and it converts alternating current to direct current. As a result, you should exercise extreme caution when working with this electrical equipment. If you are unable to take the necessary precautions, you should obtain a replacement charger, which is typically readily accessible at your local laptop repair shop, or seek the assistance of an electrician to remedy the problem.

With the proper safeguards and a basic grasp of how electrical circuits operate, you should be able to repair the adapter on your own without assistance. To begin, turn off the power and unplug the charger from the main electrical socket.

In most cases, the laptop power adapter is enclosed in a plastic case that is sealed with super adhesive. If yours is comparable in appearance, set it on a firm surface and use force to pry the two plastics apart from one another. To break the seal between the two plastic components, insert a sharp knife or screwdriver between the two pieces of plastic. After that, carefully pry the charger apart to uncover the internal components of the battery.

The motherboard, which contains transistors and capacitors, can be found on the inside of the case. Swollen or popped capacitors are a common indicator of a faulty adapter or converter. Purchase another capacitor with the same capacity as the damaged one (they are inexpensive) and replace it with the new one to address this now minor issue.

Use a voltmeter to check the continuity of the cables to ensure that they are not damaged in any way. When the adapter is linked to alternating current power, use extreme caution not to contact the PCB board. It is possible to completely replace the DC cable outlet at this point if there is a problem with it.

It is important not to swap the positive and negative DC current outlets on your laptop, since this will result in the battery not being able to charge properly.

How to Deal with Broken Cables

The connection that connects your laptop to its charger will fray eventually. Fortunately, you are not required to purchase a new one if this occurs. Some laptop adapters have illuminated LED indicators that illuminate to indicate that they are getting electricity. If your adapter is equipped with such a mechanism and the LEDs illuminate when the device is connected to the mains energy, the problem is most likely with the DC output cord.

Here are some easy fixes for cables that have become frayed:

  • To determine whether or not there is an output voltage from the adapter, you should first check the AC power cable using a voltmeter to establish that there is no output voltage. If the electricity from the AC cord is not providing the necessary level of power, you should be able to figure out where the problem is coming from rather quickly. One of the most common causes of electrical problems is simple things like damaged fuses, malfunctioning outlets, and cut cables. In the case of the latter problem, the main AC cord should be replaced (they are cheap).
  • Assuming that the AC cable is in good working order, the problem is most likely with the adapter or with the DC outlet cord. A telltale indicator of a bad outlet cable is a laptop that only charges when you move it or set it at a specific angle; this indicates that the cords are broken from the inside.
  • L connections, such as those found in the majority of HP laptops, are less prone to damage than other types of connectors. Other manufacturers, such as Dell, place a greater emphasis on the strength of their cables. Regardless of the type, the length of cable that connects the power adapter to the laptop will ultimately fail, which will be exacerbated by the fact that you will be using the portable PC on your laps most of the time.
  • If you have to twist the DC power cord or have to position it in a specific way in order for the laptop to charge, this indicates that the output cable on the inside has been broken or that the connector is faulty. Compared to the other two options, securing the DC output wire is significantly simpler.
  • After you’ve determined which portion is problematic, cut along the cable, being careful not to cut too close to the choke if you need to shave it. The choke only blocks RF interference caused by the laptop, which is a reasonable trade-off for the convenience it provides.
  • Following that, you’ll want to carefully peel off the outer plastic sheet from the two cords, leaving approximately an inch between them. Make a proper connection on consecutive wires using solder, braid, or connectors for the best results. Make sure the jointed wires do not contact each other by separating them with tape so that the connection does not become shorted.
  • If the problem is caused by a broken pin or a cable that has been cut too close to the connector, you will just need to replace the port or the DC cable, not the entire adapter, and the problem will be resolved.

Can I Charge My Laptop Through a USB Port?

No, you cannot charge your laptop through a USB port. The short answer is “no.” USB ports are typically used to distribute electricity to various devices, rather than the other way around.

However, there are some new laptops on the market that have a port that may be used to charge the machine as well as to connect to the internet. However, when it comes to charging, they are neither as fast or as dependable as regular ports are.

How Much Does It Cost to Fix a Laptop Charger Port?

Having knowledge of how to open your laptop’s charger port is required in order to replace the charger port on your laptop. In a different city, the labour rate for a laptop technician may be significantly more or lower. Look up how to disassemble your laptop model until you reach the motherboard if you want to avoid paying high charges.
The power port is soldered to the board, and you may find that it is loose or that it does not retain contact with the board. Look up the port on your laptop’s motherboard on the internet and solder it back onto the motherboard. The parts are inexpensive, but the same cannot be true for the cost of having a laptop’s technician service performed.


The charger for a laptop is made up of the primary AC power wire, an adaptor, and an outlet. To resolve any issues it may be experiencing, apply the same procedure you used to identify the source of the problem. Knowing which is which can save you hours of aggravation and hundreds of dollars in repair costs (sometimes in the hundreds of dollars).
