How To Fix a Charging Port on a Laptop In 6 Effective Methods

When you use modern gadgets today, in addition to knowing how to use them, you also need to know how to preserve them for long-term use. There are many different problems that can happen with your devices, especially laptops. If your laptop’s charging port is faulty, this guide will quickly guide you through how to fix a charging port on a laptop. We will help you narrow down where the problem lies and the most economical and effective solution.

Identify the problem

Before trying to find a fix, it is necessary to determine where the problem comes from causing the charging port to fail. It could be a faulty battery, a damaged power adapter, or a cut cable. First, check that the charger is applying the correct voltage by using a multimeter. Assuming the charger is working, then the problem lies with the laptop’s battery. If that’s the case, you’ll most likely have to replace the battery entirely.

In case the power adapter is not providing the correct voltage, then you can fix the problem by dealing with the faulty adapter. If there is no power from the adapter, it may have faulty cabling. Now let’s dive into how to fix a charging port on a laptop quickly and reasonably.

Handling faulty adapter

The converter connects to the mains via a plug, converting AC current to DC. As a result, you need to handle this electrical equipment carefully. If you are unable to take the necessary safety measures, purchase a replacement charger, which is usually available at your local laptop repair store, or visit an electrician to have it repaired.

You can fix the power adapter yourself if you take the proper safety precautions and have a basic understanding of how electrical circuits operate. First, disconnect the charger from the mains outlet and turn it off. The majority of laptop power adapters are kept in plastic boxes that are super-adhesively closed. If yours resembles mine, lay it flat and firmly pull the two pieces of plastic off. To break the seal, insert a thin knife or screwdriver between the two plastic pieces. After that, carefully remove the charger to reveal its inner workings.

Handling faulty adapter

The motherboard, which is made up of transistors and capacitors, is located inside. A bulging capacitor is a typical indicator of damaged adapters. By purchasing a replacement capacitor with the same capacity as the failed one, you can temporarily fix this small issue. To ensure that the cable is not damaged, use a voltmeter to test the cable’s continuity. When the adapter is connected to AC power, use extreme caution to avoid touching the PCB board. At this point, you can have a complete replacement if the DC cable outlet isn’t working properly. A laptop battery won’t charge if the positive and negative DC outlets are switched, therefore take care to avoid doing this.

Fixing the broken Charger Cable

Modern laptops have glowing LEDs in their charging cables. If that LED glows, it means your laptop is getting proper power. Most adapters have a long wire covered with insulating material, mostly rubber or plastic. You need to carefully cut the insulation with a sharp knife or cutter. Then pull the wire inside it to see where the real problem is.

Something as simple as a blown fuse, a bad plug, or a damaged wire could be the cause of the issue. Once you’ve identified the problematic component, carefully cut along the subsequent wire while still neatly wrapping the outer plastic, about an inch apart from the two wires. For the greatest results, utilize connectors rather than solder or braid to make the right connection on multiple wires at once. To avoid damaging the connection circuit, make sure the connected wires are kept apart from one another using tape.

Lose the Battery

Check battery integrity. If your laptop came with a removable battery, take it out and hold the power button for about 15 seconds to drain any remaining power from the device. Then plug in the power cable and turn on the computer with the battery removed. If the laptop powers on properly, it means the power adapter is working properly and the problem may be with a bad battery. Now take the device to a professional to have the battery replaced.

Check the Connector

When you plug in your laptop’s power connector, make sure it’s secure. If there is dust or another buildup inside the jack, it may not make a clean connection. Try cleaning the jack with a toothpick and plugging it back in. In more severe cases, you may find that the jack is wobbly or loose, which indicates that the power jack is damaged internally and that you need to take the computer to a shop for repair.

Check your Settings

Click the Additional Power Settings link after finding “Power & Sleep Settings” in the Start menu of Windows 10’s operating system. Click Change plan settings, then visually verify that everything is configured properly. Additionally, you can specify what should happen when the lid is closed or the power button is pressed, including sleep and shutdown. Even if the battery or charging cord is not physically damaged, it is simple to assume a power issue if these settings have been altered. Restoring the power configuration to its default settings is the simplest way to confirm that your installation isn’t creating issues.

Mac users can open System Preferences, then select Energy Saver, and review their preferences. Mac settings are adjusted with a slider, allowing you to choose how long the computer can stay idle until it goes to sleep. If this period is too short, you can suspect a battery issue during the installation as the real culprit.

Update the Drivers

Do a “Device Manager” search in the Start menu. Update Driver can be chosen by right-clicking on each item. Restart the laptop and plug it back in when all drivers have been updated. You can download the most recent drivers from the manufacturer’s website if this does not resolve the issue. In order to force Windows to reinstall the driver from scratch, you can also try to entirely delete the Microsoft ACPI Compliance Control Method Battery before rebooting. Now you have learned how to fix a charging port on a laptop, right?


A damaged laptop charging port can be very troublesome. If your laptop is not charged, you may not be able to use it. So it’s important to identify the problem as soon as possible and fix it so you can continue with your daily tasks with your laptop. Today we have shown you how to fix a charging port on a laptop with 6 simple methods. If still can not fix, like a sick person who consults a doctor, internal problems require a specialist. Contact your manufacturer or call your local computer repair shop.
