So, what to do in such a situation? Don’t panic! We will share all the details of how to fix the laptop power jack without soldering

When you browse the internet and wander on websites, only a few are accurate and provide authentic methods. However, we will share all the methods after the hands-on experience with you, along with other necessary details in this article.

So, let’s begin!

What is a DC Jack For on a Laptop?

As every laptop works on electrical power and the stable electricity is provided with the help of a DC power jack. The DC jack has a special design, and it provides direct stable power to the laptop and also charges the battery inside it. It is just a smaller component less than the finger size, but it’s very important for the proper working of a laptop. If the DC power jack is faulty, your laptop will lose its functionality. 

How Does a Laptop’s Power Jack Work?

As mentioned above, the laptop’s DC jack is a smaller but necessary component of a laptop. The primary purpose of this jack is to provide smooth electrical power to the laptop. Further, it directly keeps the laptop ON with the power and also charges the battery inside it. 

Ordinarily, the majority of notebooks and laptops consist of two connectors internally. First, +ve & GND, and secondly, positive & negative connections. Remember that the older models’ power jacks are a bit different in appearance, but the overall working is the same. So, if you see a jack with a distinctive appearance, don’t panic. 

Overall, working is pretty simple and easy. One connection provides the power to turn ON the laptop, and the other two terminals charge the battery. Not to mention, some latest laptops add additional accessories to these connectors. Some laptops offer DC jack replacement without soldering or with soldering. It usually depends on the overall design of the manufacturing company. 

How to Know About the Power Jack Failure on a Laptop

Whenever your laptop is not charging, it does not mean there is a charging jack problem. You can say that it might be charging jack failure if it’s not charging. However, you don’t need to worry about it. We are always here to help you. We have listed some practical methods that will help you out to know about the DC jack failure:

  • Power Light Blinks

Generally, a proper power jack provides stable energy to your laptop, and the power light (if your laptop has it) remains ON. Check out the power light; if it’s turning ON and FF, you need to check the main power supply. Check whether the charging adapter is connected correctly to the AC power outlet or not. Make sure it is snug-tight; otherwise, it can cause sparking or any electrical damage. 

  • Battery Is Just Connected but Not Charging

If there is some issue with the battery and it’s not charging, there is some problem with the DC jack. If there is not an issue with the charging light, it might be a problem with the battery. You can check it easily by clicking on the charging icon on the bottom right corner of the laptop screen. 

Suppose the laptop is showing “Not Charging”, you need to check the adapter and jack whether they are supplying the steady power or not. Failure to the charging means the bypass laptop power jack is not supplying the true DC supply to the battery. 

  • The Jack Work on a Certain Charging Location

It’s a common sign that when the power jack of your laptop loosens, it only shows charging at a specific angle. For this, you need to tilt the power cord to start the laptop charging. It will create stress on the charging jack and start charging. You can say the power jack has broken inside the chassis. However, it might harm both the laptop and the power cord. If you face such a problem, fix it as soon as possible. We will tell you further about how to fix the loose dc jack. 

How to Test the Laptop Charging Port (Proven Methods)

Now, it’s time to test the laptop charging port. The primary tool to check any appliance is Multimeter (DMM), and we will also use it to test AC/DC power adapter. There is nothing wrong with the laptop but the charging jack. It is okay if the output voltages are slightly dropped. Check the voltages with DMM; if the voltages are dropped more, it’s time to repair the DC jack. 

Keep in mind that the adapter should deliver the exact rated voltage for proper charging. For this:

  1. You can check the rated voltages on the adapter and also the included manual. If the voltage is fine, now you have to check the DC jack. 
  2. Open the laptop lid and bring the DMM. Touch the positive terminal on the jack and touch the negative probe anywhere, i.e., chassis, VGA cable power, or anywhere you want. 
  3. After that, touch the positive pins with a positive probe and check the battery terminals one by one. 
  4. If they are bringing the current, it means there is a problem with the DC jack. Similarly, don’t forget to check whether the laptop jack is loose or not. 
  5. If yes, then the main problem is in the jack. So, these are some easy methods to test the charging port easily. 

Methods to Fix The Laptop Power Jack Issue Without Soldering

Some Essential Tools Before DC Jack Repairing

Whenever you go to fix the jack issue, I recommend you have some essential tools. It’s always better to gather all the tools before repairing them; otherwise, you will feel bothered. So, collect the following tools before repairing:

  1. Zip links 
  2. Electrical Tape (In case you don’t have the product at home, you can purchase it here)
  3. Wire cutter (In case you don’t have the product at home, you can purchase it here)
  4. Insulation remover (In case you don’t have the product at home, you can purchase it here)
  5. Buy an AC adapter generic package with all the attachments. 
  6. An empty barrel

Other Essential Electrical Repairing Tools

Here are some other essential electrical repairing tools that you must have:

If you have all the tools mentioned above, you can easily fix the DC jack within no time. Keep in mind that things get fixed quickly with the right tool available. 

1. Fixing Wobbly Power Jack

Fixing Wobbly Power Jack

If the power jack is working properly, but you notice that it’s wobbly, you need to fix it. There is a simple solution to fix this problem. In my opinion:

  1. You just need to buy some good-quality super glue, hot glue, or any premium-quality adhesive liquid. We are suggesting good quality because it will grab the jack properly. 
  2. After that, open the laptop by watching some helpful video and locate the power jack. 
  3. Open the glue and put it everywhere around the jack. It’s better to insert it on the bottom of the jack so that it can hold it perfectly. 

This is the easiest method and always checks the wobbly power jack after a few months. You can also test it easily while inserting the adapter pin inside it. It is better to fix it immediately; otherwise, it can cause any damage such as a short circuit, burning power cord, or any other electrical damage. 

2. Repair A Soldered Power Jack

Repair a Soldered Power Jack

If your laptop consists of a soldered power jack, you will find two types there. Some power jacks are soldered on the motherboard without any wires. Conversely, some laptop models come with a soldered DC jack with the help of short wires. So, our point of concern here is the soldered jack via wires. 

So, your task is to:

  1. Open the laptop and uphold the power jack. Unplug all the power supply coming to the laptop and also the charging wire. 
  2. Buy some good quality power jack by asking your laptop model in the market. You can easily get a new one with wires. 
  3. Further, remove the old jack if it offers to unplug, or you can cut the wires with the help of a cutter. 
  4. Attach the new power jack with the help of wires but make sure the terminals are attached correctly with each other. Don’t forget to tape the joints to prevent any electrical damage. 
  5. After that, just plug in the adapter without turning ON the laptop and check the voltages with the help of a multimeter. Match the voltages with the rated voltage; if all is fine, assemble the laptop again. 

Hence, your laptop is ready to use, and the problem has been fixed successfully. 

3. Physical Damage

Physical Damage

We have shared the method to replace the wobbly or damaged connections. However, there is no such cure if the charging jack has encountered physical damage such as burning out, broken pieces, and more. 

In such a situation:

  1. You need to replace the entire jack. You can do it by sticking it with some glue, but I don’t recommend such silly methods. 
  2. It’s better to replace the charging jack as a whole. You can easily find the new jack by searching it with the help of your laptop model. 
  3. You just have to remove the DC-IN of the power jack by disconnecting it from the body or motherboard. 
  4. You can easily do it by loosening the screws and replacing it with a new one. 

Congratulations, the power jack problem has been resolved.
