If your laptop detects charging only by rotating the charging pin or bending it to one side or not even detecting it at all, it may cause by a malfunction of the charger cable, connector, or dc jack (inside the laptop). Now, do you want to how to fix laptop power jack without soldering?
But how do you know if this problem occurs with a laptop or charger? If you read this article, you will get answers to all your questions and the solution to your question about how to fix laptop power jack without soldering?
If the DC jack is physically damaged, no proof of guilt is required. However, checking the adapter of a laptop is very simple. First, connect the laptop charger to a power source and check the output voltage; it should be the same as the print on the charger body.
If you get the right voltage, it is most likely a problem with your laptop. However, this is not a completely reliable test, and your laptop charger works 100% right.
I know that you have landed on this page and know how to fix the laptop power jack without soldering. Unfortunately, this is not possible in most cases, because most power jacks for laptops are soldered directly to the motherboard, and to secure it, you must preheat a soldering iron.
The power jack is the port where your laptop connects to its charger, and if it’s faulty or broken for some reason, you may need to replace it with a new one. However, if you’re not an expert in soldering (or don’t want to risk damaging other parts of your device), there are still ways that you can solve the problem without having to order more parts online.
Your laptop is your lifeline, but what happens when it’s not working? You can’t just leave it in the corner and hope that someday you’ll get around to fixing it. If you want a quick fix without having to order parts or pay for expensive repairs, then this blog post is for you. In this post, we will show how to fix a laptop power jack without soldering.
We will also give you some tips on preventing future problems with your computer so that you don’t have an issue again! Let’s get started!
How Charger Communicate with Laptop Power Jack
Generally, most laptop chargers work on two signals: + VE and GND. On the other hand, some manufacturers (such as Dell) provide additional sense pins in addition to these positive and negative connectors. Therefore, there are three connections in the laptop jack.
Identify the Actual problem
I have read many articles that only show specific fixes for laptop jacks and cannot help everyone. Yes! DC jacks can encounter many types of problems, and you must identify and fix them before they all have different solutions:
- The internal pins of the power jack are damaged.
- The entire jack is damaged.
- When connected, the DC-in jack is generating some sparks and getting hot.
- The DC jack came out of the laptop.
- The motherboard track connecting the jack to the circuit burned.
- When the charger’s pins are connected, pins of the laptop jack shake on the motherboard, and so on.
As you can see, there is no answer on how to repair a laptop DC jack with/without soldering. I will list all the major problems and their solutions one by one, and you can identify and solve the problems.
Tool Required to Fix Laptop Power Jack
If you want to know how to fix the laptop power jack, then you required all or a few (depend on your problem) following tools for the laptop dc jack repair.
- Universal AC adapter package with accessories. Make sure all accessories are compatible with your laptop in terms of size and related factors.
- Communication tools for laptops:
- Some zipper
- Wire stripper
- Empty sharpy bucket / empty highlighter bucket. If the tag is still working, don’t waste it and don’t improvise this part.
- Electrical tape
- Hole puncher – you can choose a screw and screwdriver combination/nail, hammer and drill combination/laser (as long as it can hold the barrel)
Problem Relating to Physical Damage
As mentioned above, if the pin or the entire jack of your laptop jack is damaged, there is no solution, just replace it. Some might even suggest sticking it or anything else: I don’t recommend it. A laptop charger port loose connection will not provide a constant current and generate heat. Using it for a long time may damage the charger pins of the laptop and even the motherboard, so it is best to replace it.
You can use this search query “[your laptop model] dc jack” to find a dc-in jack for your laptop.
Now, disconnect the connector of the DC-IN jack from the motherboard and loosen the screw to remove it from the body. If the jack is soldered directly to the board, remove it carefully and lightly as it may severely damage the circuit wiring.
If the DC jack is okay and physically looks good, then I can fix it to bring power back into the laptop. There are two methods to correct the problem.
1. DC-IN JACK SOLDERED ON THE MOTHERBOARD
Now you want to know how the laptop power jack repair. Your particular attention is needed because you are going to work on the motherboard for replacing the power jack on a laptop. So, the situation is critical.
This situation is caused by dry welding, and our continuous force makes the situation worse. To secure it, apply flux to all the pins of the jack and solder again correctly.
You need some advanced skills for this repair, because the wrong connection may make your laptop unrepairable. To fix the problem, first, find out which track burned, that is, +VE, GND, or inductive signal. Then, solder the wires directly from the jack pins to where the track will reach.
Now, avoid damaging it again, use hot glue or any epoxy mixture. It provides a rugged connection to the motherboard and makes it able to withstand the movements when connected to the adapter.
Note: Remember to use thick copper wire to avoid burning, and do not let the adhesive inside the DC-IN connector enter.
2. DC-IN JACK HAS A SEPARATE CONNECTOR FOR THE MOTHERBOARD
First, unplug the connector of the jack from the motherboard, and then connect the adapter to the DC jack. Now check the voltage on the power jack connector; it should not have the expected voltage.
To fix it, find the broken wire or the disconnect pin of the DC jack, now properly connected and soldered. If you have heat shrink tubing, you can also use them for reinforcement. Recheck the voltage; it should be there once the connection is established. Reconnect all components and assemble the laptop.
I hope the above tips and solution steps can help you in many ways, and you know very well how to fix a laptop power jack without soldering. When I first got stuck on this particular question, I put a lot of effort into finding the answer to the problem.
However, after reading my article, you will be able to solve the problem with a small amount of welding and a low price.

Questions and Answers
My Laptop is Plugged in but not Charging, What I do?
Usually, this problem occurs due to a battery pack failure. Remove the battery from your laptop and use only the AC adapter to turn it on; if it goes well, it may be time to replace the laptop battery.
How Can I Solder the DC Power Jack?
The soldering process is more comfortable than removing the DC jack, especially when soldering it directly to the motherboard. To fasten the DC jack, place it in a pinhole on the motherboard and apply flux. Now, use molten solder wire to solder all its pins one by one to the motherboard connection.
What I Do If my Laptop has a DC Jack with a motherboard connector?
If your laptop has a DC jack with a motherboard connector, it’s relatively simple. You must plug the connector into the motherboard and tighten the DC jack as before.
Can I charge my laptop with any available charger?
No, you should not do this; it will damage the adapter or laptop. If the power rating of the adapter is lower than the power of the computer, when you increase the load on the computer, the power of the adapter may suddenly increase instead of immediately. When the charger is rated higher, it may burn out the laptop’s circuit.
However, in most cases, you won’t find chargers with the same pin size and different ratings, but not without them.
Can I know if my Charging Port is damaged?
Sometimes it can be seen from the outside. If your laptop’s charging pin is not correctly inserted into the DC jack or if the centre pin is damaged (if present), or if it swings, the laptop’s charger port is more likely to be damaged. For a thorough inspection, you must disassemble your laptop. If you want to know how to fix the laptop charger port, then please mention it in the comment.
