A DC power jack is present in every laptop, so your device accesses a stable electric current and permits you to charge the battery later. If there is an error in the DC power jack, your laptop will automatically run out of battery and not function properly. A laptop’s DC power jack comes into use logically often: if you daily use your laptop, and also use the power jack daily. Excessive irregular use of your device can destroy the DC power jack and cause it to fail.
Soldering is a process in which two or more items are joined together by the solder. In the past, nearly all soldiers had the lead, but for electronics and plumbing purposes, environmental and health concerns have increasingly dictated the use of lead-free alloys. In this article, you will learn how to fix a laptop power jack.
How to fix laptop power jack?
If your laptop doesn’t charge for tilting or rotating the charging pin or even detecting it, it’s due to the wrong connector, charger cable, or DC jack inside the laptop. But how do you know if this is a problem with your charger or laptops? You will find all the answers to your questions if you read this post.
Unluckily, this is usually not necessary because most of the laptops’ power jack is soldered directly to the motherboard, and you have to heat the soldering iron to fix it. This article is all about how to fix a laptop power jack. First, before going into the essential rebuild process, you require to know:
How to communicate with a Laptop’s Power Jack Charger?
In general, most laptop chargers work on these two signals: GND and +VE. On the other hand, some producers of Dell give an additional sensing pin and these negative and positive contacts. So, the laptop’s jack has three connections.

These DC-jacks have wires attached to the connector, which goes to the motherboard. In this case, there are some options to fix the laptop’s power jack without soldering. Now we begin the step-by-step rebuild process.
Step 1: Check your Laptop Adapter
How do we know that our laptop charger is not causing irritation but the DC jack? If the DC jack has been physically damaged, then no explanation is required to condemn him. However, it is easy to check your laptop adapter. First, check the output voltage by connecting your laptop charger to the mains. There is a big problem with your laptop if you are getting the right voltage.
Check what Problem you are having?
There are many articles just fixing a special one for laptop jacks, which can’t help everyone. Yes! Many problems are with DC jack; you have to recognize it and then fix it because they all have different solutions. For Example;
The inner pins of the jack are broken. The whole jack is harmed. The DC-in jack is creating some spark when connected. It is also getting hot. DC jack came out of the laptop. The motherboard track is burned out that connects the jack to the circuit. The pin of the laptop jack rotates on the motherboard when plugging the charger pin.

As you can see, the laptop DC jack can’t get a single answer about any rebuild/soldering method. We are discussing all the critical issues and their solutions individually; you can pick your Problem and fix it.
Problems related to physical damage:
If the whole jack or pin of your laptop jack is damaged, then there is no solution to fix it; it simply requires to be changed. A soft connection between the adapter pin and the DC jack does not give current flow and generates heat. This can harm the laptop charger pin or destroy the editor board for a long time, so you’d better change it. Now detach the DC-jack connector from the motherboard, and unfasten the screw to remove it from the body. If soldered directly to the jack board, remove it carefully and gently, as this can result in severe harm to the circuit tracks.
Problems related to the motherboard tracks, pins, and wires:
If the DC jack is OK and seems to be good physically, we can fix it to get the power back on our laptop.
Section 1: The DC in-jack has a separate connector for the motherboard
From the motherboard, remove the jack connector first and then connect the adapter to the DC jack. Now check the voltage on the facility jack connectors; there should be no voltage as awaited.
To fix this:
Step 1: Pick a harmed DC jack’s broken wire or disconnection, connect it properly, and sell it. You can also use them for boosting if you have heat shrink tubes.
Step 2: Test the voltage. The connection should be the same as you made it.
Step 3: Reconnect everything and set up the laptop.
Section 2: DC in jack is sold on the motherboard
It needs a bit of care in contrast to the above process, as we will work on the motherboard. So, what is the situation:
DC jack is spinning
This condition is due to dry soldering, and our constant strength makes it bad. Apply the flow to all the pins of the jack and re-solder it properly to fix it.
The motherboard track is burned out, or a pin is broken
As the damage can be seen physically, you require a few essential skills to rebuild, as an incorrect connection can make your laptop irreplaceable. To fix this, first, identify which track is burned, that is, is it a GND, +VE, or sensing signal? Then wire the jack pin directly to where the path is going.
Now to secure it from spoiling again, apply an epoxy mixture or hot glue. It gives a blanket joint to the motherboard and connects to the adapter by enabling it to resist back and forth situations.
Use a thick copper wire carefully to avoid burning, and do not let the glue go inside the DC connector.
