How Can Your Laptop Power Jack be Repaired Without Soldering?

You can repair power cord without soldering, but it relies on the dc power jack connection, and it is possible if you connect the laptop dc jack through the wire. However, if the jack soldered onto the motherboard directly, it is impossible. Also, you people can’t fix a broken or loose laptop power jack, don’t panic, and there is no need for a professional electrician; you can do it yourself. There are simple steps that anyone can follow.

How Can The Power Jack Work on Your Laptop?

DC Power is an important factor in a laptop as it keeps the laptop on and gives electricity to run. Primarily, laptops offer two connectors, including GND(Ground) and +VE, also known as negative and positive connectors. If the DC jack comes with wires, there is little chance of it’s fixing without soldering. And if the DC jack has no cables, when it is soldered directly into the motherboard, there is no change to prevent soldering.

Four Causes of Failures in DC Jack:

  • The reason is the reinforcement within the motherboard and casing structure. Hence, when plugged in the jack, it can’t handle stress.
  • In case of extensive usage, by the time some part starts to lose.
  • It also happens while vacuum cleaning when you carelessly clean, sometimes the charger drops down, and its plug jerks.
  • In a dc jack laptop, DC jacks are not correctly soldered.

How You Can Find Failures in Power Jack:

There are few indications of the failure of the power jack, and its primary function is to deliver power consistently. When it fails to do that, it means there is a problem. Other ways to check failures are:

  1. Flickering of power light shows the on/off charging. It is because of a broken jack, and it switches intermittently from battery power to AC Adapter.
  2. When there is a need to wriggle the cable to fix it in the power socket, keep in mind your jack has some problem
  3. If your laptop charger is at an angle, Jack has a problem, not the laptop and battery. It’s a problematic situation never to use a laptop in this case because it may harm your laptop.
  4. In this case, sometimes, the laptop fails to run with an adapter.
  5. Suddenly the laptop shuts down.
  6. While inserting the adapter here, you will see sparks.
  7. The laptop stops to get power or get power at a specific cord.

How Do You Check The Failure in The Power Jack?

Before thinking about soldering laptop power jack, first, it is good to observe the problem and learn how the power jack repairs, then move towards other options. What to do to solve this situation? Follow the steps:

Check Power Jack With Multimeter
  1. Test power adapter by the multimeter. If they’re a bit different in voltage, it’s ok. But if the voltage is above 1 amp, it means there is a problem. Numerous people do not know their laptop’s voltage, so first, turn on the computer and see the sticker; here, you will find every detail of specs about the laptop. Voltage above or below 1 amp is dangerous for the laptop.
  2. Now make sure that your adapter is OK, then check if your power jack is faulty or not? For this purpose, turn the laptop, take the battery out, plug in the charger, and put a glimpse on VGA ports and other ports. Then again, take a  multimeter, press its negative probe, then connect the positive probe of the battery’s pin. The higher reading tells about fried motherboards, and if you see no task, it implies the jack might be defective. 
  3. Eventually, check the jack connector. Have a site on the connector that is connected with the motherboard pull it out. In the next step for the power supply, connect the adapter to the DC jack. Take the multimeter to check voltage; it shows no recording if your connector is defective. Moreover, for continuity, you can also identify the jack point; it includes four outer pins, the main pin, and the middle pin.

How Can I Observe The Exact Problem of The Power Jack?

It’s a major problem to repair laptop power jack in a power jack laptop if the laptop loses the power carrying capacity or if the power jack becomes loose. First, it is crucial to examine whether it occurs due to an injured power jack, loose power jack, and another problem.

For cord preparation, there is a need for cutting the laptop’s cord because, in this situation, we are handling generic and laptop ac adapters.

Generic AC Adapter:

  1. To desire length, cut the generic but keep in mind, the cord length should be enough long that it can use for other purposes
  2. Insert this cut cord in the barrel
  3. By stripping, wires are exposed

Laptop AC Adapter:

  1. Reduce the cord length for proper replacement
  2. Place the section of tip and place the cord
  3. Make sure that the exposure stripping wires

Cord Joining:

It’s the most crucial step in this to ensure the use of a multimeter for right use of wires.

  1. Connect the laptop and AC adapter and prevent contact between them. Also, check the negative and positive wires.
  2. Through generic and plug, you can test wires that have a little bit of connection with both the inner and outer plug connections.
  3. By wrapping tape around the last wires, protecting them, and with the help of video, join the inner.

After doing the given steps, carefully check to make sure that the barrel is sealed or not completely. Now add zip ties for protecting wires from losing; also, these zip ties protect the cables from disconnecting.
