How To Fix The Laptop Power Jack Without Soldering: Easy way to repair

  1. Reattach the power jack while applying pressure.
  2. Attach heat shrinking tubes as reinforcement.
  3. Recheck the voltage, and it should appear.
  4. Reconnect and reassemble the laptop.

If you find your laptop charger is not working when it is bent or when rotated, the problem could be in the cable itself, the connector, or even the dc jack.

If you find that your laptop isn’t charging at all it’s generally easier to replace the entire cord rather than attempting to repair only a part of it.

Moreover, damaged DC jacks are not required to be proofed. Laptop chargers have very simple outputs, which can be checked easily. Ensure the output voltage lines up with the laptops by plugging it into a power source.

Problem Relating to the Physical Damage

It is not possible to repair or replace a damaged laptop charger jack pin, only to replace the entire device.

There may even be suggestions to stick it, but I do not recommend it. In a loose connection, a replacement charger can’t deliver a constant current. Using the laptop for a long time can lead to damage to the motherboard or the charger plug pins.

When you want to disconnect the adapter from the motherboard, unscrew the screws located on the DC-IN jack and remove it.

However, be careful not to unplug any wiring otherwise this could cause damage to the board causing your computer not to start up properly.

This kind of repair requires certain skill sets and is beyond most people’s expertise. If the connection between your speakers and your motherboard has been burned, you’ll need to solder the track wires directly from the jack pins in the speaker directly to the track on your motherboard itself.

Using hot glue or epoxy is effective in preventing the damage from recurring. Connecting the adapter to the motherboard ensures a rugged connection between the components. To avoid burning, use a thick copper cable and prevent any adhesive from entering the DC-IN connector.

Dc-in Jack Has A Separate Connector For The Motherboard

To connect the adapter to the AC jack, you must first disconnect the connector of the jack from the motherboard. Make sure that the voltage is not at the expected level on the power jack.

To correct this, it’s important to find the faulty wiring, which you can trace using a multimeter. Check the DC jack connector where the terminal has now been properly soldered and attached.

You can also protect your device with heat shrink tubing to prevent any future wiring issues in this location.

Now reconnect the system, and see if there’s an improvement with your laptop’s battery. Put everything back together by placing all components in their proper location on or inside your PC or device housing cover.
