How To Fix Laptop Power Jack Without Soldering (Guide)

Laptops are a great way to stay productive while on the go, but what happens when the power jack becomes damaged and stops working? It can be a huge problem, especially if you need your laptop for work or school. This guide will show you how to fix a laptop power jack without soldering. It is an excellent solution for people who are not comfortable with using a soldering iron. All you need is a few simple tools and some patience! Let’s get started.

Check Whether Your Laptop Battery Is Operating

Never fear if you’re unsure how to check whether your laptop battery is operating. It’s pretty simple. All you need to do is open up your laptop and locate the battery indicator. It is usually a tiny light that is located near the power button. Once you have found the battery indicator, press the button.

If the light turns on, your battery is working correctly, and if the light does not turn on, you may need to replace your battery. However, it’s always a good idea to consult a professional before taking action.

Look At The Battery Life Through CMD

Using Windows, you can look at your battery life through the Command Prompt. To do so, follow these steps:

  • Press the Windows key + R to open the Run dialog box.
  • Type cmd and press Enter to open the Command Prompt.
  • Type powercfg energy and press Enter. It will generate an HTML report showing your battery usage over the last three days and your estimated remaining battery life.
  • Double-click on the battery Report to open it in your default web browser.
  • Look under the “Battery life estimates” section for your estimated usage and remaining battery life. Remember that this is only an estimate, and your actual battery life may vary depending on factors such as screen brightness, applications running in the background, and whether or not you’re using power-saving mode.

Test Your Power Adapter

If you want to test your power adapter to see if it is working correctly, there are a few things that you can do. First, check to see if the light on the adapter is lit. If the light is not lit, the adapter is not receiving power and needs to be replaced.

Second, test the adapter by plugging it into a known working outlet and plugging a device into the adapter. If the device does not turn on or charges slowly, the adapter is not working correctly and must be replaced.

Finally, test the adapter by plugging it into an outlet and using a multimeter to test the voltage output of the adapter. If the voltage output is not within the specified range for your device, then the adapter is not working correctly and needs to be replaced. Ensure it is well-connected to the docking station first.

If the outlet is working, check to see if the adapter cord is securely plugged into the power outlet and your laptop. Suppose, the cord is not plugged in correctly, you must replug it. If the cord is plugged in correctly and the adapter light still does not come on, you will need to replace the adapter.

Test The DC-In Jack

The most important part of testing the DC jack is checking that it provides power to the test unit. To do this, first, connect the positive lead of the multimeter to the tip of the jack, then connect the negative lead of the multimeter to the ground point on the test unit.

Next, set the multimeter to measure DC voltage and plug in the AC adapter. The dc power jack functions correctly if the multimeter displays a reading of approximately 12 volts. However, if no voltage is displayed, there may be a problem with the jack itself or the AC adapter. In either case, further troubleshooting will be necessary.

Finally, once you have verified that your laptop’s power jack is providing power, you can test for continuity by setting the multimeter to measure resistance. With the positive lead still connected to the jack’s tip, touch the negative lead to each pin on the jack. There should be continuity between each pin and ground. If there is an open circuit between the pins and the ground, then you’ll need to replace that particular pin of the damaged power.

Open Your Laptop’s Case

To open your laptop case, start by seeking out the seam that runs along the back or side of the case. Depending on the model of your laptop, this seam may be hidden by a strip of decorative trim. Gently pry up this trim with your fingers to reveal the seam beneath.

Once you’ve found the seam, insert a thin, flat object (such as a putty knife or butter knife) into the gap and gently pry open the case. Be careful not to apply too much force, as you could damage the case or your laptop’s internals. If the case is stuck or resistant to opening, try wiggling the blade back and forth to loosen it.

Once you’ve pried open the case, you should be able to lift it off of your laptop and see the inner workings of your laptop, including the keyboard, motherboard, and LCD screen.

The power jack is usually located on the motherboard near the AC adapter plugs in. In most cases, it’s clearly labeled “PWR” or “DC IN.” If you’re having trouble finding it, consult your laptop’s manual or look for a diagram of your laptop’s internals online.

Once you’ve found the faulty power jack, visually inspect it for any signs of damage, such as cracks, burns, or melted plastic. If there is any visible damage to the jack, then it will need to be fixed.

Reassemble Your Laptop And Reconnect It

If you’ve ever had a broken laptop power jack, you know it’s not a fun task. The good news is that it’s relatively easy to fix, and you don’t need to be soldering. Here’s a step-by-step guide on fixing a laptop power jack without soldering.

  • First, you’ll need to reassemble your laptop and reconnect it to the motherboard. After that, following your laptop’s manual instructions is usually pretty straightforward.
  • Next, you’ll need to locate the power jack on the motherboard. It’s usually located near the center of the board.
  • Once you’ve located the power jack, could you remove it from the motherboard? Of course, but again, be careful not to damage any other components.
  • Now, look at the power jack and see if there are any obvious signs of damage. If damaged, reattach the power jack by applying pressure to the tabs on the sides of the jack. Next, reattach the power cord to your laptop and plug it into an outlet to test the connection. If everything is working correctly, you should see the charging light come on.
  • If the power jack looks okay, you must reattach it to the motherboard and screw it. Again, make sure that it’s tight – you don’t want it coming loose again.


Broken laptop power jacks are no fun, but they’re relatively easy to fix. In most cases, you won’t even need to solder. Just follow the steps in this guide, and you’ll have your laptop up and running in no time. However, sometimes this might be an indication you need a new laptop.
