How To Fix A Laptop’s Power Jack Without Soldering?

Last updated Jul 15, 2021

Laptop power jack not working properly is any laptop owner’s worst nightmare. Your laptop is absolutely useless if it doesn’t have access to power, and life without a laptop in the 21st-century is inconceivable.

So what are some common problems that can affect your power jack, and is it possible to fix them without the use of a soldering iron? Keep reading to find out.

Can it be done?

There are many reasons your laptop can stop charging. It may be due to a faulty connector, faulty charger cable, or the DC jack (situated inside your laptop). But how do you know what is at fault here? Is it the laptop’s fault, or is it because of the charger?

The vast majority of laptops have their power jacks directly soldered onto the motherboard, so, unfortunately, it may not be possible to fix the faulty one without a soldering iron. Typically the vast majority of chargers use two signals GND and +VE, but there are some manufacturers (Dell, for example) that have an extra pin, so there are actually three connections in the track.

The first thing you need to do is to check your laptop adapter. This is to make sure that it is the one at fault and not the port. Checking if the adapter works is quite easy. You can check the output voltage of the charger by connecting it to the main.

The output voltage should be the same one that is printed on the body of the charger. This doesn’t necessarily mean that your charger is 100% off the hook, but if the voltage is all right, it is highly likely that the problem is with the jack.

Of course, in some cases, it is obvious what’s wrong, for example, you may have dropped the laptop, and you can see that the DC jack has visible physical damage.

Different types of problems your laptop jack may have. In order to fix your jack properly, first, you have to identify the exact nature of the problem. There are several things that may affect the functionality of the charging jack.

For example, the internal pin may be damaged, or the entire jack may be damaged. The DC jack may be getting hot when connected or even might be generating some sparks. The jack may also come out of the laptop, the motherboard track that connects the circuit with the jack may be burned, or the pins on the motherboard which connect it to the charger may be wobbling.

If your laptop track has been damaged, then I’m afraid it will need to be replaced; it just cannot be fixed. Your friends may suggest you just glue it up to make it last longer; however, that is not recommended.

If the connection between the adapter and the jack is loose and there is no constant flow of current, it may overheat and damage the motherboard over a long period of time. And this is a much more expensive problem to fix.

You can purchase a compatible jack online by simply typing in your laptop model number. If you see that the jack’s been soldered onto the board directly, make sure to remove it as carefully as possible; otherwise, you may damage the circuit tracks.

If your motherboard has a separate connector for the DC-in jack, then, first of all, you will need to disconnect the jack from the motherboard; then connect your adapter to the track. Next, you need to check the voltage on the power jack connectors.

You shouldn’t be able to see any signs of voltage. You fix it by locating the damaged wire or the pin of the jack that has been disconnected. After you have reestablished the connection, the voltage should be there. Put everything back in its place and reassemble the laptop.

If the jack has been soldered directly onto the motherboard, you will need to proceed with caution. If the jack is wobbly, which may be caused by dry soldiering, you may be able to fix it by applying the flux on pins. After this, you need to solder it back into place.

If a pin is damaged or the motherboard track has been burned, then you will need to have some advanced skills to fix this problem; otherwise, you may cause permanent damage to your laptop. If you’re unsure of your skills, it is always best to entrust a professional with such complex repairs.

Some more questions and answers regarding the laptop DC jack.

How can you tell that the laptop charger port is broken?

In extreme cases, you can see that the port has been broken by examining your laptop from the outside. There is a high chance your port is broken if your charging pin does not fit inside correctly or if it is wobbling.

How can you solder the power jack?

Removing the jack is usually more difficult than soldering it back into place. To do the soldering, you need to place the jack inside the pinholes that exist on the motherboard. After this, you can solder the pins onto the motherboard one by one with some melted soldering wire.

What to do if your laptop is plugged in but is not charging?

In most cases, this problem happens because the battery pack is faulty. Try removing the battery from your notebook and powering your laptop by using only the AC adapter. If it worked, this is a sign that it is time to change your laptop battery.

Can I use a different charger with my laptop?

You shouldn’t use a different brand charger with your laptop because it can damage the adapter or even damage the laptop itself. If the power rating on the adapter is higher than that of your laptop, the adapter will burn out the circuit. If the power rating is lower, this also doesn’t bode well for the well-being of your laptop over a long period of time.

Can I use my laptop while it is charging?

It is generally OK to keep using the laptop while it is connected to the charger. Once it fully charges, it will switch to the adapter power automatically.

My charger is broken. How can I find the identical one for my laptop?

Your laptop model number is usually written on the sticker, which you can find on the bottom of your computer. You can search for the charger that has the same model number, and the same manufacturer as your laptop. You should also pay attention to the wattage rating and see whether the connector type matches your laptop.
