How to Fix Laptop Power Jack without Soldering?

If your laptop is unresponsive when you try to charge it, your first instinct should be to check the connection between the computer and charger.

The wires inside of the power cord can fray or break over time. You can test their condition by simply wiggling them to see if this solves the problem.

It’s also very possible that there are small pieces of metal stuck inside of your charger port due to damaged pieces of plastic where the wire meets the laptop.

The best way to solve this problem is by calling customer service or attempting to take apart your laptop charger at home (with extreme care) in order to ensure that there aren’t any foreign objects left behind which could cause further damage.

So, let us discuss in this article how to fix laptop power jack without soldering.

How Power Jack Works?

Many laptops have DC power jacks, which are necessary for charging your laptop. The working principle of DC power jacks is pretty simple – the DC voltage is converted into the AC voltage that is then supplied to your device.

The real challenge lies in finding problems that can negatively affect this process. It’s possible that there are some jams within the jack itself, which, in turn, may damage your laptop’s charging port or even prevent it from being charged altogether.

Many laptops will usually charge when you connect them to an electrical outlet, plugging in the device’s power cable. With many different devices around us, however, it may be easy to misplace your charging cord or leave it plugged in near water.

If this is the case with your laptop charger, the problem may lie with its port. Dell features a stunningly smaller connector so securely affixes inside of your machine’s power jack.

These finer grooves ensure a steady connection while being significantly sturdier than most connectors of the same size. Because of their finer design and ease of use, these pins are easily susceptible to damage especially if they’re damaged by something like solder – which you should stay away from.

Fixing the Laptop Power Jack Without Soldering

Here we will discuss how to fix laptop power jack without soldering. For this purpose, different things are required. So, you have to follow the step-by-step guide to get your answer.

Equipment’s Required

If you want to learn how to fix a laptop power cord, first take stock of your resources. The first things you will need are some wire cutters as well as a small Phillips head screwdriver.

You’ll also need a soldering iron and solder as well as a hot glue gun and some silicone sealant. For this job, it’s best if the pointer is still working on your laptop so you can use it to gauge where the wires go.

If the adaptor isn’t providing enough power to your laptop, you can remove it from your PC or laptop housing by unscrewing it with either the screwdriver or pliers if necessary.

Once that is removed, you’ll see several colored wires coming out of the main power jack located at the top portion of your adapter plug.

Fixing Motherboard, Wire, and Pin related Issues

The DC jack is the part of the computer that allows you to plug in any device it supports. If it doesn’t work, getting power to your device won’t be possible.

The cause of this problem can be either because it’s not compatible with your computer or there’s something wrong with the cable itself. Two different ways are used to resolve this issue.

Motherboard with a separate Connector on the DC-In Jack.

Make sure you’re getting the adapter power plugged in and unplugged when needed. Make sure it is not too tight or loose. You will need to make sure if any jack has been plugged in and you’ll also need to make sure that your power adapter is at least rated for your machine.

Now make sure to check out all of your attachments and once again make sure there is no looseness and things are properly secured.

Once everything passes these tests you should be able to rule out a faulty adapter or not enough electricity getting into the system to run the components smoothly.

If it’s no longer an issue after restarting then another potential issue would be something like having a lack of RAM rather than getting stuck with a faulty Power Supply Unit (PSU) so please sit back, find some other ways to spend your time while we work on this problem for you.

Disconnect the computer’s power adapter jack from the motherboard. Attach the power adapter to the DC jack. Check the voltage on the DC jack.

Then plug it back into the PC and check again to make sure it has not come loose. If all is well, replace any cooling fluid previously drained and power up your computer.

Soldered DC-In Jack on the Motherboard

There are several common questions surrounding this issue that people always ask about, but the reason it exists is that there are two ways to fix a laptop power socket depending on what has gone wrong with it – soldering or using an alternative method of repairing things called dry welding.

The importance of ensuring the area is free from dust cannot be stressed enough because if your computer isn’t clean, it will only get worse over time which could potentially cause serious damage or malfunction once things have gathered together inside where they should not have been placed.

The solder or traces that connect the connection pins to the board burn out and cause the machine not to function. To resolve this issue, first, determine which track burned: was it the positive (red) or negative (black)?

If it’s red, you will change your wiring methods directly from the jack slot to where either track would reach. Or if it’s black, you can ignore both options and go directly from the jack slot to where either track would reach without burning another trace.

To protect against additional damage, attach a wire via glue or conductive epoxy mixture. Once attached to your board, this provides a robust link to your motherboard.

Common Symptoms of Power Jack Failure

The Power Light Turns on and off

A properly functioning DC power jack will ensure that you keep your power flowing steadily. You might think that if you find yourself having to jiggle your chord in order to get a charge it’s not working, but the only issue there is your cord.

However, if you’re experiencing flickering lights or frequent power cuts, you need to make sure that there are no loose connections in the socket because sparks could fly.

Uncharged battery

If your battery isn’t charging or if its charge is fading fast, it may be due to a faulty DC power jack. Most modern laptops use the latest version of this port which means that they can charge up quickly – even when being powered through an adapter.

The only way you can tell if it’s not working properly is by trying to charge your laptop after you’ve booted up.

It may display certain symptoms during this process, including ones associated with charging nodes wearing away over time using older style ports.

Loose power jack

It is an indicator of impending danger. When your laptop’s DC power jack becomes loose, it may not fit properly or change location. As a result, you may need to slant your power cord in order to get a charge.

This will stress your power cord and DC jack, potentially causing harm to both. It is important to resolve these issues before they become worse because if something like this happens, it can end up costing you even more money than what you owe on the original services contract for example that you might already have.


What is the best way to solder the dc power jack?

Soldering a DC jack to a motherboard is a simple process. Before soldering, place the DC jack in one of the allotted slots on the motherboard and add-flux for added security.
The next step requires using molten solder wire; for each pin, attach it directly to the pinhole on the motherboard.

Can a laptop power cord be repaired?

Cables always fray, and it seems like such a waste when an expensive new laptop charger might not make it past the first few weeks of use and then they break never to be used again.
Luckily this is one problem that can be fixed by Sugru Mouldable Glue so long as the core wire isn’t exposed and the outer casing has not been damaged.


There are different types of power ports on laptops and these ports can become loose and cause intermittent or even complete failure of the charging circuit.

Because many times the computer is still functional it’s easy to think one needs to replace the motherboard, but if one is diligent about properly diagnosing the problem, they’ll find that only replacing the power jack may be all that is required.

We’ve outlined a few ways to diagnose and address broken laptop power jacks. I hope that after reading this guide you will understand that how to fix laptop power jack without soldering.
