The power jack is a small board level part that provides a throughput for power to run and charge your laptop. It’s a small box that consists of a combination of metal, plastic and potentially wires depending on the design. There are two different types of charging ports on a laptop. The first type is a soldered on plug that attaches to the motherboard. The second is a cable style design (wire) that plugs directly into the notebook motherboard.

How do I know if my power jack is broken?
When your laptop is having power issues related to the jack they are usually pretty specific. For example, a common symptom of this power failure is the connection where you plug the tip of the ac adapter into your laptop feels very loose. The connection between to the two should feel solid and snug. If it feels loose then your charging port may be making a poor connection. Moreover, this loose connection is a problem with the dc jack not making proper contact to the motherboard or the cable style jack is simply broken. This can occur because the laptop cord was tripped on or stress was applied to the area where you plug the ac adapter in over time.
When the connection is bad you will also usually get a subset of symptoms. An example of this is the notebook going back and forth from battery to ac power. This is typically intermittent and can depend on the angle that you’re holding the plug in to make proper contact. It’s also possible that you’re getting some heat build up at the location of where you plug the ac adapter into the computer.
On the other hand I see customers laptops where they think the power port has gone bad but it’s actually a different type of failure. A common thing I see is when a laptop just dies suddenly and abruptly. The computer is working just fine one minute and the next it shuts off and won’t come back on. This is a typical motherboard failure symptom. When the power plug fails it will usually be a progressive and intermittent failure over time with the symptoms mentioned above barring the laptop taking a fall or someone tripping over the cord.

How do I fix my broken power jack?
Before you do anything, the laptop will need to be taken apart down to the motherboard. Below is a video of Pomeroy Computing performing a dc jack repair on an Asus motherboard. It had a physically broken charge port that requires soldering to remove and replace. If you’re looking into trying to fix it yourself you will need:
- Quality Soldering Iron (I use a Hakko FX888D)
- Flathead style soldering tip (seen in video) for your Hakko or equivalent iron.
- De-soldering Braid
- Flux
- Solder
The first step in a repair is to add solder and flux to the solder points of the broken jack. This will get the old solder flowing and easier to remove. Second, you use the de-soldering braid to remove all the new applied solder and existing old solder. When you have removed it from the through holes you can take off the old port. Next, you install the new jack onto the motherboard and add new solder to the through holes. If everything has been done correctly you will have a good connection to the motherboard and power is restored to the laptop.
How much does it cost to replace a power jack on a laptop?
The price to replace a bad jack ranges in price. I’ve seen it as low as $50 and up to $250+. The part itself costs anywhere from $5 up to $50. When you have a common make and model (ex. Dell 15 3000) the part is usually cheap. If you have a high end laptop and not many were made of that model it could have an expensive proprietary port. Pomeroy Computing charges $69 parts and labor on most laptop makes and models.
Can I bypass the dc jack and charge the notebook a different way?
Usually the answer is no. The charge port fulfills the power requirements for a laptop more than something like USB that has limited power. There are rare cases where a laptop can also be charged on the USB-C connection or the battery is removable and can be installed into external battery charger.
