This guide will explain how to repair a failed or loose DC power jack on a laptop computer yourself.

Disclaimer: I’ve made these instructions only for people experienced with soldering and repairing computers. If you don’t feel comfortable doing this job, please do not open the laptop or you can permanently damage your computer. Take your laptop to a professional repair shop instead.
Use this repair guide at your own risk. :)


For this repair you’ll need the following tools.

1. Soldering iron or soldering station. I use Weller WES51 soldering station and for this job I set temperature to about 800-850°F.
2. I use high-tech rosin core silver-bearing solder from Radioshack with diameter 0.022″ ( Catalog #: 64-013 ). I think standard rosin core solder will work just fine.
3. Desoldering pump for removing solder around component leads. I use Edsyn Soldapullt pump, model DS 017.
4. 99% isopropyl alcohol and tooth brush for cleaning the motherboard from flux.
5. A new DC power jack.

Laptop DC power jack repair guide.

Laptop DC power jack

As you see on the following picture, the solder drop on the positive terminal looks different than on other three contacts. That’s where the problem is. The positive pin is not making a good contact with the motherboard and because of that power to the laptop cuts off when I move the power plug inside the power jack.
I’m going to desolder the power jack from the motherboard, clean contacts on both power jack and motherboard and then solder it back in place – this is the proper way fixing the power problem.

DC power jack bottom side

Start desoldering process with adding some new fresh solder to all three contacts. This will make old solder more flowable, easier to remove.

Removing solder

While heating one of the contacts, remove the solder from this contact using the desoldering pump. Repeat the same steps with all power jack contacts until you remove as much solder as possible.

Sucking extra solder

Grab the power jack and carefully try removing it from the motherboard. Most likely you will not be able to remove the power jack the first time because there will be some solder bridges left between the contacts and traces on the motherboard. Carefully wiggle the power jack without applying any significant force and at the same time heat up all contacts one by one. This will help you to remove the power jack.

Remove DC power jack

The DC power jack is almost removed from the motherboard.
Be careful. Inside the positive hole there is a copper sleeve which connects the terminal on one side of the motherboard with the traces on the other side. If you are removing the power jack with force, you can pull the sleeve from the hole. You don’t want to do that.

UPDATE: If you accidentally removed the internal sleeve, check out this post: How to fortify damaged power jack connection.

So, do not apply any force and make sure the solder is melted when you are removing the power jack. I hope you understand what I’m talking about.

Separating jack from motherboard

After the power jack is removed, clean all oxidized contacts with a knife.

Cleaning power jack contacts

Apply a fresh coat of solder to all contacts on the power jack.

Coating contacts

The power jack terminals will look dirty because of melted flux.

Flux on motherboard

You can remove the flux using the tooth brush and alcohol. It’s not necessary but it will make your job looking clean.

Removing extra flux

Apply a fresh coat of solder to all power jack terminals on both sides of the motherboard.

Coating contacts

This side has been coated.

Cleaned contacts side 1

And this side has been coated too.

Cleaned contacts side 2

Now you can install the power jack back on the motherboard. Put something under power jack so there is no gap between the jack and the motherboard. Now you are ready to solder the jack back in place.

The job is done and the laptop DC power jack is fixed. B-E-A-utiful!
Now just install the motherboard back into the laptop and you are done.

    I am attempting to remove a DC jack from a Gateway NV53. The solder in there doesn’t look anything like normal solder. I have tried desoldering with a vacumn and desoldering braid and still I can’t get the old solder out. I live in a remote area in SoCal and believe it or not I cannot find ANYONE with any electronic soldering experience to help me out. I obviously don’t want to spend alot on this or I’d just buy a new motherboard. Any ideas what I am doing wrong? It could be the iron isn’t hot enough, but I want to ask someone before I go buy another soldering iron.

    jojo,

    I googled for MSI 1684 and couldn’t find anything.
    Does your laptop have any other number, name? Take a look at the bottom sticker.
    Maybe MSI 1684 is not the model number. Search for any other numbers.

    Felix: your dv6810 has a power board. You can replace or resolder the jack, but it’s a pain. The pin layout is very different from other jacks, and the positive pin is very small. I’ve seen them burn out at that connection a few times.

    The light (the ring light) lights even if the motherboard is not getting power (such as when the positive pin is loose in it’s hole). It is easiest to replace the whole board – Hopefully “laptoprepairs101″ will have one. If not, then search eBay (you can get the part number for the board from HP’s Parts site).

    IF “laptopparts101″ has the board, ORDER FROM HIM!!!! I use him ALL THE TIME, for numerous jack repairs we do. He is ALWAYS my first choice for jacks and harnesses. If he doesnt have one, then try to find a reputable seller on eBay.

    Julia,

    I have a Toshiba satellite L35-s2316 that has the exact loose DC plug symptoms.

    In Toshiba Satellite L35 laptop the DC jack is NOT soldered to the motherboard. It’s attached to a power cable.
    If the DC jack goes bad, you simply unplug the old harness from the motherboard and replace it with a new one.
