Laptop dc power jack plugs

This guide will explain how to repair a failed or loose DC power jack on a laptop computer yourself. As you see on the following picture, the solder drop on the positive terminal looks different than on other three contacts.
While heating one of the contacts, remove the solder from this contact using the desoldering pump. So, do not apply any force and make sure the solder is melted when you are removing the power jack.
While looking at it, and wiggling the power connector, I noticed the front lights flickering. Using your directions, Toshiba A75-s226: I was able to take it apart, reflow the solder: made it slightly beefier, and repair it! I have this power problem with my Toshiba Satellite P20 & will try to permanently repair my problem. Now that I know how to take the laptop apart, I am going to attempt to replace the power pin with a piece of flexible wire so that the problem does not happen again. I think the original cause was the flexing of the power pin & breaking away from the mother board when the power cord is flexing during usage.
Some of Dell’s laptops look for a proprietary signal from the power supply sent through a 3rd pin. Does anyone have an idea as to how I can clear those holes so that I can reinsert a power jack?
Do you think getting a smaller tip for my solder will hel with getting the excess that has filled the holes?
I would really really appreciate it if anybody could give me a guide on how to dismantle my laptop and get access to the DC power jack. Pick up your phone book and find a local computer shop (NOT a box store, but a shop that does real repairs).
Taking apart the notebook was a bit of a hassle though I got it all apart, bought a solder iron and solder and a magnifying glass and seen that the back pin wasn’t making a good connection with the motherboard. I’ve got a Toshiba Satellite A35 series laptop that needs a new USB port (one of the two ports broke). Do you have to go through all 25 step of disassembly to perform the power plug replacement? When I plug my power adapter in, the light on the front of the laptop comes on for a second then shuts off. Assemble everything on your desk, connect an external monitor, plug in the power adapter and turn on the laptop. I tried to google for PCG-GX600 and the only one site pops up, it’s my site with your comment. I am going to find some new plug replacements and try again though, waiting for the mail man so to speak. As soon as I turn ON the notebook, and the external power is connected, the notebook switch automatically over to battery power. The problem appeared when an other external power supply adapter (not from asus) was connected. I have a compaq presario R3000 and have a power jack issue and it seems that it just becomes unsoldered everytime i repair it although i’ve never cleaned the surface after removing the jack.

Apply some fresh solder on the hole, heat it up with the soldering gun and suck out the solder with the sucker.
If external monitor works fine but you have no video on the internal LCD, check the video cable connection on the motherboard, make sure the cable is properly connected to the motherboard. Not all HP manuals have laptop disassembly instructions, I believe only newer models have it.
Brian, you should be able to check continuity through the input jack that connects to the mobo..
I have a Dell Inspiron and had the original ac power supply burn out on it (no green light on the box, nothing on the voltometer) and found a third party adaptor that worked for charging. Your use of this website constitutes acknowledgement and acceptance of our Terms & Conditions.

Repeat the same steps with all power jack contacts until you remove as much solder as possible.
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.
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. My short term fix was to heat the power pin from the jack to the motherboard to repair the solder connection.
I have been Googling for a site like this for hours for instructions to do it on my own and here it is!
Do not try installing the power jack at this time, just add some solder so the hole is filled up with the solder. Find your laptop and download the maintenance and service guide, you’ll find step-by-step disassembly instructions in there. Even more recently, the adaptor was knocked loose on the corner of the desk and the power pin broke completely.
If the power button is located on a separate board, then you’ll have to connect this board too.
I’ll be using this over the weekend to try and repair my sad little Dell Inspiron 2200.
It took me a little over an hour to do it, but then again, this thing has been apart 7 times now.
The laptop i want to repair is a really good one and i realise that if i don’t repair it, it will cost a bobm to get it proffesionally repaired, yed?
I must say though, removing the old jack and cleaning the terminals is a lot more difficult for the unskilled than you make out, especially the positive post (or the one furthest from the edge) there is very little solder to anchor to. If you have no video on both internal and external screens, make sure the memory module is seated correctly.
3 2 of the four holes are blocked and i need to put the new DC power jack onto the motherboard?

If the motherboard receives correct voltage from the power supply, but there are no signs of life, apparently you have a bad board.
Your order will be delivered to the shipping address within 2 to 15 business days after being shipped out .
I use Weller WES51 soldering station and for this job I set temperature to about 800-850°F. 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. Carefully wiggle the power jack without applying any significant force and at the same time heat up all contacts one by one.
If I start up the 1150 with the AC adapter plugged in, I get a message that the AC power adapter cannot be determined and gives me some setup options. This is to prevent you from using a 3rd party power supply, or one that isn’t matched to the current demands of that model notebook. Took it to a repair shop some 100 miles from my home and they told me that I would have to get a new mother board and other thing plus labor cost it would run around $650.00 to repair my computer. Thank you for your contributions to humanity and by undermining those swindlers who charge $280+ for this service. The thing just won’t come out and the solder barely melts only at the exact point of contact.
I am a complete newbie wrt soldering and stuff, but I went ahead and bought all the equpiments suggested here for under 20 pounds, and it took me about six hours to dissemble the laptop again following the tutorial here, fix the soldering and put it back together. That metal thing which I plug into the DC gets extremely hot very quickly in matter of minutes also. So all im stuck on now is how to correctly dissassemble the case and also how to correctly SOLDER! If solder joints have no cracks, the power jack is in a good shape but the laptop is completely dead, most likely it’s bad motherboard.
If you need other more fast delivery modes, such as UPS, USPS, Please email us The shipping fee will be added based on weight and size of the goods. Im a college student living on college budget and couldn’t afford to buy a new laptop and the warranty is already up.
It is my daughter’s laptop, she was pushing the tip around to get some intermittent charging until it would go no more.
I went back home thinking about buying a new one then I used my other computer to see if I could get help on the internet to fix it.
After finding this sight I went to the store to buy me a soldering iron and took apart my computer for the first time. Tried your link but it takes me to a maintenence manual that is about cleaning, travel packing, but no dissasembly instructions. Thanks for the step by step instructions I got my computer going and it feels realy good to know that their are people out there that can hep out and make a difference and save some major dollars.
