Hi There,

I deal with this problem often for my local clients. I used to disasseble and repair or replace the Dc Power Jacks but you have to remove the motherboard and know your soldering well to do so. Nowadays, I just send all laptops with this problem in to any one of several different repair vendors on eBay.

Go to eBay and in the search box type, Laptop DC Power Jack Repair. You'll find a host of reliable companies there and with the repair and shipping you should expect to pay around 80 to 100 dollars. If you can find someone locally you trust to do the replacement for less then take that route.

Best Regards

Apparently the DC connector broke. If the warranty is still in operation, have it repaired; else, the damage can be easily fixed by any electronics shop, or even by yourself if you're familiar with a soldering iron for electronics. This guide is for a different model, but the DC section is practically the same in all laptops:

I have an ASUS eee netbook. Recently the power cord hasn't been connecting well to the computer and now it doesn't even register. It's plugged in but isn't charging. Is it the cord or the laptop?

  3. The battery will not get charged.

My elitegroup laptop was no power at all, then the pin positive is shorted to pin negative


DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Power socket is loose


dc jack socket for Sony VAIO VGN-FW is very easy to loose, I think you can replace the cabled dc jack, no solder work, plug in and work, see this reference page: http://www.lapdiy.com/sony-vaio-vgnfw-series-power-jack-port-connector-dc-in-cable-p-2647.html
the above item is with ground cable, it is known that sony FW uses both harnesses with or without ground cable, you can cut the ground cable directly if your laptop does not use it, or order from this page for the one without ground cable: http://www.lapdiy.com/sony-vaio-07300012492a-power-jack-port-connector-dc-in-cable-p-2782.html
hope this can help you

Dell Inspiron 1505; Battery does not charge; DC jack is loose..


You have either a faulty connector plug on the power adapter which connects into the laptop or the loose power input socket on the laptop is faulty. This is because you need to press the connector upwards to make electrical contact.
Test the connectot plug on the power adapter with a multi-meter, wriggle the connector to see if your get the voltage to fluctuate, if it does not then the connector is OK anf the fault is in the laptop power input socket.
If the fault is in the power adapter plug or the laptop's power input socket, this can be repaired, a techo would have no trouble in repairing these faults.
