Have you opened up the laptop? Online it looks like this jack isn't actually attached to the motherboard judging from this posting:

I usually go to Laptop Jacks but couldn't find your model of laptop. Usually you can call them and they will send you out the right jack.

Hello, power failur on mother board p/n cp298380-01


So how is the DC Power Jack solder joints on that Fujitsu Lifebook?

The DC Power Jack (DC IN) is the jack on the laptop where the AC adapter (Charger) plugs into.

Do any of them look oxidized?
Dull finish on any of the solder joints holding the DC Power Jack to the motherboard.

De-solder and makes fresh solder joints.

Are any of the solder joints cracked?
Cracked at the area of the solder joints to the bottom of the motherboard.
Re-solder.

What condition is the DC Power Jack itself?
Physical condition of the jack.
Bad physical condition requires replacing.

Do you see any discoloration, or burn spots on the chips on the motherboard?
(I.C., Integrated Circuit = Chip and Chipset)

There is a sensor chip on the motherboard for power. Senses when the battery needs to be charged, or doesn't, and when the laptop is to just use the AC adapter power.

If so replace the motherboard.

Post any questions about the above in a Comment.

My fujitsu A3130 screen doesnt turn on. the only thing it does is that the 3 lights in the top right corner turn on and off.


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced.

How do I replace fujitsu 2727 power socket


Get it fixed by going to jackfix.com , replacing the dc power jack requires taking apart the entire laptop, then removing the motherboard, and finally desoldering the power socket, and resoldering the new jack, and putting everything back together, its no job for a beginner. Not being rude at all, but if you have to ask how, dont attempt. http://www.jackfix.com , they have replaced many power jacks for my laptops, as well as my companies, they give a lifetime warranty, and will ship the laptop back to you within 24hrs. believe me, I have tried different companies, and they are def best.

Hi

DC jack replacement is easy however requires a bit care since its mounted on the mainboard. Desolder the old DC jack. Solder the new one firmly. Dont keep the soldering iron too long on the PCB as it will damage the lines and will deform the DC Jack. You can get DC jack very low cos from local repair stores or you can order from Toshiba parts depot (800-524-8338)
Please post your question if you need further assistance.
Good Luck

Fujitsu S6120 laptop power problem


I fixed my S6210 wen the poorly designed connector broke. Fujitsu wanted $ 250 to do the job. The part is only $ 5. I also bought a Cable Retention Device to keep from jerking on the cable.

Here's a video that talks about the problem and the cure.. . .
