DC Power jack broken

The dc jack on my son's computer is broken. I can't find a replacement jack. Its a lenovo 3000 v200. Nobody online seems to stock them. Maybe the same jack for another computer would work? Or, any other ideas?

Re: DC Power jack broken

Looks like you're right, I did not see any Lenovo replacement jacks either. You might try looking at the IBM Thinkpad jacks for various models to see if you can find the same jack.

I've repaired 3 laptops with this problem. Rather than replacing the jack on the mainboard I wired a "pigtail" to the mainboard and then zip tied a female connector to the back of the laptop itself. I did this because the mainboards were pretty beat up from the heat the original jack produced as it began to loosen. The end result is not as pretty as the original jack, but it absolutely takes all the stress off the mainboard. Those computers will never have this problem again.

Good luck.

Re: DC Power jack broken

The rear panel houses a power jack (it differs from the standard IBM connector, the new jack is used in all 60-seires Thinkpad models and Lenovo 3000. The power is also different now - 20V 4.5A instead of 16V 4.5A), modem jack and a video out.

Acer Aspire E1-571-6650 would not charge. Problem thought to be DC Jack (AC Adapter would not fix and DC Jack seemed loose). Had the same problem a year ago in July and it was fixed. Original charger...

Difficult to comment but if a laptop comes in for me to repair and the hinge is broken and maybe cabinet damage, I would offer to replace the broken parts and replace the DC jack, if it was faulty. It is part of the service but may not be cheap to repair!
Hinges usually become loose and very rarely break.
Did the laptop work on the power supply but not on battery?

Lenovo thinkpad plugged in not charging is there a problem

laptop plugged in not charging:

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 IBM ThinkPad X40 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.

I need to replace the charging port on my Lenovo 3000 Y410

the power port (dc jack) on a laptop is an easy fix. a repair shop will strip the laptop down to get to the motherboard and solder a new jack onto it. the dc jack should only cost a few pounds (can usually be found on ebay) so the main cost will be for labour. If the charge is over 25 pounds I would shop around because it should take about 30 mins to fix.

Broken dc jack on acer 3003ln

If the internal DC Power Jack is loose, you will have totake the laptop apart to repair it. The DC Power Jack is on themotherboard and most times it is soldered to the motherboard. That meansyou will have to desolder the old one and solder a new one in it's place. Sometimes the dc power jack sits in a slot between the bottom case and palmrestwhich hold it in place and has a cable harness that plugs into the motherboard.

Notebook won't power on

Take the battery off and try to turn it on with just the power cord. If it works then it's your battery. If it doesn't then it's either your ac adapter or your dc jack. Try an ac adapter from a local pc shop or electronics shop. AC adapters run around 40 dollars or less if you order them online. DC jacks are a different story. I the jack needs to be replaced you'll have to take it to a pc shop or if you can do it yourself then order a dc jack online or purchase it online and take the computer apart replace the dc jack (you'll have to desolder the old one and solder the new one one). Good luck!

My laptop lenovo 3000 N100 battery has a problem.. therefore i purchased a new battery but the problem with this battery is that when i use the battery it runs the laptop for 10 -15 mins and then with a...

My Dell laptop has a power problem.
The Dell Precision M20 Battery stops charging when I move the power cord on the DC adapter. When I start moving the cord left to right, the power LED light on the front goes on and off and the battery charge LED goes on and off too.
I removed the precision m20 battery and tested the laptop again. The laptop starts fine from the DC adapter when the battery is removed, but as soon as I start moving the power cord the laptop shuts off. It looks like the laptop looses power immediately.
If you have a problem like that, most likely it’s related either to the power adapter or the DC-IN power jack.
First of all, I tested the laptop power ac adapter with a multimeter. The power didn’t cut off no matter how badly I moved the cord. The power adapter output voltage was 15.45VDC all the time. That means there is nothing wrong with the power adapter and most likely there is a problem with with the power socket inside the laptop.
Now I’m going to test the power socket inside the laptop.
In order to access the power socket I had to disassemble the laptop and remove the top cover assembly with the display.
You can find disassembly instructions for many HP, Dell, IBM, Lenovo, Sony and Toshiba laptops in these service manuals and guides.
In the laptop I was fixing (Tecra M2) the power jack is attached to a DC-IN harness and this harness can be unplugged from the motherboard.
As you see, I removed the DC-IN harness from the motherboard, plugged in the power adapter and tested continuity with my multimeter as it shown on the picture.
When the power cord is still, the voltage output is 15.45VDC, the same as on the plug.
But as soon as I start wiggling the plug inside the jack, the power cuts off and voltage goes to 0. It means, the power harness is bad.
The problem was fixed after I replaced the defective DC-IN harness with a new one.
In some laptops the power socket (DC jack) is soldered to the motherboard.
If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.
You cannot simply unplug the jack and replace it with another one. You’ll have to unsolder the old jack and solder a new one back on the motherboard as I described in this post.
If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.
If you want to buy a new one,you can see more information from

My power jack is broken. Need directions on how

You need to take the unit apart down to the system board. Sorry, I do not have the sefrvice manual.

The link below shows how to resolder the connector on the system board.

Motherboard or harddrive? I'm betting it's more towards the motherboard. The DC Power Jack to be more specific. This is the port where the AC adapter, (Charger), plug is plugged into.

The DC Power Jack is not much bigger, than the plug for the AC adapter that plugs into it. There are small pin leads that are on the bottom of this jack, and they go through the motherboard, and are soldered to the motherboard.

Accidental bumping of the AC adapter plug, while plugged into the DC Power Jack, can damage the jack. It can break the connections for the adapter plug, and/or can crack the solder joints for those small pin leads.

[Laptops use DC electricity. A flashlight battery, and a laptop battery, are examples of stored DC electricity. DC electricity has two poles. Positive and Negative. The DC Power Jack has two connections. Positive and Negative. {Even if the DC Power Jack has multiple holes in it]

There is also another known problem associated with DC Power Jacks. It may stem from a bad motherboard design.

More to the point, the area where the DC Power Jack mounts on the motherboard. In this design, the DC Power Jack motherboard area, is almost a separate part of the motherboard. It's shaped like a Peninsula. (Think of an island, with one side connected to the mainland)

This peninsula shape, has the tendency to crack away from the main body of the motherboard. Circuit traces are broken.

When the AC adapter plug is setting in a certain position, it presses the two broken halves of the circuit traces together, for a momentary contact. As the AC adapter plug is moved from this position, the circuit trace halves are moved apart, and there is no contact.

(No distribution of electricity from one circuit trace half, to the other circuit trace half. Think of a circuit trace as a very, thin, flat copper wire. When a circuit trace is broken, there is essentially a wire that is broken into two parts)

See if the DC Power Jack can be repaired, (Solder joint connections re-soldered), or replaced.
If the DC Power Jack motherboard area is the aforementioned peninsula shape, it may require replacement of the motherboard.

There are very FEW, computer repair shops that have the technical expertise to replace a DC Power Jack. Easy fix is to simply replace the motherboard. (More $$$$$ too)

However, some laptops DO require replacement of the motherboard for this repair.
Bad motherboard design, for the DC Power Jack area on the motherboard.

Re-solder DC Power Jack solder joints? (IF, this is the problem) Average is $50 to $75 (US)
Replace DC Power Jack? Average is $125 to $150. (US)
Replace motherboard? Depends on the Gateway model. Could be $225 to $400 (US)

[Yes, most of the time the cost warrants just replacing the laptop itself, as the cost of replacing, is close to the repair cost)

Just to SHOW you ab average DC Power Jack, and the repair involved of replacing. (Doesn't show you, that the entire laptop needs to be disassembled, down to the bare motherboard in hand)

This is NOT a recommendation to replace the DC Power Jack yourself! It is just for knowledge of what is partially involved. (You can accidentally burn the motherboard when desoldering, or soldering, rendering the motherboard useless)

Power connection broken

Sounds like the DC jack on the motherboard is broken. The jack is very inexpensive, but difficult to replace as it's surface mount soldered to the board and the laptop will have to be disassembled or the plastic case cut/modified to replace the DC jack.

DC input jack broken

Yes it's not usually something that can be repaired at home. Your chances are better if the jack just seems loose and not actually broken, however replacing it is better. I work for a Laptop Repair Shop in NYC and we deal with this issue frequently.
