Yes.
Is the connector on the power adapter that plugs into the laptop?
If so, this is an easy repair, purchase a new connector from electronics parts shop, cut off the old connector and solder the new one on the end of the cable. MAKE SURE YOU SOLDER THE CONNECTIONS TO GIVE THE CORRECT POLARITY ON THE CONNECTOR, OR YOU WILL DAMAGE THE LAPTOP.

If the power socket on the laptop is faulty, this repair is more difficult. The socket may only need resoldering on the motherboard or in the worst case a new socket replacement. Either way the laptop need to be dismantled to get at the power socket.

If you don't feel you can handle this, get it done by a computer repair shop or a techo friend.

SOURCE: 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.

SOURCE: how to replace dc power jack for toshiba p15

Take apart laptop and see what type of jack is on your system. There are two types. one is soldered on and the other is a module that connects to the motherboard with a wire connector.

If you have a soldered on type the you will need to de-solder it from the board then solder a new one onto the board. most ac jack issue just need to resolder it unless the jack itself is broken.

Power supply blown


You can check your AC adapter by voltmetter in Dc mode, one probe touches inside the plug, other probe touches outside, it should have dc reading if the ac adapter is working.
Your plug is slightly burnt, indicating that the DC jack is broken or loose.
Most DC jack can be replaced if you know how to solder, it costs only under $5.

http://cgi.ebay.com/DC-Power-Jack-Fu...3286.m20.l1116

I believe your DC jack needed to replace and a repair guy might charge you over $150 to replace a $3 part. You should do it yourself if you have a skill to take a laptop apart.

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.

Presario laptop issue with power indicator light and detecting powers supply


Sounds like your DC Power Jack is bad or broken. The DC Power Jack is where the power cord plugs into the laptop? Most times it get damaged by too much stress on it such as sitting in bed with the laptop, or putting the laptop in the laptop bag with the power cord still plugged in.

Take an ink pen and put it into where the Power Cord normally plugs into the laptop. If the pin inside the DC Jack is loose or wiggles then the jack is probably bad. Sometimes the jack can be completely burned out and you can smell smoke .

Broken power plugin port


The power plug in port you refer to is the DC Power Jack.

The AC adapter (Charger) converts AC electricity into DC electricity.
DC electricity has two poles. Positive, and Negative.
(Just like on a D cell flashlight battery)

The center pin of the DC Power Jack is the Positive connection.
The outer metal spring-like pieces, on the inside of the cylindrical shape surrounding the center pin, are the Negative connection.
(The pieces of spring-like metal, all connect to the Negative connection in the DC Power Jack)

Example of a replacement DC Power Jack, for the Asus Eee PC 1005HA Netbook,

[ Note*
Cannot agree with the replacement instructions they offer, at the bottom of the page.
Not everyone has access to a hot-air gun. A 25 Watt soldering iron, and Desoldering Braid, is better, and more easily accessed ]

1) Remove ALL power. Remove the AC adapter, (Charger), and Battery.
2) Observe Anti-Static Precautions. Buy, and use an ESD wrist strap.
Electro Static Discharge.

(Average cost is from $3 to $6. Connect the alligator clip to a good ground source.

I have an Acer Aspire One and when I plug the charger in I have to spin it or wiggle it or both to get the battery to charge. Once I have it in position it generally stays on charge, but if the cable is...


It could be either one Sarah.

The AC adapter's (Charger) cable, or the DC Power Jack where the AC adapter plugs into the laptop.

This is an example of the DC Power Jack not installed,

http://www.laptopjacks.com/view_part/Acer-Aspire-ONE-AOA150-ZG5-DC-Power-Jack-AC351816.html

(You can click on the three views of the jack to enlarge)

1) Check the DC Power Jack to see if it's in good repair.

Battery removed use a small flat tipped screwdriver, and Gently see if you can move the Center Pin around in the jack.
See if the Center Pin will move side to side a small amount. There is supposed to be No perceptible movement.

Referring back to the closeup photos of the DC Power Jack, the flat blade-like prongs are upside down, in relation to how the jack sits on the motherboard.

The flat prongs go down through the motherboard, and are soldered to the motherboard.
If the center pin of the jack is stationary, but the jack as a unit moves around, one or more solder joints, (Connections) for the flat prongs may be cracked.

The repair consists of completely disassembling the laptop, removing the broken DC Power Jack, and installing a new one.

No perceptible movement of the DC Power Jack? Suspect the cable of the AC adapter right near it's plug. (Plug that plugs into the DC Power Jack)

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

Hello my laptop t41 power is not even flash but the adapter is working,am technician and i have troubleshoot allot.


I concur with what Diegotech stated.

To iterate further;

1) The DC Power Jack (DC IN), may have cracked solder joint/s on the motherboard connector, (Female), where the DC Power Jack plugs in.

Resolder

2) The DC Power Jack may be broken.
Center Pin mount, and/or body of DC Power Jack, and/or Outer Shell mount.

Replace DC Power Jack.

3) Wires from the DC Power jack plug to the female connector on the motherboard, may be bad.

Replace DC Power Jack.

Two examples, of a place to buy an IBM ThinkPad T41 DC Power Jack,

2) http://www.machinaelectronics.com/store/buypart/IBM_Thinkpad_T41/DC-P001

Past this point it's a bad DC sensor on the motherboard.

Replace motherboard.

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.


It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

MY GATEWAY LAPTOP NO LONGER RECEIVES POWER.


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)

Solution?
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)
