I need to replace the DC jack on my laptop

How do I replace the DC jack

Posted by on

  • wccx4jg24 Nov 27, 2008

    I am pretty confident I can do the repair properly, but I cannot get to the motherboard itself to have a clear area to work on the jack of my Dell inspiron 600m. The chip cooler seems to be attached by posts, and an internal plastic skeleton is blocking the terminals where I would need to get in to desolder it. Any ideas?

Do Not Attemp to Replace the Jack Unless You Have Experience with Soldering... The Original DC Jack Must First Be Desoldered and Removed... You Need A Desoldering Pump or Solder Wick (braid) To Remove the Old Solder From The Jack Post Pins..... DO NOT ATTEMP TO RIP OUT THE OLD JACK!!!!! You Will Pull The Contact rings from the center of the motherboard out and render the motherboard useless...


Slowly and carefully Unsolder the dc jack, Remove it and Clean the board.... Very Important to Clean the Motherboard after desoldering the old jack.... You Must Remove all old Flux...

Then Apply a light layer of fresh solder to all the contacts on the motherboard....

Apply Flux paste to the New DC Jack Pins and a light amount onto the contacts on the motherboard....

Insert the new DC JAck Into The Slots and Apply Solder to all points on the underside of the motherboard....

Flip The Motherboard Back Over, To THe Side Where THe DC Jack Is,, and Apply Flux then a light amount of Solder To The Side Pins and Back Power Pins ...


Then Clean the Motherboard off again using an Electronics grade circuit board cleaner (found at radio shack) or a tiny amount of denatured alcohol applied to a paper towel .. THe Purpose is to remove any remaining Flux..... as this will just deteriorate the New Solder over time unless cleaned off...

Good Luck

While I am not familiar with this particular model, most Toshiba laptops I have encountered have the DC jack soldered to the motherboard. If it has become disconnected, then reconnecting it is quite possible, but does require some skill. If you do not already have experience with soldering and/or PC repair, I would suggest asking a friend or family member who does.

In addition, if the laptop is still under warranty, I would speak to Toshiba support, as this problem is sometimes covered. Just back up your data first!

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 ]

A few articles dealing with replacement of a DC Power Jack,

http://www.laptoprepair101.com/laptop/2006/05/27/failed-laptop-power-jack-workaround/

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 connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.

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.

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

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

DC Power jack heats up to very hot to touch on HP NX9010 laptop.


The DC jack, where you plug the power adapter cable, might be loose or defective, & needs to be either re-soldered or replaced.
In order to do this, the laptop needs to be disassembled & the motherboard taken out. Also, the motherboard needs to be checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

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.

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)

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.
