AC Jack repair

Need guidance to remove cover and get at AC Jack. I believe it has broken loose from motherboard. Repair shops want 100-300 + parts to fix. I'd like to try this on my own. Any help, warnings etc will be greatly appreciated.

This is an easy fix if you are comfortable taking apart your notebook and are able to solder the jack back into place. This is very common problem for HP notebooks. Go to the HP website, find your notebook (I would have, but you didn't list the model) and download the Maintenance and Service Guide. Print it! Don't leave it on your notebook because it won't help you! It will walk you through the entire disassembly process, just follow the instructions. Be careful to keep track of all of the screws as there are a TON that go into a notebook. Once you are down to the jack, solder it back into place. If you find that you need a new jack, you can get them for about $5.00 on eBay.

I own 2 HP notebooks and a friend has 2. We have done this on all 4, with no problems. Good luck

If I need to repair or replace my gateway mx6448 motherboard, which is most cost-efficient: to repair or replace? How would I know the difference? I am not an expert, but can I do this repair or...


Depends on what is wrong. Is it the DC Power Jack? The jack you plug the AC adapter (Charger) into?
Average cost is around $100 for a DC Power Jack replacement. (It's labor intensive, but the jack itself usually runs around $8 to $14 )

Most computer 'repair' shops do not have the skills required to perform this procedure.
The easy way is to just replace the motherboard. (Also more Ka-ching in the pocket)

Just a typical DC Power Jack replacement,

Disassembling a Gateway MX 6000 series laptop,

http://www.insidemylaptop.com/disassemble-gateway-mx-model-ma2a-series-laptop/


Some designs of the motherboard, have the DC Power Jack mounted in an area on the motherboard, that DC Power Jack failure is a reoccurring failure.
The motherboard cracks in the area the DC Power Jack is mounted. (Breaking the circuit traces)
In this instance it's better to replace the motherboard. Of course it's going to fail later on.

Your question: "Can you replace the motherboard?"
I have confidence in you, I believe you can.
Doesn't take a rocket scientist, but does require patience.

1) Remove ALL Power to the laptop. AC adapter (Charger), and Battery.

2) It would behoove you to buy, and wear an ESD wrist strap. (Electro Static Discharge)
Connect the alligator clip to a good ground source.
I connect to the metal frame of an empty desktop computer case.
(Average cost is around $3 to $8. Look online for reference. Visit computer repair shops, and stores like Radio Shack for purchase)

Your body carries Static electricity. Static will fry out (Short Circuit) the hardware components inside a computer. Especially a Processor.
With wearing an ESD wrist strap, and connecting to a good ground source, your laptop is safe.

3) There may be as many as 60+ screws. There may be 12, or more different types of screws. DO NOT mix them up! Use a multi-compartment container, and label the compartments for the area the screws came out of.
You can use a clean egg container, (Or two) in a pinch. label each egg holder.

4) You may want to take photos, and make notes as you disassemble. Makes a real handy guide for reassembling. Also nice to have if you get interrupted in the middle.

Obtaining a motherboard:
You might check Ebay. Sounds like advertising, but it isn't. Just one of my sources.
Also check Laptops for Parts on Ebay.
Some sell a laptop that has a broken LCD screen as the only fault.

My LG R400 laptop has a bad charging port.how do i repair it


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.

Hi

It sounds like one of 2 things

1) The DC jack on your motherboard is loose (You can test by getting some long nose pliers and wiggling the DC jack at the back of your PC if it feels loose this jack will need to be replaced by a reputable PC repair shop

2) The motherboard/CPU itself have blown, again this will need to be booked into a reputable PC shop for replacement

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)

Pin from motherboard is broken. No more power


You'll need to replace the power jack.

Most shops / techs charge $75-100 but that depends on your location.

If you do itself it's about $10 for the jack.

You can get them on eBay fairly easy.

This type of repair is not covered under warranty.

Best of luck!

There are several companies online, or you can find someone in your area, the "AC Power Jack" that you plug into, is soldered onto the Motherboard using 2-4 "Prongs", one or more of yours has "Broken", and isn't making a connection, while the Price of the part is cheap, the repair is "Difficult" if you are trained to do the repair, but I have done 6 or 7 myself, so it is possible, But damage to the Motherboard can occur when soldering the new jack in,"Burning" a contact or something, best to take it to a repair shop,$150-$175, or $5-15 if you can do it yourself, Again "DIFFICULT", so the repair shop is your best bet, the online companies have Guaranties against damage. Google "Laptop DC jack repair"
http://www.DCJackRepair.NET is in the sponsered results. There are self help pages for the repair,

When i plug in a/c power adapter to my toshiba laptop it sparks


Sounds like your ac port is broken. If you can not run it off ac or battery this would be why. There is no current flowing to the motherboard. Is the ACjack loose?. If so you need your ac jack repair. A local repair shop can do this. Unless the system is still in warranty. You should be able to call support and tell them that your notebook is not working due to a malfunction ac port.

I hope this helps you.

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.
