Acer aspire one charging port loose


If I recall this model line uses a fixed DC power jack directly soldered to the main board. When they become loose, you can visually inspect the jack itself (without the cord plugged in), and use a pen or probe to see of the center peg is excessively loose. The common result is the solder connections have been broken between the DC jack and the main board. Often the jack itself needs to be replaced (involving complete disassemble, de-soldering old jack, cleaning, repair PCB if needed, and re-solder new jack in place.
TIP - if it is not charging, remove battery, and gently put pressure from different angles with the power cord plugged in, and try to turn it on. If it turns on with pressure from a specific angle, it would indicate the DC jack is indeed loose, and likely needs to be replaced. It works becomes the pressure is making the electrical contact that has other wise been broken. ALSO, if it turns on easily, yet losses power at certain angles, its a similar issue.
TIP2 - If it still indeed charges regardless of the angle, and does not lose power, it may be a "Modular" DC jack, meaning the jack connects to the main board through a wire harness, and is less prone to breaking the electrical contacts, and the jack is simply loose inside it's retaining clips/slides. Minor disassembly and hot glue are quick fixes for this since usually the plastic clip/slide in the chassis have broke.

GOOD LUCK! :)

The DC Jack is the socket into which the power cable plugs into your notebook. If it has come loose the the solder points connecting the jack to the motherboard have broken contact and that is why the notebook is not charging. A loose DC jack is not suitable for DIY repair unless you are experienced in internal notebook repairs and have all the right equipment.
The only way to get this fault repaired is for a professional notebook repair technician to completely disassemble the notebook and then either re-solder the original jack back into place or install and solder in a new replacement jack before reassembling the notebook. Because of the skill and time it takes to disassemble repair and reassemble a notebook, repairing a loose DC jack can be expensive, but if you look around you should be able to find an experienced notebook repair center that will do it for $50-$75 and give you a warranty as well.
A DC jack often become loose if it is allowed to directly bear the deadweight of the heavy AC/DC Adapter on the power cable or the cable catches on something wile connected to the notebook. the AC/DC Adapter should lie full weight on the floor during charging. If the cable is not long enough for the heavy AC/DC Adapter to reach the floor, then it should be lifted it up and placed on the desk or table beside the notebook. Any cable length problems should be solved by using a surge-protected power extension cable. Also, a notebook should never be carried around when its power cable is attached to it.

My DC jack broke what should i do.


I am assuming you mean the DC jack on the motherboard in your laptop?
You can repair it yourself, or take it to a repair shop and pay to have someone do it.
To repair it yourself, you'll need:
1) A new DC jack (though sometimes you can fix the broken one)
2) The disassembly guide to your specific model of laptop. Google the phrase "laptop make/model disassembly" and one should come up pretty quickly. Guides are generally step-by-step with pictures included, and putting it back together is just the reverse of disassembly.
3) A soldering iron and solder. 15-30 watts for delicated boards like a motherboard. Once you've pulled your motherboard out, You can de-solder the broken DC jack from the motherboard (if necessary) and solder the new one on. DC jacks are generally 2-4 solder points and fairly simple to press back on.

Dc input jack damage can this be repaired or is it part of motherboard


Hi,

The DC jack plug is soldered onto the motherboard and will need to be de-soldered before a new adapter is soldered into place.
Most reputabele PC repair stores should be able to do this for you but it will cost labour charges as the laptop will have to be completely disassembled.



Regards.

Laptop won't power on with ac adapter or battery


Could be a combination of things.

1) Battery is low. Not enough power to turn the laptop on.
Caused by;

2) AC adapter has a plug on the end of the cable. The plug plugs into a DC Power Jack on the laptop.

The DC Power Jack is bad.

2a) The DC Power Jack has a bad connection to the motherboard, (Cracked solder joints), and/or the jack itself is bad.

2b) Center Pin is loose in the jack's mount.
The back of the Center Pin where it mounts has become loose.

2c) The plastic body of the jack, which composes the jack's case, is cracked. This allows movement of the Center Pin.

2b, and 2c cause a bad connection with the AC adapter plug.

No charge to the Battery, no power to the laptop.

http://www.laptopjacks.com/view_part/For-Gateway-MX6920-DC-Power-Jack-GW51425.html

[ If this is the case the DC Power Jack needs to be resoldered to the motherboard. The cracked solder joints need to be re-melted, (Reflowed)
Entire laptop needs to be disassembled down to the bare motherboard in your hand.
(No Processor, Ram Memory, or any adapter cards mounted to the motherboard. Nada)

OR,
The DC Power jack needs to be replaced.
This entails disassembling the entire laptop, down to just the motherboard in your hand. (Same as above)

The old DC Power Jack is de-soldered, and a new one soldered in place.

Very FEW computer repair shops have the necessary skill level.
They just want to replace the entire motherboard.
IF one is available.
More Ka-Ching for them also. ]

3) The AC adapter is bad.
Not providing power to the laptop, to charge the Battery, nor give power to the laptop without the Battery.

AC adapter cord from adapter to plug, which plugs into the laptop, (DC Power Jack), may have a break in it.

May be an intermittent contact provided by wiggling the cord.
If this is the case the wires have stretched, and broken.
Wiggling causes the wires to briefly touch, and make contact.

Where this cord meets the plug itself. A lot of times there is a break in the wires in this area.

Solution is to replace the AC adapter. There are universal AC adapters you can buy, or perhaps Gateway still has some for sale.

How can I change or repair the DC Jack on an IBM ThinkPad T42?


You have to completely disassemble the whole laptop in order to get to the motherboard & actually remove the original soldering to remove the DC power jack from the motherboard. One thing you need is the right tools (Screwdriver) and the soldering gun.

Google & research a guide for disassembling your IBM Thinkpad T42

Unfortunately there are many sellers of DC jacks for your model and several others. Some of these people sell sub-standard DC jack replacements which are not designed for your laptop, but will fit in the same hole. If the mount points for your DC jack didn't fit the same pattern as your original one then it simply is not the right jack for your laptop. You can suffer issues such as improper grounding, voltage applied to ground and vice versa with some severe consequences. This can damage not only your charging circuit, but may well cause your battery to overheat and rupture. Remember, that not all DC jacks are designed the same way, In fact most manufacturers design their jacks as different from the competition as possible, whether this is their intent or not is irrelevant. Your Dc Jack, however suffers from the dreaded floating pin problem. The main bullet type pin you see at the middle of your jack tends to separate and spin freely, and can be repaired by simply soldering the pin mount on the back. Try repairing the pin on your original jack and reinstalling until a new jack can be found and I'd be willing to bet your problem goes away.

Can the dc power plug be repaired?


If you are referring to the DC Jack..(the port where your AC Adapter Plugs into) then typically No, THey are cheap enough that it is best to replace with new.... Yes they can be repaired, but chances are they won't hold up to the stress, and will just cause problems down the road...

Desolder The Faulty DC Jack... Go Slow, Use Solder Wick/Desoldering Braid... And A Solder Gun...Flip Motherboard to the underside of the DC Jack, You want to put a very small amount of FRESH solder on all Pin ends of the DC Jack - this will allow better flow of the solder when trying to remove...
Then Use The Desoldering Braid and slowly remove the solder from the DC Jack Pin Contact Areas... Do Not Rush or you will ruin the contact pads on the motherboard, you must make sure all solder is removed,,, if you attempt to rip out the jack cause you think its "good enough" you will end up pulling the C ring from the center of the Jack Pin Hole...

Once You Have All Solder Removed Use Some Flux Paste And Again go over each pin to ensure all solder is gone, then you can remove the faulty DC Jack...

Now.. Clean the motherboard where the DC Jack Was... Remove All Old Flux and take your solder gun and go over the Jacks contact pads so that you have fresh solder on all...

Now Add a small amount of flux to all the DC Jack Contact Pads and add alittle to the Pins on the replacement DC Jack.....

Then Solder The New DC Jack Into Place... Solder The BottomSide First... The Pin Ends ..

Then Flip Over and add small amount to the side negative pins and the power pin(s)...

Now you are done..

You can add Some Heat Resistant Automotive Epoxy ( Safe On Electronics) to the sides and back of the new dc jack.... this will double the strength and prevent future damage/wear and tear...

Two things... put your hand on the bottom of it.... is it really hot and second any chance of trying another power cord on that ?. I believe you mentioned you tried that cord on another computer. perhaps use the other cord on yours to test it .
