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! :)

My dv2175ea power inlet faulty


Most power cord ports are soldered directly to the mother board. Open this one up and see if it is a separate part or not. If it is, you could probably just replace the small part, but my bet is that it would take an entire system board replacement.

Acer 6530 has problem with power connector on the laptop, the cord and power supply work fine. the connector is loose and is not working, how do i replce it?


It's called a the DC Jack, and you would have to take the laptop completely apart so you can get to the motherboard then De solder the old jack from the motherboard then solder the new jack on the motherboard. Finally you will have to re-assemble the laptop. If you are not comfortable doing this than I suggest you take it to a local repair shop for repairs.

The power plug is loose and i cant get a good connection


You need to replace the dc jack. This could be a solder on the board type or plugged into the motherboard. Either way, the part cost is only about £4.00, as long as you are capable of dismantling and soldering it is a cheap enough repair

Ac/dc power plug replacement for a dell XPS m1530 laptop


It would be stated as DC Power Jack.

For the Dell XPS M1530 it has a circuit board that is removed.

The circuit board also has the I/O USB ports on it.
(Input/Output)


DC Power Jack I/O USB Circuit Board example,

http://www.parts-people.com/index.php?action=item&id=5400

A lot more convenient for replacing the DC Power Jack.

Examples of a Dell XPS M1530 DC Power Jack,

Round and Octagon.


Dell XPS M1530 Service Manual. (From Dell Support)

http://support.dell.com/support/edocs/systems/xpsM1530/en/SM/index.htm

1) Remove ALL electrical sources. AC adapter (Charger) and Battery.

2) Use an ESD wrist strap, and connect the alligator clip to a good ground source.
(Cost averages from $3 to $12. I connect to the metal frame of an empty desktop computer case)

3) Use a multi-compartment container for the various screws you will remove. Label each compartment for the area the screw/s came out of.
(You can use a clean egg carton in a pinch. Label each each holder)

There may be as many as 60 screws, and 12 different types of screws.
DO NOT mix them up.

4) Make notes and drawings as you disassemble. Use a video cam if available. (Use good lighting)
Nice to have a record to come back to if you are interrupted.

5) I suggest using Solder Wick, (Desoldering Braid), for desoldering.

A lot better IMHO than using a Desoldering Tool.
(Solder S u c k e r tool)

50 Watt of less soldering iron, No.2 chisel tip.
.055 Rosin core solder
Rosin paste flux
Solder Iron stand with a damp sponge, or a damp sponge nearby.

Bad AC adapter port


Hi,

The majority of HP laptops I've worked with have had the DC socket "on-board".

But, don't worry about having to replace the whole motherboard as you can now purchase an new DC socket for the laptop and solder it in yourself. Or you can just take the laptop to a reputable PC repair store and have them fit you a new DC socket.

This is a very common problem with all makes and models of laptops (except Apple Mac's) and i have replaced plenty of them.

Please post back if you need anymore help.


Regards.

Dell Inspiron B130 - can you replace the connection for the power source/battery charger? Mine is shorting out and not always charging the battery (new battery, new AC cord and adaptor).


Yes you can replace the power adaptor. You may also remove the solder from the existing adapter and re-solder it back on which is what I did. If you just want to replace it I suggest Ebay before I repaired mine I ordered a new one for $5 w/ free shipping.

Will not hold charge, touch power cord on back or move it any way and the computer shuts off, the third light bar on front of computer keeps flashing between red and green


DC Power Jack is bad, or it's solder connections to the motherboard.

To explain;
The DC Power Jack is the port you plug your AC adapter into. (Charger)

Your DC power jack Not installed looks like this,

http://www.megaemarket.com/dc-power-jack-for-dell-inspiron-laptop-b12120130.html

(You can click on the photo to enlarge)

Looking at the jack in the photo, it is upside down in relation to how it actually sits, on the motherboard.
Those flat pins you see go down through the motherboard, and are soldered.

As I'm sure you know, your laptop uses DC electricity. (Direct Current. A flashlight battery, and your laptop battery are examples of stored DC electricity. The AC adapter converts AC electricity into DC for the laptop)

The round metal pin in the center is for Positive. It is the Positive connection. The outside round hole has the Negative connection. (For this jack I believe it is a flat strip of metal going down the side of the hole)

What you can't see is that the body, or outside shell of this DC Power Jack is composed of Plastic. Looking at the photo, look at the rear view of the jack. The view on the right of the photo.
That metal center pin is riveted to the flat pin. (Or Prong, if you wish)

Doesn't take too much of a bump, when the AC adapter plug is installed into the jack, to break the plastic at this point.

However your jack may not be broken. It could be cracked solder joints. Solder joints where those flat pins are soldered to the motherboard.

I apologize for being so lengthy, but unless you repair these babies, you may never know this information, and I thought I would share.

I wanted you to know what the problem is.
It is my belief without looking at this laptop, and based on many repairs, that your DC Power Jack has cracked solder joints.

Only a professional, competent, tech will know for sure when they go to repair it. If the above is the case they will re-solder the joints.

Repair cost? This cost varies from city to city, and country to country. I could only hazard a guess.

In my area it varies from $50 on up. (The cost of the jack online is about $9 should one be needed)
(The entire laptop needs to be disassembled down to the bare motherboard. {The LCD screen stays intact} Then work on the jack can ensue)

Acer aspire 3680 won't turn on / Black out.


This line of Acer laptop has numerous power issues. If the laptop actually will not power you will likely need to perform some component level repairs. If it powers on but does not complete POST. (Meaning you dont see anything on the screen) Then you would want to begin by removing the center panel on the bottom case. Once removed locate your memory sticks and make sure that they are seated properly. Remove them and reseat them. Try to power the laptop again and see if your problem is solved. It is possible that if this does not work that the memory is actually bad and must be replaced. There are quite a few other things that can cause this. Memory is the easiest to repair. This failure can be caused by a defective CPU as well, but for the average computer user I would not suggest taking your PC completely apart. If you are comfortable doing so you will want to disassemble it, remove the logic board and use a test CPU to see if this solves your problem.

In case your unit actually doesn't power on it changes things. The first thing you need to check is the status of your AC adapter. If you do not have a voltage meter you would need to use a test adapter to elimiate that possibility. More likely the problem is caused by an internally broken DC connector. This happens very frequently and is a rather simple repair if you posses decent soldering skills. You can purchase one of these DC connectors from ebay for $2 or so. Disassemble the laptop, remove the two screws that attatch the DC board tp the main board. Desolder the DC connector and replace it with the new one. Sometimes this DC board will have been damaged from a power surge. In this case the entire power plane connected to the back pin of the DC connector will likely be shorted to ground. If this happens remove the old DC connector, cut off the back pin and solder and heavy gauge wire directly to the back pin. Run this wire around the DC board on the left side of the DC connected as you are looking at the connector fromthe front. On the other side of the DC board you will see 2 farite beads wired in parallel. They connect the shorted power plane to the next. Remove these two farite beads and run the wire to the contacts on the next power plane. This will bypass the damage to the DC board.

If the DC connector is the the cause for the problem. There is a pair of capacitors on the logic board that fail very often. To see them you will need to remove the heatsink assembly from the logic board. They are ceramic capacitors right next to the CPU socket. They are wired in parallel and may bot show any physical signs of damage. If you have a multimeter set it to test continuity and put both leads on eachside of the caps, if you hear a constant beep then the caps register as shorted. Remove them both from the logic board and repeat this process with them outside the circuit. If you touch the leads to each side of the caps and hear nothing, then the cap is good. If you hear the same continuous beep then the cap is shorted and is the cause for your power issues.

If these suggestions have not solved your issue, then the motherboard may still be repairable but will require an experianced technician to isolate the cause for the no power. Good luck.

Warreny over , fix it myself ?


I don't think you'll be completely happy with this, but I'm pretty sure the DC Jack (the power plug you broke) is soldered onto the power control board. This doesn't mean it's not repairable. I've done this with some good success in the past, but you might just want to replace this entire "daughter" board. HERE'S ONE on eBay for about $75, a lot less than the $200 for the mainboard or more for a complete replacement or repair. You could try to repair the DC jack and if that $12 fix fails, replace the entire Power Control Board (PCB). I think you should take it apart and check at least. It isn't that difficult if you have patience and the right tools. You'll need a "computer" or "electronics" screw driver kit and something like a credit card to help pry apart plastic pieces without scratching them. I also found this thread on NotebookReview that talks about doing what you want to. To see what the board looks like check out these pictures: eBay: 3680 mobo1 http://i17.ebayimg.com/04/i/001/0d/e1/7ce9_1.JPG To pick up the DC Jack you'll need, check out eBay, they are around $12 shipped. HERE'S ONE EXAMPLE GOOD LUCK!
