It's a little more involved than just removing the keyboard. You have to
Completely disassemble the laptop, until just the motherboard is in your
hand.

HOWEVER, for this Acer model it's a different installation, than the
normal one. This DC Power Jack uses a small wire harness. You just
unplug the old one, and install the new one. Let me explain,

I'm a tech who normally works on HP, Compaq, IBM, (Lenova now),
and Acer laptops. Acer's that are older than yours. All the DC Power
Jacks that I have replaced, are directly soldered to the motherboard,
and have no wire harness leading off of them. No plug connector on
the end of a harness, either.

In my search just now for a replacement power jack, my findings show
that the Acer Aspire 5920 series have a small wire harness.
Let me show you,
http://www.notebooksolutions.ca/zc/index.php?main_page=product_info&products_id=2977

Here the jack is offered minus the harness. You have to unsolder your old
harness from the defunct power jack, and solder it to the new one.
http://www.laptopjacks.com/view_part/Acer-Laptop-DC-Power-Jack-AC231916.html

You'll find the body of the DC jack is made of plastic. There is a metal
pin in the center. (This is the Positive post. + )
Some DC power jacks have a metal cylinder, or metal tube shape that surrounds the Positive metal center pin. This is the Negative connection.
Some just have a flat metal contact prong in the back for Negative.

If you have your AC adapter plugged in, and the plug is bumped, the metal
center pin can break loose from it's mount. Break loose from the plastic
body. Same thing for the metal 'shell' for the Negative connection, but this
doesn't happen as often.
Again, most DC Power Jacks have metal flat prongs that come out of the
power jack's body, go through the motherboard, and are soldered on the
backside. These solder connections can crack, and break, making an
intermittent connection. Doesn't seem to be the case for yours, IF the
jacks shown are the correct ones.

This may help you in your endeavor to disassemble your Acer Aspire.
(AND reassemble!) (TIP from me. DEFINITELY buy an ESD wrist strap
and connect the alligator clip to a good ground. They only cost about
$5 to $7 dollars. They are to relieve static from your body. Electro Static
Discharge wrist strap)

    I have an Acer Aspire 6930 that I cannot plug the DC power plug all the way into the jack. I have to hang it at the very end of the plug. When I do this, everything works fine. I tried a new power supply and that didn't work. So, I changed the DC power jack. The same problem still exists with all new stuff. Why?

You have a loose connection of your power jack in your computer. Do not force to wiggle it else, it will create more damages to your computer. Have an expert to open the back channel/portion where the jack is located or some screws to open the back portion of the computer. Have a fine point soldering rod and soldering iron but be sure if you do this, you have to clear surroundings of possible short circuits after melting the loose jack connection.
This procedure comes after you check all external connections of the battery from the AC/250v or in other countries 110v to the wires and the power supply. If it's all ok, then proceed with the fixing of loose connections inside your PC or the power jack. Don't try to guess that the power jack is the cause. You might find out after all that the problem is not in the unit but the external power supply.

Thanks.

Toshiba satellite a355d-s6921 dc jack replacementHi all,
I'm having a bit of trouble. I completely took apart my laptop to replace the dc jack. However, when it cam time to disconnect it from the mobo, I accidentally snapped to of the prongs. I have know idea how to remove them. It seems the other side may have been soldered on. I tried using my sodering iron (30watts), but it doesn't appear to have any effect. It's so frustrating because this is literally the last step,and inserting the replacement looks terribly easy. Does anyone have experience removing the jack from this board.Or know how powerful of asoldering iron I should use to remove the prongs.
Thank you so much for your time.

Is the plug and cord at fault ?
or
the socket itself on the machines body?

Best thing to do is to take this unit to a service agent for the repair,
I could tell you how to remove the keyboard but if your not familar with this type of repair then the dc power is going to be the least of your problems ,Static kills computer chips DEAD and Quickly
if anything goes wrong,
least its with the correct people for the repairs,
They can endorse a warrantee too.....

Anyways,the component is normally mounted on the motherboard,
But the sockets arent on the shelf at your average electrical wholesaler either,normally only avaialbe thru agents too,booo....
you could probably order them if you had the correct part numbers and minimum quantities ,,,,,,

Take it to an agent or replace it ,simple really

Hope this helps ,Misterdj

You need to get the DC Power Jack Either Repaired or replaced...this is the "female" port where your AC Power cord plugs into.. To Repair the current DC Jack...First you'll need to look closely at the Positive posts to see that they are not broken.. If visibally ok.. then you can look at the Solder Connections.. they will need to first be Desoldered.. Cleaned, then Resoldered back in place.

When i charge my acer aspire the power button flashes


The DC jack in the laptop is showing early signs of intermittent issues, the jack is solded to the motherboard which sometimes breaks free over time, this is something that will eventually need to be addressed.

If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.

The laptop needs the motherboard removed to get access to the DC jack so it can be resoldered or replaced if it is faulty.
This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

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.

(Click on the blue - One - in Aspire One.
This is a PDF file. The computer you are using now has Adobe Reader on it which uses PDF files.
After you click on the file name (One) it may take up to 30 seconds before you see the first page.
It may also take additional time for the file to fully download.

(Took 12 seconds just now for full download)

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)

No power at all, tried a new charger still no power and replaced the battery.


Hi

After the battery and AC cord replacement and still not getting power there's only once culprit there and that is the motherboard of the laptop. I recommend you call Acer and have them replace it for you. Thanks

Is there any way to charge an ACER computer battery other than through the computer. The computer has a burned out recharging jack. Can you recharge it through a USB port.


No, not through a USB port.

Can you find a similar ACER computer for "cheap" on eBay?
It would not need to run -- it just has to accept the identical battery,
and connect to an AC adapter, and to charge the battery,
even when the laptop is powered-off.

Laptop will not charge but charger light is on


Sounds like a bad battery or the charger isn't putting out enough power even though the light is on.But most likely its the battery.
