Question about Acer Aspire 5920-6727 Notebook
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
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,
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.
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)

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.

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 ?
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
