SOURCE: Acer Aspire 4520, power jack
You may be able to buy the whole assembly on Ebay. I bought one for my averatec laptop and it just popped into place, no soldering. It was about $20

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)

If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot fix this yourself then I suggest you get a quote first.
