No power going into power jack

Any sugestions on how to take the laptop appart to resolder the power pin?

You would be better off phoning small pc repair stores and getting the best price to replace it
not a good idea to fix it yourself
the cost usually runs between $60.00 - $100.00
I know people that fixed me themselves and believe me they have ended up with problems

Acer Extensa 5620: The power supply jack is loose when you plug it into the laptop. Sometimes it will provide power and sometimes it will not (orange battery light on front of laptop goes on & off)....


System check
1. estimate the extent of damage, possibly requires entire board replacement housing the extension power supply modulators, possibly due to physical damage on contact.
2. Aslo check the battery life since could determine the possibilty of substituting power chord from currrent outlets with batteries

The device would not connect to power outlet without a properly functioning battery installed. A depleted battery could not be replaceble by connecting a source out power outlet. each parts of the power complement the entire process of achieving computer experiece.

Consult a technician insisting the replace the entire power system of battery and ac adapters and also fixing damages on the mother board may be contributing to power leakage

Acer travelmate 5520 will not switch on when powered by battery or ac


1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

The dc power jack will not accept power. I have to wiggleit to get the blue light to show that the laptop is charging. My computer is the acer aspire 5920-6423. I dont know how to remove the key board to...


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)

Can't get to the mother board on Acer Travelmate 4011


All i can really offer for help is to try to remove the screws on the underside of the notebook. That is how i have to remove the keyboard on my Sony vaio. I cannot find anything online that describes how to remove the keyboard. But i can say when you get the keyboard off follow the link i provided above and click on the link that says "How to fortify damaged power jack connection in a laptop" This gives excellent instructions on how to repair this jack.

Or if you want to buy a new one follow this link to buy one off e-bay.

If you look on the laptop repair link it gives you a good idea about how to remove the keyboard so follow those directions as close as you can. And remember that these computers use a lot of snap fasteners so some stuff may be snapped in place and not screwed down.

Acer power cord connection


Don't pull your hair out,.. it's not an uncommon issue.
You don't have to replace your board. At least one of them sounds like the connector has come loose
or has issues, and needs replaced. The other sounds like the adapter itself. I ordered a new adapter on
Ebay this morning for about $28 total for a Compaq Presario and all laptop models seem to be about
the same price for adapters on that site. As far as replacing the connector,.. you in luck, there are
several places on ebay that you can send the laptop to ad they will diagnose the laptop and if it
is the connector they have a 1 day turnaround. Think that service is about $100 or so possibly
cheaper. On EBay search for 'laptop power jack repair'.

If you don't feel the value of your laptop is enough to warrant such an expense you can order a
replacement jack instead and try and tackle replacing it yourself. ( there are listings to order
just the power jack )
