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

There is a bad connection between the power cord and the port into which it fits. this bad connect has lasted for weeks. i've been able to jiggle the cord and situate it so their is a connection. but, now...


The port on the laptop where the AC adapter, (Charger to some), plugs into is the DC Power Jack.
(Or DC-in )

This is an example of an aftermarket manufacturers offering for a DC Power jack, that fits an Acer Aspire 4520 Series Notebook, (Laptop),

http://www.laptopjacks.com/view_part/Acer-Laptop-DC-Power-Jack-AC91316.html

Click on the photo of the jack, showing three views of it. This will enlarge for better detail.

As you probably know computers use DC voltage.
Your laptop battery, and a flashlight battery are examples of stored DC electricity.

Looking at all three views, the middle pin of the jack is for the Positive connection. Down inside the round opening on the side, is a strip of metal. One on each side. These are for the Negative connection.

Looking at the jack in all three views, you will note a flat pin, or Prong, that comes up in the middle, and at the back of the jack.
You will note that it is riveted to the center pin, or Positive connection.

The two flat pins, (Or Prongs), immediately on either side of the middle flat pin, are for the Negative connection. They connect to the strips of metal inside the round jack opening.

In relation to how the jack sits inside the laptop, the jack is upside down. The flat pins go down through the motherboard, and are soldered to the motherboard on the other side.

1.The body of the DC Power Jack is made of a type of Phenolic plastic. Hard, and has great insulating qualities.

It is also easily broken.
If you can move the center pin around, this is what has happened. (Battery REMOVED!)

Solution is to replace the DC Power Jack.

2.Where the flat pins go through the motherboard, and are soldered, is called a Solder Joint. The area where the flat pin meets the motherboard, and solder is applied.

One, or more solder joints can crack.
This gives you an intermittent connection, such as you have described.

Solution is to re-solder the solder joint/s.

3.There are also laptops that have a bad motherboard design.
The DC Power Jack is placed on an area of the motherboard, that is weak.

If you think of a 1 foot square sheet of plastic, as being the main body of the motherboard, and attach a 2 inch strip to the main body, this is the area shape that I'm referring to.

The 2 inch strip can crack, where it meets the main body.
Motherboards have Circuit Traces. Think of them as Very, Flat, Thin, copper wires.
Circuit traces go across the main body of the motherboard, and lead to the 2 inch strip. If this 2 inch strip cracks away from the main body of the motherboard, the circuit traces break.

If you move the AC adapter plug while in the DC Power Jack, you may be able to make the broken circuit traces touch each other, making a connection.
Eventually this fails to work.

Solution is to replace the motherboard. With this type of bad design the problem will reoccur.

This link is for the Acer Aspire 4520 Service Manual.
It is free.

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

As you can see there are many service manuals listed for Acers.
Scroll down with your eyes to the second Aspire listing. (Starts with 1200, 1300, 1310, 1350, and so on)
Scroll across the third line down, until you come to - 4520
Click right on 4520

This is a PDF file download. After you click on 4520, you may not see anything happening for a few seconds. The file is downloading in the background.

Advise letting the file download all the way, before looking through it. You might break the download connection.

If you wish to save a copy to your computer, go up to the top header, and click on the Floppy Disk icon.
This is the second icon from the left.

If you hover your mouse cursor over the icon, it will briefly reveal, 'Click to save this to your computer or another location'

After you click on the icon a small window comes up.
Save a copy...
Down in the Save a copy box you will see -
File name:

In the box to the right of File name, you will see -
aspire 4520 1220 4520g 4220g

Advise put your mouse cursor right after the g in 4220g, Left-click Twice, then make one space with your space bar.
Now type - Service Manual

Makes it much easier to find.
If you save it to your computer, you won't have to download it again. You can also burn it off to CD disk, and free up space on your harddrive.

I haven't worked on the Acer Aspire 4520 series yet.
The DC-in jack, (DC Power Jack) is on the Right side at the rear. (Page 17)

Looking at the Board Layout, Top View, on Page 12, you can see the DC Power Jack.

Come down below the 1 with the red small rectangle. Look straight to the left of the Half Moon hole, with the two top corners cut off. The DC Power Jackis on near the edge of the motherboard. (Board)

(You can click on the + sign in the top header, to zoom in)

On Page 13 you're looking at the Bottom view of the motherboard. (Board)
The little silvery dots are solder joints.

Your motherboard design does not follow Item 3,
I listed above.
You have a broken DC Power Jack, or cracked solder joints.

My 4520 Acer Laptop will not charge and will not work on AC power alone.......


You First need to test your AC Adapter Cord...
You can test if you have a secondary known working one.. plug that one in to see if same issue occurs.. OR you will need to test the AC Adapter using a multimeter (available at any home improvement store for under $7).. When testing the Plug End on the AC Adapter - Hold The Negative Test Prod Of the Multimeter to the Outer Side Of the Plug Tip, and Put The Positive(red) Test Prod Inside The Plug Tip... See If You Have Power Through The AC Adapter Tip... You Might Need To Slightly Wiggle The Cord Near The Tip End To See If THere Is A Short In The Cord....

If Cord Tests Good....

You Will Need To Replace The Laptops DC Jack...
The DC Jack is the port where your AC Adapter Plugs into on the laptop..

Your Faulty DC Jack Would Need to be desoldered, the motherboard cleaned of all old flux, Re-Tin The Contact Pads and then Resolder a New DC Jack Onto The Motherboard...

My Aspire One Netbook doesn't charge the battery


check the ac adapter, the plug on the end may be bad
also the pin in the dc jack ,if you can move this pin
just a little bit, the connection can be broken
new jacks are cheap , if you want to do this yourself
you must take apart

I have an Acer Aspire 4520 and the piece that connects the power cord on the inside of the laptop is broken. Do I have to buy the whole bored or can I just buy the piece that the part is connected to?


that requires dismantling the laptop, get to the power supply part, and replacing the jack. after you are done reassemble it. easy. if you cant do it, visit your local service center.

How do i clean a laptop keyboard


Hey,

its not a easy task.

I think you need to take it completely apart to get inside, the coffee most likely got inside the keyboard and is causing the problem.

all the keys need to come off, then look at it and see if you take take it apart, it might be glued together.

Not a easy fix.

You need to get inside to clean it, but in the process you might make it useless, and then how to get it back together.

I feel you will do better with a brand new keyboard.


Let me know if you need anything else.


Thanks,
Ekse

Bluetooth power


Hey,

to turn it on just press the button or pull the switch, if noting happens or the blue light doesn't light up and the computer doesn't react, it basicly means the computer didn't come with a build in bluetooth device, but has the option for the customer to later install one in the expasion slot inside the laptop.


Let me know if you need anything else.

Maybe it's your power supply, I suggest you get a voltmeter and check the voltage on the power supply.
