You'll need to replace the power jack.

Most shops / techs charge $75-100 but that depends on your location.

If you do itself it's about $10 for the jack.

You can get them on eBay fairly easy.

This type of repair is not covered under warranty.

Best of luck!

I reset my surge protector and the computer wont power up. i think i need a new power supply. the power cord is working fine. Please let me know where i can find a power supply for the aspire...


The Acer Aspire L100 is a desktop computer powered by a special DC adapter and power cable. The computer's motherboard incorporates a fuse designed to prevent any power surges from damaging the computer. If the fuse burns out due to a power surge or for any other reason, the computer will no longer function. You can check the motherboard fuse for damage yourself, then take it to a trained technician for replacement if needed

Shut down the Acer Aspire L100 and turn the tower around.

Press the "On/Off" button on the front of the tower. If the computer will not boot and the fan does not turn on, the fuse may be burned out.

Unplug the power cord from the rear of the tower

Turn the tower on its side and remove the Phillips-head screws connecting the back panel to the Aspire L100's cabinet.

Pull out the motherboard assembly gently from the back of the cabinet. The internal fuse is located on the motherboard behind the DC power jack, which is to the right of the monitor jack

Let me know if this helped..

    Green light on. computer wont turn on


    Unfortunately, if the light is on, but the computer won't power on, it means one of two things. Either the power cord is broken in some way and no long sufficient to power the computer, OR the motherboard is dead. You can try to purchase a universal cable from Best Buy for instance, and then return it if it doesn't solve your problem. A motherboard repair would be best done through Acer themselves, although, it can cost over $300.

    My acer aspire 7520 will not start up, I push the power button and it keeps going on and off every 20 seconds.


    This is possibly a faulty power supply and a battery that is not being charged.
    You have a broken connector at the pc input, a broken cord at the strain relief.

    Acer aspire 6920 just went off yesterday abruptly. no power with or without the battery. no power when just using the power cord. I tried removing the battery and ressetting the power button ( no luck)....


    Take the battery out and short the pins. If this doesnot work than seems your power adapter is problem. It is not charging the battery. Check if your power adapter is OK. If it is ok than looks like the power jack pin is open. Take it to repair center to have the Jacks fixed

    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 ACER 5570z will not start up. When power cord


    You most likely have a broken DC Jack on the motherboard. Thus, the battery cannot get a charge and the power supply is not making a connection to the system board because of the broken DC Jack.

    Good Luck

    Acer 3680 ac pin broken


    That's really not advisable. At our shop we do socket repairs, I suggest finding someone local who specialises in laptops and asking them to replace it. You can get the sockets on e-bay, etc, if you wish to try it at home, though I don't advise it.

    Don't forget to take static safety precautions!

    Replacement part for charger plug in on laptop.


    The plug for the charger? its soldered into the motherboard. it requires a full disassembly of the laptop.

    Just need to find a replacement for it.
    you can try contacting http://www.acerparts.com/ with the laptop details for the power connector / plug
    you can also look for it on www.ebay.com

    computer repair shops should be able todo the job, really no need to replace the whole motherboard, just the plug. Also check is the cord of the power adapter broken? I had to take my power adapter, the black box in the middle of the cord from the wall to the laptop, one cable had came loose inside the power adapter, worked perfectly after I resoldered it in place.
