Hello,
You probably don't have to replace the part. On most Acer laptops, the DC power jack attaches to the mainboard with a cable. The power jack is usually held in place by a plastic bracket inside the laptop. This bracket is probably broken. Here's what I would do:

Open the laptop and find the bracket that holds the jack in place. It is probably broken, and you may have pieces of plastic rattling around. Find the plastic pieces and superglue them back in place, put the jack back into position and reinforce the back of it with a bit of hot glue. I have done this dozens of times in my repair shop. If this is not the problem, or you are not confident in doing this then take it to a reputable computer repair shop :)

Hope this helps!

Joe

SOURCE: Acer 5920-6474 does not power on

the problem lies with failed smd capacitors grounding out underneath the motherboard on the same side of the board as the cpu heatsink. if you look at the board with the heatsink/fan in the top right hand corner- the culprit caps are in the bottom right hand region under some see through plastic. they are labeled pc144 and pc145.

SOURCE: Acer Aspire 5920-6864 Is not turned on

this probleme is common among acer 5920, the probleme is with the motherboard that's of bad quality and workmanship. Acer should be ashamed to sell a PC with a faulty motherboard and should compensate all 5920's owners or replace with a better motherboard. 1000's if not millions are having the same probleme wich tell to anyone with a brain that Acer 5920 is a scam. good luck. x

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

AC adapter 4750z

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

Acer Aspire 5720Z will not turn on please help me

For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

There's seems to be a short where the AC adapter goes into the Laptop. Loose parts in that area of the Laptop where the adapter goes in. It won't turn on. Maybe it's the battery.

Unfortunately, this is a frequent issue with laptops. Being moved around frequently can cause the AC Adapter to pull at the DC Jack on the laptop. If it is loose, it can mean there is a broken connection within the laptop. What you can try is powering the laptop on with it plugged in and the battery removed. If that doesn't work, I'd recommend going to your local Best Buy and picking up a universal AC Adapter. If that doesn't work, you can always return it, even if opened.

2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.

3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.

4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

Acer 5920 aspire wont start

1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Pressand hold on the laptop’s power button for 10 seconds to drain the powerflea.

3. Connect the AC Adapter for laptop to a known good power outlet, check ACAdapter power LED if it is on. Try to sense if AC Adapter is not makinga bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter tothe laptop. Check if AC Adapter LED stays on when it is connected tothe laptop. If the LED stays on means the AC Adapter is fine. If the ACAdapter LED turned off check the AC Adapter pin that goes to the laptopAC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try topower on laptop. If no power LED comes on then this is motherboardproblem.

6. Before replacing the motherboard there is one checking needs todo. If you can open your laptop bottom part then good, do this whenlaptop is not connected to any power source. Try to reseat the laptopCMOS battery then try to power on laptop after, if still fails thenreplace motherboard. I hope this helps.

Ac adapter connection inside laptop doesnt work, light for battery charging will not turn on and will not charge

You adapter may be faulty, check it with a multi-meter, the voltage reading for a functioning adapter should be slightly higher than the voltage that is printed on the label on the adapter.
If you do not get a voltage reading then the adapter is faulty and you need to get a replacement adapter.
If you get a reliable voltage reading at the adapter plug, then connect it into the laptop and wriggle this plug. If the charge LED blinks. then the power connector on the laptop is loose/faulty and needs repairing.
