Does the laptop come on when you plug in the mains and take out the battery? If it doesn't then it could be a faulty power switch.

Problem description:The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause:1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution:1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.

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.

My Acer Aspire 9805WKHi wont turn on past the main acer start-up screen after my battery died. I didn't realize it wasn't plugged into the ac adapter so it was running only on battery.


Try taking out the battery and just plug in the ac adapter and see if it powers on that way. If it does use it that way for about 30 minutes then shut down. Put the battery back in, and keep it plugged in and wait about 30 minutes before you turn it on. This should refresh the battery enough to start charging.

I have an Acer Aspire 3610 notebook. It wont charge


How old is your battery? When you use your laptop, do you run it on just the battery or do you use your a/c adapter and battery? If you're going to use your laptop for an extended period of time, it's recommended to remove the battery and run off of a/c power alone. This helps to extend the life of your battery. Over time, using both a/c and battery will cause your battery to charge/discharge, which dramatically shortens the life of the battery.

You may simply have a dead battery.

Another alternative is that you have a bad power unit, which is what the a/c adapter plugs into on your laptop. My guess is that you most likely have a dead battery.

I HAVE A ASPIRE 5520 IT WONT START THE FAN STARTS AND THE DVD BUT IT JUST KEEPS ON LOPPING


I had the same problem but what you can do is...

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
  8. If its not the batery or AC adapter you might have to send it to Texas, just go to www.Acer.com

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.

If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?
