Looks like your power adapter for your laptop is short-circuited. Replaced it with a new adapter.

Hope it helps.

    I have exactly the same problem, but on battery it also seems to shutdown in windows normal mode.
    It runs fine in safe mode.
    replaced all cooling paste, cleaned fan/heatsink, replaced harddisk, measured powersupply, nothing helps. probably faulty mainboard

    Aspire 6920G, asumption, you are on OS Vista, update your Windows , Device drivers & Bios vesions to latest, link @"http://support.acer-euro.com/drivers/notebook/as_6920G.html"
    ***Caution updating the Bios is not for any novice Users
    @bastion, remove the battery and run the laptop from the direct power source, failing battery do cause it to shutdown.

Hi, my laptop crashes when the ac adaptor is plugged in yet it will charge the battery fine when the laptop is shut down.


Problem description: The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause: 1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution: First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.
If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

BOOTING PROBLEM


If the computer will not power on:

  1. Make sure the power cord or AC adapter is plugged into the computer and into an electrical outlet that is live.
  2. If it is plugged into a power strip or surge protector make sure it is powered on.
  3. Try using a different electrical outlet.
  4. Check voltage setting on power source (AC Adapters are auto switching).
  5. Perform a power reset on the computer.

To perform a power reset:

  1. Unplug and remove the AC adapter and battery, or power cable from the computer.
  2. Press and hold the power button on the computer for about 30 seconds.
  3. Release the power button and plug the AC adapter and battery, or power cord back into the computer.
  4. Press the power button and see if the computer powers up.
  5. If that does not work, try a different AC adapter, battery, or power cable and repeat these steps.

If the problem persists the computer may need service. You may need to contact Acer support.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

I am sure its totally fault of your OS. Becouse some when ac working well, some where battery. your OS does not recognised your power control properly. Try to use single OS and get batter result. if done thumbs me.

My acer 4520 laptop shuts off while using it. why? cant seem to complete any task without powering it back on.


Hi,

This may sound stupid, but it could be as simple as your battery being low. If the battery is charged and it is still shutting off on you, the battery may need to be replaced.

One way to verify this would be to remove the battery, and plug the computer into the AC Adapter and see if it runs properly.

If it works fine, then you know that there's a problem with the battery. If not, then it may be something more serious like a motherboard issue. If it gets to that point, I suggest you take it somewhere that it can be physically looked at.

Hope this helped :)

Power cord attachment into the back of computer seems worn, it wants to run off battery instead of recharging through power supply


Either Have A Failing AC Adapter, Or A Failing DC Jack
you can test the AC Adapter using a multimeter (available at any home improvement center for $6)..
The DC Jack Would Need To Physically Be Checked To See If It's Faulty... which would intail removal of all parts down to the motherboard and visually inspect the DC Jack (the port where the Charger Cord Plugs into)

Says plugged in not charging


Take out the battery and make sure you can turn on the laptop with just the AC Adaptor hooked up.

If you can then you know the AC Adaptor is good. Try another known good working battery in the laptop, if the battery charges then you know that the old battery is bad.

If the laptop doesn't charge with a know working battery or a new one then you know that the motherboard is bad.
