How are you sure that the power is getting through? Is the AC light on the computer on steady? Does it blink if you bump the connector?

So often the jack of the adapter or within the machine fails. Often if the jack feels loose on the computer, it is bad.

However, if none of that applies, I would go into the control panel and look at all the power settings to see if anything is unreasonable. Similarly, I'd look at the BIOS settings. (You may have to hit a particular key, like F10, when the machine boots --- there should be information on the screen, in the manual or at the Acer site.)

If that doesn't turn up anything, I would check the BIOS version and carefully follow the instructions to load a newer version if one is available or reload the previous version. Why? I don't exactly know, but when I had a Sony VAIO machine witih similar symptoms tech support suggested this and it did work.

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.


So your saying the charger will charge the battery, as long as the laptop is off...But when it is charged, you remove the ac adapter, start up the laptop, running on battery power alone, then hook the ac adapter to it, and the laptop cuts off..???

My Acer aspire 4935 is not recognizing the AC adapter. When ever I shutdown the system and connects the AC adapter, it works and the charging LED lights up. Once I press the power button to boot the...


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.

The battery is not charging


Hi

Turn the Acer notebook off by pressing the "Power" button. Remove any power sources connected to the notebook. If the notebook is open, close it.

Flip the Acer upside down and place it flat in front of you. Slide the battery locking mechanism to the right. The locking mechanism is diagonal to the lower left corner of the battery. While sliding the mechanism, slide the slimline battery out of the battery bay.

Insert the AC power adapter. The AC power adapter outlet is located toward the middle of the right side of the notebook. Attach the other end of the power adapter to a functioning electrical outlet. Open the laptop. Turn the power on. If the Acer notebook powers on, the AC power adapter is properly working. Replace the AC power adapter if the laptop does not turn on. Remove the AC power adapter and turn the notebook off.

Inspect the slimline battery. Look for signs of damage such as dents and corrosion. If the battery contacts appear to be dusty or have residue, gently clean them with an alcohol wipe or cotton swab dipped in rubbing alcohol.

Re-install the battery by sliding it back into the battery bay. You may hear a click or snap when the locking mechanism locks the battery firmly into place.

Plug the AC power adapter into the laptop. Leave the power adapter in the notebook for eight hours so the battery charges.

Remove the AC power adapter. Power on the Acer notebook. If the notebook does not power on, the slimline battery must be replaced. If it does turn on, the battery did charge.

It just wont turn on i have checked the power lead and its ok its an acer aspire 5050 laptop


Hi. I would suggest you double check the ac adapter if the powercord is properly attach to it ot also you might want to try powerdraining or powercycling your computer. To do this you must turn off your laptop then remove the battery and unplug the ac adapter then press and hold the power button for 20 seconds while the battery and ac adapter is out, after that place back the battery and plugin the ac adapter and try turning on your laptop, if this doesnt work then try power draining it again and just use the ac adapter or just plug it in without the battery then try again turning it on. If it still has the power issue then try a known good ac adapter so that you could double check that it is not an ac adapter issue or a battery issue. If all that trouble shooting step doesnt work then you could also try calling acer tech support to help you on your issue if your machine or laptop is still under warranty they would help you fix it by sending that laptop to there depot without any charge. Hope this Helps

Acer aspire laptop won't charge


Hi,
First of all you have to determine whether it's the battery, charger or the laptop itself.
Remove the battery and boot the laptop on AC power only, if the laptop boots up you can rule out the charger and the laptop, you may need a new battery if that is the case.



Regards.

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.

Acer Ferrari 4000 Laptop not working on AC current.


If the AC adapter is not working, does the battery not get charged when it is in the laptop? In other words, is there some other way the battery is being charged? Is it that the PC will not operate when the battery is out of the machine and the AC adapter only is present for power? If so, make sure that the power profile you are running under is set to allow the adapter to power the machine. To check this power setting (in XP), right-click on a blank section of your screen, choose Properties > ScreenSaver > Power. There could also be an issue within the Acer software utilities; particularly, it would be recommended to verify the settings in ePower Management.

If you still do not see any issues after these steps, please take the steps detailed here: http://www.acerpanam.com/synapse/forms/portal20.cfm?recordid=1125&formid=3390&website=AcerPanAm.com/us&siteid=7293&words=all&keywords=&areaid=7.
This will help to ensure that there is no issue with the adapter itself; though, if the battery is charging using the adapter it appears that is not the problem.

Beyond this, I would say that the primary determinant lies in how the battery is being charged. If it is being charged with the usage of that adapter, then the problem would apparently lie with the connection of the adapter inside the notebook, for which a qualified technician will be required. If your machine is still under warranty, and it is determined there is some type of faulty connection, that should be covered.
