My acer aspire one will not charge and does not work when plugged in, is there any other way to charge it until I can get a new ac adaptor?


There is a known issue with a BIOS bug in some of the Acer models that it prevents charging. Try upgrading the BIOS from Acer online to the latest version following the online instructions. But you might have to borrow a charged battery from someone first if your battery is already completely dead now.

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.

It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

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.
