Battery will not charge

My Acer A0A150 went dead a while back but by re-flashing the BIOS with a newer version as per solution 3 (FN & ESC method) it came back to life. The same ACER battery stopped charging yesterday and I have just managed to replace the BIOS with 3310, using the windows based InsydeFlash program that is downloaded with the BIOS upgrade, the FN & ESC method was installing a version 3301 instead of the 3310, therefore not allowing the battery to charge. Acer Aspire Ones seems to have alot of BIOS Issues, I now have one USB stick with only ACER BIOS reboot software on it just for the occassions. Hope this helps.

I solved the problem by updating to 3310 (this is now a windows solution, so all you need to do is read the readme file in the zip, run the run the program and let it do its thing).
I also pulled the battery and power plug, and held down the power button for one minute as mentioned above, but not sure if that was a contributing factor.

I went to the Acer web site and for the Aspire One. It said that if you do not have BIOS version 3309
it will not charge the battery if it gets too low. I had version 3305. You can find the version on your
laptop by clicking on system information. Look at BIOS version. From the Acer web site you can
download the program to flash your BIOS up to 3309. The only kicker is that you need to put it on
a bootable thumb drive, boot from the thumb drive and run the flash program. You can go to this
web page for how-to on the bootable thumb drive http://www.bay-wolf.com/usbmemstick.htm

With the flash program comes step by step instructions. Not the best translation to English but
it was good enough to do the job. What can I say, I did it, it worked, it took about 15 minutes
total.

Hope this helps

If the battery discharges below a certain charge level, it may not be able to be recharged unless the System BIOS is flashed to revision 3309 or later.

If the battery will not charge, please ensure that you have the latest BIOS before fore calling the Acer warranty support line. Updating the BIOS will require a USB flash drive to store the BIOS information on during the update. To perform the update to the BIOS:

1. Go here and download and extract the latest BIOS for the netbook.
2. Rename the BIOS file from 3309.fd to zg5ia32.fd.
3. Copy zg5ia32.fd and Flashit.exe to USB flash drive
4. Ensure that the AC adapter is plugged in.
5. Insert the USB flash drive into a USB port.
6. Press and Hold down the Fn and the Esc keys together and press the power button.
7. When the unit's power light comes on release the Fn and Esc keys.
8. After the keys have been released the power light will start to blink.
9. Let the unit run and after approximately 1-7 minutes, the unit should reboot and the BIOS will be updated

Note: These instructions are only for the Acer Aspire One AOA-110 and the AOA-150 netbook series and should not be performed on any other model Acer Aspire One.
This worked for me, just make sure the 2 files are in the root directory of Flash Drive other wise your computer will not find them when it boots up using the FN & ESC keys.
Hope it works for you. If it does, then spread the word!

Power reset the unit, unplug it pop out the battery and hold the power down for a minute, put the battery and ac adapter back in and start her up, the mobo was probably still holding power when the battery died causing a "hiccup"in the system, this should resolve or at least help a little

NEBaptist's solution - namely BIOS upgrade to 3310 (it is no more 3309) - fixed the problem. Thanks a ton.

Special thanks to samurai33 who listed this solution foremost. And thanks to all those contributors who uploaded their feedback confirming BIOS upgrade as the right solution for this problem.

UPDATE !!!!
There is now a windows based flash utility to update the bios to 3010. It is downloaded from the acer support site.

The problem was solved using both samurai33 and Setabocle solutions. Battery now charging. Thanks guys.

Setabocle's solution strongly recommended


I didn't use the netbook for roughly about...a week and a half or thereabout and when I plugged in the ac adapter to charge the battery today, the battery charging icon would not appear at all. I left it 'charging' for an hour but when I unplugged the adapter cable, the unit went dead. Panic!! Googled my way through a few solutions, tried them, without much success and I nearly gave up on it when I came across Setabocle's trick! You're the best mate!! Anyone having the same problem, go do it now, it WORKS!

Carried netbook the service center.
They replaced the battery. Perhaps the factory defect.
If Netbook starts without a battery and you have bios version 3309. Take the battery to a service center for replacement before the end of the guarantee.

thank you setabocle!!! it worked!!!

I had the same problem. Make sure your battery is in the locked position. Then it will start to charge.

I love you guys. My battery is now charging. :D :D :D

I did the BIOS flash using the flash drive which worked but the battery still wouldn't charge. I almost stopped there just happy to have the machine functional again but dug a little deeper and performed the Insideflash bios update from inside windows which STILL didn't get the battery charging again. Finally pulled the battery and plug, held the power button for 2+ minutes, reinstalled battery and plugged in and turned on and Viola we have a charging battery once again. Thank you to all contributors you guys ROCK!!!

I have an acer aspire one AOA 150 and I have wiped the linux vrsion off it that it come installed with and I have put Ubuntu on it, can I update the bios still using this method?

Hi , I had a problem with my acer aspire one AOA 150 where the battery would'nt charge but i could use it on the mains charger.
Since trying solution #5 it's gone completely dead and i can't switch it on, even with a charged battery from another net book.
Has anyone got any suggestions?.
