Battery will not charge

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.

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

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

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!

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.
