Looking for BIOS updates for Aspire One ZG5

Nothing major. My battery refuses to charge (and he replacement doesn't charge either so....)


Seems the best advice on the ZG5 is to flash the BIOS but I can't find a BIOS update on this site - or I'm blind.


Any help would be appreciated

    Have you measured the charger's voltage output yet? Jack E/NJ

    OK. Try this link http://www.acer.com/ac/en/US/content/drivers . Enter aoa110 for the model. Click on BIOS. Then try to recover that BIOS version. If you can't recover it via the OS, then try the Fn+Esc USB stick method by renaming the ROM file in the extracted DOS subdirectory to JAL90x64.fd  . It should be the only BIOS file in the USB root directory.   Jack E/NJ

    the correct filename is zg5ia32.fd

    the process is the following:

    Create a recovery USB drive to update the Bios on the unit.

    The specific steps to perform this recovery with the USB drive are:

    1.    Download & Extract BIOS_Acer_3310_A_AOA110 & AOA150
    (found in  https://www.acer.com/ac/en/US/content/support-product/60?b=1)

    2.    Rename the Bios name from 3310.fd to zg5ia32.fd

    3.    Copy zg5ia32.fd and Flashit.exe to USB flash drive.

    4.    Start the restoration process:

    §  A. Plug the AC Adapter into the unit.

    §  B. Insert the USB flash drive into a USB port.

    §  C. Press and Hold down the Fn and the Esc keys together.

    §  D. Keep these keys held down and press power.

    §  E. When the unit’s power light comes on release the Fn and Esc keys.

    §  F. After the keys have been released the power light will start to blink.

    §  G. Let the unit run and after approximately 1 to 7 minutes, the unit should reboot.

    §  H. Video should now be restored.
