  • Hi,

    There was indeed an Acer BIOS update, which I installed. By itself, it didn't fix the problem. I had to:

    1. Install the BIOS.
    2. Reboot, log back on, delete the "Microsoft ACPI-Compliant Control Method Battery"
    3. Shut down.
    4. Removed the battery, unplug the power, waited a few minutes, tapped on the keyboard with voodoo chicken feet.
    5. Plugged it back in without the battery, booted it
    6. Logged on, deleted the ACPI driver again.
    7. Plugged the battery back in (hot, not shut down)
    8. Rescanned for hardware changes.
    Don't know if all the steps were necessary (except for the chicken feet of course), but that fixed the problem.

  • uninstall the battery in the device manager, reboot and let Windows install the battery again.

  • I have an Acer Ferrari One netbook with this problem, and uninstalling / reinstalling the battery driver didn't solve it. 

    I've uninstalled the "Microsoft ACPI-Compliant Control Method Battery", removed the battery, rebooted, reinstalled the battery, rescanned the hardware, the driver reappeared, to no avail. I cannot uninstall "Microsoft Composite Battery." When I scan for new hardware changes, even if the battery has been removed, the ACPI compliant driver reappears, and the battery still isn't charging. It's down to 2% now, and its five-hour battery life is, for the moment, history.

    Thanks, Sean

  • Hi Sean,

    some users reported, that they must update the BIOS to fix it. So go to the Acer Homepage and look for a BIOS update.

  • Hi,

    thanks for the feedback. This is helpful for other Acer Ferrari users.
