The problem for the Acer Aspire 3000 series is into the chipset battery, that comunicate to the PC through a serial protocol (probably I2C) to sent information, charge, status, etc.
Due to an ACPI bug, the battery module is not recognized by Windows. Bios upgrade doesn't solve the problem.
To solve the proble there are three ways:
- change the Hal driver to "PC standard"
- disable (not uninstall) the "Microsoft ACPI-Compliant Control Method Battery " and "Microsoft AC adapter"
- unplug the battery for 1 minute and re-plug it (with windows running).
The first metod work fine but Wi-Fi doesn't wok. All the rest of hardware yes, "Suspend" not possible, you must torn off the PC manally. Not Good!
The second is the right. It work only if your PC (HAL driver) is configured at "PC uniprocessor ACPI", see Microsoft documentation for help (HAL options after Windows Xp setup...).
The best way is to install a fresh Windows Xp, WITHOUT BATTERY INSERTED!!!. Windows configure it automatically in the right option.
After installion start Windows, important leave battery unplug,
then go to the device manager, expand "Batteries"; than disable "Microsoft ACPI-Compliant Control Method Battery" and "Microsoft AC adapter". It's fondamental to not disinstall them, otherwise windows re-install them at next boot!
Now you have a complete usable PC with ACPI enable (suspend, auto power off,...), windows does not comunicate with the battery, and the system doesn't freeze. The PC is also able to charge the battery and use it, the only unusable function is the battery status.
The battery infact is charged by hardware not by software. If you are in battery mode you can't now how charge remain.
I have an Acer Aspire 3005 WLMi, with the same bug and now i use it without problem.
