Computer won't automatically power off

[verdstein]

On this new system, I've been wondering why I get the "it is now safe to turn off your computer" message instead of an automatic shut down. Now, I gather that, for some reason, Win XP Pro did not recognize the ACPI compatibility of my motherboard when I installed the system. When I run apmstat.exe from Microsoft Support tools to check compatibility, I get the message:
"APM requires HAL support, this computer does not have that support
APM will not work on this computer, at all."
Also, none of the APM drivers are installed.
From what I've read, the only way to fix the problem would be to reinstall Win XP, and I wonder if that would even work, given that it didn't work the first time through.

Any thoughts or suggestions?

On some motherboards, there is an option to enable/disable ACPI in the BIOS, did you double-check to make sure it's enabled? Also, I'm pretty sure you will need to reinstall to get the ACPI kernel.

Verd,

Are you actually running an ACPI HAL?

If so, try going to Device Manager and View Hidden Devices.
You should see something call NT Legacy APM yadda-yadda something.
Right click it and enable it.
You will be good to go!

KGB, I don't think so. When I go to device manager and select "computer" it shows "MPS Uniprocessor PC." When I view hidden devices, there isn't any entry for NT Legacy APM.

Supa, I've looked around in the BIOS for something like that and I can't find anything. I've emailed Gigabyte tech support, so hopefully they will let me know if I'm looking in the wrong place.

Does the ACPI kernel have any advantages other than the automatic power off? Is it worth reinstalling?
