I have a machine with Windows 2000 working with ACPI. When I shutdown the computer, it turns itself off. I want to prevent this, because I control the power supply from an external switch.

Is there a possibility? I don't want to deactivate the hole ACPI because I fear it could crash the hole system.

thx for any suggetions

Try editing this registry key ..

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"PowerdownAfterShutdown"="0"

No you can't do that without disabling ACPI.

AND if you turn ACPI, windows will no longer boot... I've still not found my way around that little problem without reinstalling windows...

but just turn off ACPI when you have a handy windows 2000 CD lieing around and reinstall the darn thing.  Don't forget to load the same service pack you had before too... to check your service pack, right-click my computer and go to properties, or go to System in the Control Panel, and it will be listed under the General tab in the system section.

Hope this helps!
