XP Shutdown with AT Power Supply

How do I force XP Pro to display the "It is now safe to switch off your computer" screen when shutting down an ACPI-HAL computer which has an AT power supply? Yes, this is the opposite to what people normally want!
I'm looking for a simple answer which does not mean re-installing XP (i.e. to install with a Standard-HAL).

This article was previously published under Q313290
SYMPTOMS
When you try to shut down your Windows XP-based computer, the computer may stop responding (hang), and you may receive the following message:
It is now safe to turn off your computer

CAUSE
This behavior occurs on computers that support the Advanced Power Management (APM) feature. If you use a computers that does not load an Advanced Configuration Power Interface-compliant (ACPI-compliant) hardware abstraction layer (HAL), you receive this message when the shutdown procedure is complete. When you use an ACPI-compliant basic input/output system (BIOS) with the ACPI HAL, the operating system can turn off the power supply.
RESOLUTION
To resolve this behavior:
Click Start, and then click Control Panel.
In Control Panel, click Performance and Maintenance, and then click Power Options.
Click the APM tab.
Check to select the Enable Advanced Power Management Support check box, and then click OK.
