Oddly enough, the procedure to get APM poweroff working in Windows NT 4.0 seems to only apply to single CPU systems.

If you happen to have a dual CPU system that's most likely going to be using an ATX power supply, attempting to power off after shutdown may fail outright. Essentially, the batch script the user executes from Windows NT is used to set things up to automatically reboot into MS-DOS, leaving a dummy file there for its AUTOEXEC.BAT to check. Upon checking for the existence of this dummy file, MS-DOS deletes it, restores the normal boot configuration, and then powers off the system as directed. Booting into MS-DOS normally does not power off the system.

Get this working yourself using this guide.
