You don't say which distro or kernel you are using, which may help.
For what it is worth I had this problem a while ago. My Redhat box died and the only CD I had was debian. The new debian box (kernel2.4.18) would not power down automatically. I just loaded the apm module and things then worked as expected.
John,
my system is based on RH9, with the kde-redhat project inside using apt-rpm. However as shutting the machine off works with the exact same configuration only booting a different kernel (the 2.4.18 shipped with RH) I suspect some option/module must be set in the kernel to get this working. The "apm" module is loaded, and the "apmd" daemon from the RedHat system is started and runs without error.
My problem is that I don't really know what is supposed to make this particular feature work. Is it apm? When I read the docs about APM/ACPI it seemd all to be about battieries and other laptop-related matters, and my machine is just a standing desktop. So what software is it that is supposed to make this work?

APM = Advanced Power Managment ACPI = Advanced Configuration and Power Interface
It would be one of these options that would handle shutting down the power on your computer, most likely APM if you have an older BIOS. It does also take care of batteries on laptops, but it is Power Managment in general, not just batteries that it handles.
As to fixing your problem, you did say the APM module is loaded & apmd is running without errors, so my best guess is that your APM module is missing some option required for it to work right on your machine. Look through your kernel config and check a couple options that you think might have to do with this, such as "CONFIG_APM_REAL_MODE_POWER_OFF":
Use real mode APM BIOS call to power off
Use real mode APM BIOS calls to switch off the computer. This is
a work-around for a number of buggy BIOSes. Switch this option
on if your computer crashes instead of powering off properly.HTH, Conway S. Smith
