You may need to enable something in your BIOS along the lines of press the 
power button for 4 seconds in order to power off.

From the software perspective, I think you also need the acpibtn(4) device. 
(check your dmesg for that)

If your dmesg doesn't show a acpibtn device, apart from checking hardware 
setup (e.g. BIOS settings), I'm out of ideas.

Have you tried it? Just a short press on the button?

You could try uncommenting one of these in /etc/sysctl.conf

#machdep.apmhalt=1  # 1=powerdown hack, try if halt -p doesn't work
#machdep.kbdreset=1 # permit console CTRL-ALT-DEL to do a nice halt 

Also, check your BIOS settings.
