SMP and APM (advanced power management) are known not to work well together. You may be able to get it to work by playing with the APM settings in your BIOS. If not, doesnt seem like too much hassle to just reach down and hit the power button...

shutdown
SHUTDOWN(8) System Manager's Manual SHUTDOWN(8)
NAME
shutdown - graciously close the system down
SYNOPSIS
shutdown [-hrRmk] [-x code] [time-specification [message]]
DESCRIPTION
Shutdown is a program which allows a system operator to close down the system in an nice way. Shutdown informs the users why and when the
system is going down. This warning is issued 10 minutes before shutdown time and every minute in the last 5 minutes. At this time (5 min-
utes), shutdown creates a file /etc/nologin to prevent new users from logging in.
Shutdown keeps a logfile of shutdowns. Every shutdown is registered in /usr/adm/wtmp, if this file exists. After these actions, a call is
done to reboot(2) which actually brings the system down.
Time-specification may be something like 15:00, 15.00, +15, or now for a shutdown at 3pm (twice), 15 minutes from now, or immediately.
The message may be used to describe why the system is going down, it may also be typed on standard input with the -m option.
OPTIONS
-h This flag prevents the system from rebooting after the shutdown. The system can now be powered off. This is the default.
-r This flag indicates that the system should reboot after shutting down.
-R Reboot the system by resetting it. Normally the kernel will try to return to the Boot Monitor. With -R the system will receive a
hardware reset.
-x code
Halt the system and let the Monitor execute the given code as if typed at the monitor prompt. You can for instance use -x 'boot
hd0' as a very fast way to reboot "from the top."
-m Allows the operator to type a shutdown message on standard input, that will be added to the messages displayed on all terminals.
-k This option gives the possibility of terminating an already started shutdown. This is only possible if shutdown time has not yet
arrived.
-C Check if the system crashed. This option is not used at shutdown time, but at reboot time. It tells if the file systems should be
checked by testing if the last entry in the wtmp file is a shutdown entry. (A crude replacement for a file system clean flag.)
FILES
/usr/adm/wtmp, /etc/nologin, /usr/adm/authlog
SEE ALSO
reboot(2), wall(1), halt(8), boot(8).
