With this http://ubuntuforums.org/showpost.php?p=2260791&postcount=10 I solved the shutdown issue. The computer halted during shutdown and did not power off.

Summary:

Step 1: Add

Code:
apm power_off=1
to your /etc/modules

Mine already had an entry so I just added the code directly below it and then hit enter to add 1 blank space at the end of the file. Basically it should look like this:

Code:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
apm power_off=1

You may have other modules like fuse or p4_clockmod or whatnot. That’s ok. So long as you put in “apm power_off=1″ and keep a blank entry at the end of the file you should be ok. The blank entry might not be needed, but it was there when I started so I kept it.

Step 2: Add

Code:
acpi=off apm=power_off

to your /boot/menu.lst so it looks like this:

Code:
## ## End Default Options ##
