Sony Vaio VGN-N325 ACPI Problem

I am a new Linux user, Used to mess around the various distros,
knoppix, redhat & mandrake. Using Pcs for 22 years from MSDOS &
Win 3.1. I have just been using Ubuntu 8.04 Hard Herron for 2 weeks now
on my Sony vaio vgn-n325e laptop and I have serious acpi problems.
Machine wont shutdown without hard power-off, restarts fine, cant see
battery state or ac adapter states. Please help, I have completely
formatted vista, I am so impressed with the system responsiveness but
need full laptop compatibility.

These are more indepth specs

I have extensively researched this question through google, this forum
and other sources, I have also sought the expertise of a few
individuals. I even submitted my dst file to a forum. It is evident
that Sony Vaio has an ACPI mounting issue (not sure if that is the
right terminology). In order to install Ubuntu I had to select the boot
option install with ACPI workaround, I thought this would have just
gotten me over the installation issue but it seems to have other
repercussions. I can boot the recovery mode kernels fine and power
down/suspend/resume etc without a hard powerdown. Whenever I do a
normal kernel boot that is when I have to hard power down. I have
posted to several linux forums with little results.
