I have a hunch that your SSDT is broken.  In fact, it looks little 
unusual.  Have you tried to update your BIOS?  You seem to have two 
year old BIOS and it claims it only complies with ACPI 1.0, which has 
been dead for many years. :-)

BTW, 'holding down power button for a few seconds' performs emergency 
shutdown sequence, which is usually done without ACPI intervention.
