I tried adding the option earlier and had no positive results. I did 
grab the kernel for FC2 from the OS directory and installed this 
version. The results were that the computer would shutdown and poweroff 
with the kernel-2.6.5-1.358. This isolates the problem specifically to 
the kernel and not to other operating system functions. Also, since my 
computer is not that old and the BIOS was upgraded with a version from 
April 2004, the code in BIOS should conform to whatever caused the 
breakage for ACPI power-off. An option for acpi=power-off-legacy should 
be added to the kernel, if these BIOS settings do not conform to the new 
linux kernel or industry standards. I guess HP should unbreak the BIOS 
for acpi power-off also.Thanks for the acpi=ht suggestion. acpi 
power-off is all that is noticably broken. We need some option that 
addresses this problem specifically.

Thanks,

Jim
