Re: [CentOS] SOLVED - Shutdown/poweroff does not power off machine

Finally moved that machine over to CentOS 5.5 - and tried the acpi=force....

It worked!

Thanks again - that is awesome!!!!

No, I'm not the OP. But, I found a solution for my system.

During boot, I noticed an error line -- "BIOS fails cutoff age - ACPI might not work. Use acpi=force to fix."

So I did; the machine now actually turns off after shutdown.

Great work, Michael! Where did you insert/type in "acpi=force"?

In /boot/grub/grub.conf, there is a line (there may be more) that begins with 'kernel' - put it at the end of that line.
