Power off is one of those BIOS + ACPI things. Do check for a BIOS update. Toggle between APM and ACPI if the BIOS permits. Not a great link but a start: http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface Better.. http://www.acpica.org/documentation/faq.php See the 'interpreter' bits and if available update yours (OS side of it).The CentSO man page for acpid makes this note.... and since you have a 'newer' processor do look into it.
