534	ThinkCentre A57 does not power off with ACPI 3.19.14/15, needs additional tool to succeed	herwigb	David Azarewicz	"This a !ThinkCentre A57 with a Core2Duo. Power off used to work a year ago, but stopped with later revisions of pre-ACPI 3.19.02.

Power Off also does not work with ACPI 3.19.11/14/15.

I tried:
||CONFIG.SYS||CPUs||Result||
||PSD=ACPI.PSD (no switch)||2||power off does not work||
||PSD=ACPI.PSD /VW||2||power off does not work||
||PSD=ACPI.PSD /MAXCPU=1||1||power off works||
||PSD=ACPI.PSD /VW /MAXCPU=1||1||power off works||

I did some more testing and found out that in SMP mode (2 CPUs on) if I turn off the second CPU using [http://reocities.com/SiliconValley/pines/7885/Download/DownloadCPU2.html CPU/2 utility from Roman Stangl] before shutdown, the machine is properly powered down.

Note: Also power management does not work with this machine (will be a separate Ticket)."	defect	closed	major	Release 4.00	ACPI PSD	3.19.15	fixed
