Power Management

ACPI Mode	Power Management
Mech. Off (G3)	All devices in the system are turned off completely.
Soft Off (G2/S5)	OS initiated shutdown. All devices in the system are turned off
	completely.
Working (G0/S0)	Individual devices such as the CPU and hard disk may be power
	managed in this state.
Sleeping State (S3)	CPU in Stop Clock state
	VGA Suspend
	PCMCIA Suspend
	Audio Power Down
	Hard Disk Power Down
	Super I/O Low Power mode
Sleeping State (S4)	Also called Hibernate state. System saves all system states and
	data onto the disk prior to power off the whole system.
