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.
