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 Power Down

 

VGA Power Down

 

PCMCIA Suspend

 

Audio Power Down

 

Hard Disk Power Down

 

Super I/O Power Down

 

 

Sleeping State (S4)

Also called Hibernate state. System saves all system states and data

 

onto the disk prior to power off the whole system.
