Under ACPI, the operating system directs all system and device power state transitions.  The 
operating system puts devices in and out of low-power states based on user preferences and 
knowledge of how devices are being used by applications.  Devices that are not being used can be 
turned off.  The operating system uses information from applications and user settings to put the 
system as a whole into a low-power state. 

Table 10 lists the power states supported by the boards along with the associated system power 
targets.  See the ACPI specification for a complete description of the various system and power 
states. 

(Note 1)

G0 – working 
state 

S0 – working 

C0 – working 

D0 – working 
state. 

Full power > 30 W 

G1 – sleeping 
state 

S1 – Processor 
stopped 

C1 – stop 
grant 

D1, D2, D3 –

specific. 

5 W < power < 52.5 W 

G1 – sleeping 
state 

S3 – Suspend to 
RAM.  Context 
saved to RAM. 

No power 

D3 – no power 
except for 
wake-up logic.

(Note 2)

 

G1 – sleeping 
state 

S4 – Suspend to 
disk.  Context 
saved to disk. 

No power 

D3 – no power 
except for 
wake-up logic.

required. 

No power 

D3 – no power 
except for 
wake-up logic. 

Power < 5 W  

(Note 2)

 

G3 – 
mechanical off 

AC power is 
disconnected 
from the 
computer. 

No power to the 
system. 

No power 

D3 – no power for 
wake-up logic, 
except when 
provided by 
battery or external 
source. 

No power to the system.  
Service can be performed 
safely. 

Notes:  

1. 

Total system power is dependent on the system configuration, including add-in boards and peripherals powered 
by the system chassis’ power supply. 

2. 

Dependent on the standby power consumption of wake-up devices used in the system.
