Power States and Targeted System Power

Global States Sleeping States
G0 – working S0 – working
state
G1 – sleeping S1 – CPU stopped
state
G1 – sleeping S3 – suspend to
state RAM. Context
saved to RAM.
G2/S5 S5 – soft-off.
Context not saved.
Cold boot is
required.
G3 – No power to the
mechanical off system.
AC power is
disconnected
from the
computer.
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.

Wake Up Devices and Events

Table 10 lists the devices or specific events that can wake the computer from specific states.
Table 10. Wake Up Devices and Events
These devices/events can wake up the computer...
Power switch
RTC alarm
Wake on LAN technology connector (optional)
PME#
Modem (back panel serial port A)
(Notes 3 and 4)
USB

PS/2 keyboard
Notes:
1. S5 events are supported only on PCI bus connector 2.
2. For the Wake on LAN technology connector and PME#, S5 is disabled by default in the BIOS Setup program. Setting
these options to Power On will enable a wake-up event from LAN in the S5 state.
3. Wake from USB requires the use of a USB peripheral that supports Wake from USB.
4. To enable Wake from USB, set the Wake from USB jumper to enabled and set ACPI Suspend State option to S3 in
the ACPI Submenu.
5. To enable Wake from PS/2, set the Wake from PS/2 jumper to enabled and set ACPI Suspend State option to S3 in
the ACPI Submenu.
