G2/S5 S5 – Soft off.
Context not saved.
Cold boot is
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.
1.12.1.2 Wake-up Devices and Events
Table 9 lists the devices or specific events that can wake the computer from specific states.
Table 9. Wake-up Devices and Events
These devices/events can wake up the computer… …from this state
LAN S1, S3, S4, S5
(Note)
Modem (back panel Serial Port A) S1, S3
PME# signal S1, S3, S4, S5
(Note)
Power switch S1, S3, S4, S5
PS/2 devices S1, S3
RTC alarm S1, S3, S4, S5
USB S1, S3
WAKE# S1, S3, S4, S5
Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On
will enable a wake-up event from LAN in the S5 state.
NOTE
The use of these wake-up events from an ACPI state requires an operating system that provides full
ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake
events.
