4.8.3.2
The SCI interrupt is masked. The firmware polls the power button status bit in the ACPI
hardware registers and sets the state of the machine in the chipset to the OFF state. The
mBMC monitors power state signals from the chipset and de-asserts PS_PWR_ON to the
power supply. As a safety mechanism, the mBMC automatically powers off the system in 4-5
seconds if the BIOS fails to service the request.
4.8.3.3
If an operating system is loaded, the power button generates a request (via SCI) to the
operating system to shutdown the system. The operating system retains control of the system,
and OS policy determines into which sleep state(s) the system can transition.
4.8.3.4
If an operating system is loaded, the sleep button generates a request (via SCI) to the operating
system to place the system in “sleep” mode. The operating system retains control of the system,
and OS policy determines into which sleep state(s) the system can transition.
4.8.3.5
If an operating system is loaded, the sleep button generates a wake event to the ACPI chipset
and a request (via SCI) to the operating system to place the system in the On state. The
operating system retains control of the system, and OS policy determines from which sleep
state(s) and sleep source(s) the system can wake.
4.8.3.6
The platform supports the following ACPI System Sleep States:
The platform supports the following wake up sources in an ACPI environment. As noted above,
the operating system controls the enabling and disabling of these wake sources.
Revision 2.1
ACPI S0 (working) state
ACPI S1 (sleep) state
ACPI S4 (suspend to disk) state
ACPI S5 (soft-off) state
Devices that are connected to all USB ports, such as USB mice and keyboards can
wake the system up from the S1 sleep state.
PS/2 keyboards and mice can wake up the system from the S1 sleep state.
Both serial ports can be configured to wake up the system from the S1 sleep state.
PCI cards, such as LAN cards, can wake up the system from the S1 or S4 sleep state.
The PCI card must have the necessary hardware for this to work.
As required by the ACPI Specification, the power button can always wake up the system
from the S1 or S4 state.
