2.19 Power Management
The POS-8520 motherboard supports Advanced Configuration and Power Interface
(ACPI) Specifications Revision 1.0. The ACPI specification, revision 1.0 reads:
The ACPI interface gives the operating system (OS) direct control over the power
management and Plug and Play functions of a computer. When it starts, the ACPI OS takes
over these functions from legacy BIOS interfaces such as the APM BIOS and the PNPBIOS.
Having done this, the OS is responsible for handling Plug and Play events as well as
controlling power and thermal states based on user settings and application requests. ACPI
provides low-level controls so the OS can perform these functions. The functional areas
covered by the ACPI specification are:
• System power management - ACPI defines mechanisms for putting the computer as
a whole in and out of system sleeping states. It also provides a general mechanism
for any device to wake the computer.
• Device power management - ACPI tables describe motherboard devices, their power
states, the power planes the devices are connected to, and controls for putting devices
into different power states. This enables the OS to put devices into low-power states
based on application usage.
• Processor power management - While the OS is idle but not sleeping, it will use
commands described by ACPI to put processors in low-power states.
• Plug and Play - ACPI specifies information used to enumerate and configure
motherboard devices. This information is arranged hierarchically so when events
such as docking and undocking take place, the OS has precise, a priori knowledge of
which devices are affected by the event.
• System Events - ACPI provides a general event mechanism that can be used for
system events such as thermal events, power management events, docking, device
insertion and removal, etc. This mechanism is very flexible in that it does not define
specifically how events are routed to the core logic chipset.
• Battery management - Battery management policy moves from the APM BIOS to the
ACPI OS. The OS determines the Low battery and battery warning points, and the
OS also calculates the battery remaining capacity and battery remaining life. An
ACPI-compatible battery device needs either a Smart Battery subsystem interface,
which is controlled by the OS directly through the embedded controller interface, or
a Control Method Battery (CMBatt) interface. A CMBatt interface is completely
defined by AML control methods, allowing an OEM to choose any type of the
battery and any kind of communication interface supported by ACPI.
• Thermal management - Since the OS controls the power states of devices and
processors, ACPI also addresses system thermal management. It provides a simple,
scaleable model that allows OEMs to define thermal zones, thermal indicators, and
methods for cooling thermal zones.
• Embedded Controller - ACPI defines a standard hardware and software
communications interface between an OS bus enumerator and an embedded
controller. This allows any OS to provide a standard bus enumerator that can directly
communicate with an embedded controller in the system, thus allowing other drivers
within the system to communicate with and use the resources of system embedded
controllers. This in turn enables the OEM to provide platform features that the OS
and applications can use.
• System Management Bus Controller - ACPI defines a standard hardware and
software communications interface between an OS bus driver and an SMBus
Controller. This allows any OS to provide a standard bus driver that can directly
communicate with SMBus Devices in the system. This in turn enables the OEM to
provide platform features that the OS and applications can use.
