9.1 Supported ACPI States

Advanced Configuration and Power Interface (ACPI) is a standard interface for enabling the operating
system to direct configuration and power management. The PowerEdge T310 BIOS is compliant with
ACPI version 2.0a.

9.2 BIOS Power Management

Power management features come in two flavors: fixed or generic.
Fixed features use bits defined in the ACPI specification for specific capabilities. The fixed feature
bits give the OS complete control over the power management of a device since the location of the
bits is given to the OS in the FACP table. Thus, a driver can directly access bits to control a device's
power management.
Generic features have defined enable and status bits, but the functionality is not fully visible to the
OS. Dell provides ASL code to handle the details of generic features, allowing the OS to intelligently
communicate with system-specific hardware.
Table 15 summarizes the power management features on this system.
