Power Management; Battery; Wake On Ring / Resume On Ring Technologies (Optional) - Intel BI440ZX Product Manual

Power Management

The motherboard supports two types of power management — Advanced Power Management
(APM) and Advanced Configuration and Power Interface (ACPI). If the board is used with an
ACPI-aware operating system, the BIOS provides ACPI support. Otherwise, it defaults to
APM support.

computer is turned off.

Wake on Ring / Resume on Ring Technologies (Optional)

The board supports two technologies that enable telephony devices (such as modems) to access the
computer when it is in a power-managed state. The method used depends on the type of telephony
device (external or internal) and the power management mode being used (APM or ACPI). The
optional Wake on Ring connector is used to implement this feature.
