Intel Desktop Board D915PCY/D915PCM Technical Product Specification
Resume on Ring enables telephony devices 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).
NOTE
The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an
operating system that provides full ACPI support.
1.13.2.1
Power Connector
ATX12V-compliant power supplies can turn off the system power through system control. When
an ACPI-enabled system receives the correct command, the power supply removes all non-standby
voltages.
When resuming from an AC power failure, the computer returns to the power state it was in before
power was interrupted (on or off). The computer's response can be set using the Last Power State
feature in the BIOS Setup program's Boot menu.
