Resume On Ring; Wake From Usb; Wake From Ps/2 Keyboard/Mouse; Pme# Wakeup Support - Intel D865PCK Product Manual

Intel Desktop Board D865PCK Product Guide
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep
state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up
device or event, the system quickly returns to its last known awake state.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber.
