Desktop Board Features

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.

The desktop board’s standby power indicator, shown in Figure 4, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off.

If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

•Resumes operation from either ACPI S1 or ACPI S3 state

•Requires only one call to access the computer

•Detects incoming call similarly for external and internal modems

•Requires modem interrupt be unmasked for correct operation
