Intel Desktop Board D915GVWB Technical Product Specification
36
The board supports the
PCI Bus Power Management Interface Specification
.
Add-in boards that
also support this specification can participate in power management and can be used to wake the
computer.
The use of Instantly Available PC technology requires operating system support and PCI 2.2
compliant add-in cards, PCI Express add-in cards, and drivers.
1.12.2.5
Resume on Ring
The operation of Resume on Ring can be summarized as follows:
•
Resumes operation from ACPI S1 or S3 states
•
Detects incoming call similarly for external and internal modems
•
Requires modem interrupt be unmasked for correct operation
1.12.2.6
Wake from USB
USB bus activity wakes the computer from ACPI S1 or S3 states.
±
NOTE
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
1.12.2.7
Wake from PS/2 Devices
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
1.12.2.8
PME# Signal Wake-up Support
When the PME# signal on the PCI Conventional bus is asserted, the computer wakes from an ACPI
S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).
1.12.2.9
WAKE# Signal Wake-up Support
When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI
S1, S3, S4, or S5 state.
1.12.2.10
+5 V Standby Power Indicator LED
The +5 V standby power indicator LED shows that power is still present even when the computer
appears to be off.
Figure 13 shows the location of the standby power indicator LED.
CAUTION
If AC power has been switched off and the standby power indicator is still lit, disconnect the power
cord before installing or removing any devices connected to the board.
Failure to do so could
damage the board and any attached devices.
