Product Description its last known wake state. Table 12 on page 34 lists the devices and events that can wake the computer from the S3 state. 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 Express add-in cards and drivers. 1.11.2.5 Wake from USB USB bus activity wakes the computer from an ACPI S3 state. NOTE Wake from USB requires the use of a USB peripheral that supports Wake from USB. 1.11.2.6 WAKE# Signal Wake-up Support When the WAKE# signal on the PCI Express bus is asserted, the computer wakes from an ACPI S3, S4, or S5 state. 1.11.2.7 Wake from Consumer IR CIR activity wakes the computer from an ACPI S3, S4, or S5 state. 1.11.2.8 Wake from S5 When the RTC Date and Time is set in the BIOS, the computer will automatically wake from an ACPI S5 state. 1.11.2.9 Power Supervisor The Power Supervisor actively monitors the input voltages from the power supply and protects the board and any attached peripherals from electrical overstress and possible physical damage. The Power Supervisor will activate if it detects the power supply voltage rails have deviated outside the current ATX power supply specification and safe operating levels. If the Power Supervisor detects an out of spec voltage, the following will happen: 1. The board will be powered down immediately to protect circuits from electrical overstress and possible physical damage. 2. A red warning LED (see Figure 1) on the board will activate as a visual cue. 3. During the next power on, a message will be displayed on the screen to notify the user that the power supply voltage rails have deviated outside the current ATX power supply specification and safe operating levels. 4. A message will be added to the BIOS Event Log for each event that takes place until the BIOS Event Log is cleared. 37
