Notes:
1. S4 implies operating system support only.
2. Wake from S4 and S5 is recommended by Microsoft.
3. Wake from device/event not supported immediately upon return from AC loss.
NOTE
Boards with AA# G81515-900 or higher support ErP Lot 6, Tier 2 requirements through
the 2-pin header at position J26. ErP Lot 6, Tier 2 support will disable all wake events
in the S4 sleep state (hibernate) and the S5 sleep state except for the power button.
The system will only wake from the S4 sleep state or the S5 sleep state with the power
button. Removing the jumper from the header at position J26 will disable ErP Lot 6,
Tier 2 support and will re-enable wake events.
NOTE
The use of these wake-up events from an ACPI state requires an operating system that
provides full ACPI support. In addition, software, drivers, and peripherals must fully
support ACPI wake events.
