Management
●
ACPI S3 Hard Disk Reset—Enabling this causes the BIOS to ensure hard disks are ready to
accept commands after resuming from S3 before returning control to the operating system.
●
ACPI S3 PS2 Mouse Wakeup—Enables or disables waking from S3 due to PS2 mouse activity.
●
USB Wake on Device Insertion (some models)—Allows system to wake from Standby on USB
device insertion.
●
Unique Sleep Blink Rates—This feature is designed to give the user a visual indication of the
sleep state the system is in. Each sleep state has a unique blink pattern:
◦
S0 = Solid green LED.
◦
S3 = 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED), i.e.,
repeated cycles of 3 blinks and a pause.
◦
S4 = 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (green LED), i.e.,
repeated cycles of 4 blinks and a pause.
◦
S5 = LED is off.
If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer supported) and S3
use 1 blink per second.
