Computer Setup-Power NOTE: Support for specific Computer Setup options may vary depending on the hardware configuration. Table 5 Computer Setup-Power Option Description OS Power 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. Hardware Power Management (some models) Thermal If this feature is disabled, S4 and S5 both have the LED off. S1 (no longer supported) and S3 use 1 blink per second. SATA power management enables or disables SATA bus and/or device power management. ● Fan idle mode-This bar graph controls the minimum permitted fan speed. NOTE: This setting only changes the minimum fan speed. The fans are still automatically controlled. 10 Computer Setup (F10) Utility ENWW
