Table 5-3 Computer Setup-Advanced (for advanced users) (continued) ● Front USB ports ● Rear USB ports ● Media card reader Restrict USB Devices Specify the following categories of USB devices to enable: ● Allow all USB devices ● Allow only keyboard and mouse ● Allow all but storage devices and hubs. Option ROM Launch Policy These policies control whether the Legacy Option ROM or the UEFI driver is loaded. Default is 'All UEFI'. Configure Option ROM Launch Policy ● All legacy ● All UEFI ● All UEFI except video Power Management Options Runtime Power Management (enable/disable) Allows certain operating systems to reduce processor voltage and frequency when the current software load does not require the full capabilities of the processor. Default is enabled. Extended Idle Power States (enable/disable) Allows certain operating systems to decrease the processors power consumption when the processor is idle. Default is enabled. S5 Maximum Power Savings (enable/disable) Enabling this feature reduces the power of the system as much as possible in the S5 state. Power is removed from the wake up circuitry, the expansion slots, and any management features while in S5. Default is disabled. SATA Power Management (enable/disable) Enables or disables SATA bus and/or device power management. Default is enabled. PCI Express Power Management (enable/disable) Enabling this option permits the PCI Express links to use Active Power State Management (ASPM) to enter lower power states while not in use. Default is enabled. Unique Sleep State Blink Rates (enable/disable) This feature is designed to provide a visual indication of what sleep state the system is in. Each sleep state has a unique blink pattern. Default is disabled. NOTE: A normal shutdown goes to the S4 state. S0 (On) = Solid white LED. S3 (Stand By)= 3 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (white LED) - repeated cycles of 3 blinks and a pause. S4 (Hibernation)= 4 blinks at 1Hz (50% duty cycle) followed by a pause of 2 seconds (white LED) - repeated cycles of 4 blinks and a pause. S5 (Soft Off) = LED is off. Power On from Keyboard Ports (enable/disable) Enables or disables waking from S3 due to any keyboard activity. Default is disabled.
