Option Heading
Lets you disable the ports. Default is enabled.
Right USB ports
Lets you disable the ports. Default is enabled.
USB Legacy Port Charging
Lets you enable USB charging port capability when the computer is in hibernate or shutdown mode.
Default is enabled.
USB Type-C Downstream Charging
Lets you enable USB charging port capability when the computer is in hibernate on or o. Default is
enabled.
Restrict USB Devices
Specify the following categories of USB devices to enable:
● Allow all USB devices (default)
● Allow only keyboard and mouse
● Allow all but storage devices and hubs.
When some devices are restricted, the system will disable USB ports that do not meet the allowed
criteria. This feature is usually combined with similar policies within the operating system because USB
devices can be moved to dierent ports. The ports disabled by the BIOS remain disabled until the system
is restarted.
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, device power management, or both. 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
l
ower power states while not in use. Default is enabled.
Power On from Keyboard Ports (enable/disable)
When enabled, this feature allows a key press to turn on the system when it is o (S5 state). If using a USB
keyboard, you must plug it into one of the rear ports labeled with the keyboard icon. Default is disabled.
Unique Sleep State Blink Rates (enable/disable)
