• Power Management: This option allows you to select the type (or
degree) of power saving for Doze, Standby, and Suspend modes. This
table describes the power management modes for your reference:
• HDD Power Down: When enabled and after the set time of system
inactivity, the hard disk drive will be powered down while all other
devices remain active.
• Suspend Mode: After the selected period of system inactivity, the
chipset enters a hardware suspend mode, stopping the CPU clock and
possibly causing other system devices to enter power management
modes.
• Doze Mode: After the selected period of system inactivity, the CPU
clock runs at slower speed while all other devices still operate at full
speed.
