Comments
If you select Enabled, the
system UEFI automatically
switches the graphics
device setting to Switchable
Graphics mode if the
operating system supports
this feature, and to
Integrated Graphics mode if
the operating system does
not support this feature.
Select the mode of Intel
SpeedStep technology at
runtime.
• Maximum
Performance: Always
highest speed
• Battery Optimized:
Always lowest speed
• Disabled: No runtime
support, lowest speed
Note: This sub-menu is not
supported in models with
an AMD CPU.
Unless this power-saving
feature is disabled, it
stops the processor clock
automatically when there
is no system activity. You
usually do not need to
change this function.
Note: To use this feature, a
special partition on the M.2
solid-state drive is required.
When enabled, the system
enters a lower power state
after the specified time in
sleep state. And it takes
only seconds to resume
normal operation.
