Comments
If you select Enabled, the
Fn key works as the Ctrl
key, and the Ctrl key works
as the Fn key.
Note: Even when Enabled
is selected, you need to
press the Fn key to resume
the computer from sleep
mode to normal operation.
If you select Enabled, you
can press the Fn key once to
activate the Fn key function,
as if the key is kept in a
pressed condition, and then
press the desired function
key. The action is equivalent
to pressing the Fn key and
the desired function key
simultaneously. If you press
the Fn key twice, the Fn
key is kept in a pressed
condition until you press
the Fn key again.
Select the display device
that is to be activated at
boot time. This selection
is effective for boot time,
password prompt, and
ThinkPad Setup.
If you select Integrated
Graphics mode, it provides
longer battery life. If you
select NVIDIA Optimus
mode, it enhances the
graphics performance but it
reduces the battery life.
If you select Enabled, the
system UEFI automatically
switches the graphics
device setting to NVIDIA
Optimus mode if the
operating system supports
this feature, and to
integrated graphics mode if
the operating system does
not support this feature.
