Comments
Integrated Graphics
provides longer battery life,
and Switchable Graphics
enhances performance.
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.
Enable or disable the power
saving feature that stop
the microprocessor clock
automatically when there
are no system activities.
Normally, it is not necessary
to change the setting.
If this function is enabled,
a beep sounds when the
computer enters a power
management mode, when it
resumes operational mode,
and when the ac power
adapter is connected or
disconnected.
Enable or disable the low
battery alarm.
Enable this option to have
a beep sound when the
system is waiting for a
power-on, hard disk, or
supervisor password.
Different beeps will be
sounded when the entered
password matches or does
not match the configured
password.
Enable or disable keyboard
beep when unmanageable
key combinations are
pressed.
