PS/2 Device submenu
The PS/2 Device submenu allows you to enable or
disable the “hot-pluggability” of PS/2 devices. It also
allows you to determine the conditions under which the
internal PS/2 port is enabled.
Figure 14. PS/2 Device submenu
The PS/2 Device submenu consists of a Hotplug
checkbox (enabled by default) and an Internal Pointing
Device section.
When Hotplug is checked, PS/2 devices can be plugged
in -- and will be recognized -- while the system is
running. When Always Disable or Manual
Setting are selected in the Internal Pointing Device
section, the Hotplug selection cannot be selected.
The Internal Pointing Device section consists of four
selections:
■
Always Enable
When selected, the internal pointing device (touchpad)
is enabled whether or not a PS/2 device is attached.
■
Always Disable
When selected, the internal pointing device (touchpad)
is never enabled.
■
Auto Disable
When selected, the internal pointing device (touchpad)
is disabled automatically when a PS/2 device is attached.
■
Manual Setting
When selected, the internal pointing device (touchpad)
operation is determined by desktop selection.
LID submenu
The LID submenu allows you to determine what action
the system takes when the lid is opened and closed.
Figure 15. LID submenu
There are two selections on the LID submenu:
■
Lid Closure Suspend:
This is enabled by default. When it is enabled, the system
will go into Suspend mode automatically when the lid is
closed. When it is disabled (unchecked), the system will
continue to run when the lid is closed.
■
Lid Open Resume:
This is enabled by default. When it is enabled, the system
will automatically resume operation when the lid is
opened. When it is disabled (unchecked), the system
requires user intervention in order to resume (by
pressing the On/Off button).
Keyboard Numlock submenu
The Keyboard Numlock submenu allows you to deter-
mine the state of the system’s numerical keypad.
Figure 16. Keyboard Numlock submenu
The Keyboard Numlock submenu offers three choices:
Off, On, and Auto. Auto is the default selection.
When Off or On are selected, the numerical keypads are
disabled or enabled, respectively. When Auto is
selected, the state of the numerical keypads is deter-
mined by the system.
