Dell Latitude CP Reference and Troubleshooting Guide
Display Close
Display Close lets you determine whether your computer
enters suspend mode when the display is closed, or
whether only the display is turned off.
Settings for this option are:
•
Suspend (the default) — Allows the computer to
enter suspend mode when the display is closed
•
Active — Turns off the display, but does not put the
computer into suspend mode
Display Time-Out
Display Time-Out lets you decide how long the computer
operates with no input/output (I/O) activity before turn-
ing off the display to conserve battery power.
Settings for this option in both the AC and Battery cate-
gories are:
The default setting is 4 Minutes. To increase battery oper-
ating time, set Display Time-Out to a lower number of
minutes.
NOTE: Set the Display Time-Out option to Disabled if
using it causes compatibility problems with your
software.
A change to the Display Time-Out option takes effect
immediately (rebooting is not required).
If you are not in the System Setup program, you can turn
off the display immediately by pressing <Fn><d>. The
display resumes normal operation automatically when
you press a key, move the cursor, or press the power
button.
Docking Status
Docking Status shows whether the computer is attached
to the Dell Latitude C/Port Advanced Port Replicator
(APR) or C/Dock Expansion Station. There are no user-
selectable settings for the Docking Status option.
External Cache
External Cache
tells you how much external cache your
computer has. There are no user-selectable settings for
the External Cache option.
External Hot Key
External Hot Key
lets you use the <Scroll Lock> key on
an external keyboard the same way you use the <Fn> key
on the computer’s built-in keyboard. Set this option to
Scroll Lock (the default) if you are using an external key-
board. Set this option to Not Installed to disable this
function on the external keyboard.
Infrared Data Port
Infrared Data Port allows you to avoid resource conflicts
by remapping the address of the infrared port or disabling
the port. The COM1, COM2, COM3, and COM4 settings
allow you to take advantage of the computers’s Fast IR
support.
Settings for this option are:
•
Disabled — Disables the infrared data port and
makes the DMA, IRQ, and I/O resources available
for another serial device to use
•
COM1 — Maps the infrared data port to COM1
•
COM2 — Maps the infrared data port to COM2
•
COM3 (the default) — Maps the infrared data port to
COM3
•
COM4 — Maps the infrared data port to COM4
For a change in the Infrared Data
Port option to take
effect, you must reboot your computer.
Infrared Mode
The Infrared Mode option appears on the screen only
after an address is assigned in the Infrared Data Port
option. Infrared Mode lets you select Fast IR mode or
Slow IR mode for use with an infrared device. Select
Slow IR if the Parallel Mode option is set to ECP and the
Audio Mode option is set to Full Duplex.
NOTES: The System Setup program limits the options
available for Infrared Mode, depending on how the Par-
allel Mode and Audio Mode options are set. If Parallel
Mode is set to ECP and Audio Mode is set to Full
