Customizing System Features 2-11
A change to the S2D TIME-OUT option takes effect immedi-
ately (rebooting is not required).
If you are not in the System Setup program, you can acti-
vate suspend-to-disk mode at any time by pressing
<
FN >< A >. Press the power switch to resume from suspend-to-
disk mode.
Serial Port
SERIAL PORT allows you to map the address of the serial
port or to disable the serial port.
Settings for this option are:
•
COM1 (the default) maps the serial port to COM1.
•
COM2 maps the serial port to COM2.
•
COM3 maps the serial port to COM3
•
COM4 maps the serial port to COM4.
•
DISABLE disables the serial port and its assigned
COM address freeing its interrupt for another serial
device to use.
For a change in the SERIAL PORT option to take effect, you
must reboot your computer.
Service Tag
SERVICE TAG displays the computer’s five-character ser-
vice code, which was programmed into NVRAM by Dell
during the manufacturing process. Be prepared to supply
this identification during technical assistance or service
calls. The service tag is also accessed by certain Dell sup-
port software, including diagnostics.
There are no user-selectable settings for this option.
NOTE: Convert the service tag number into an express
service code when prompted to do so the first time you
turn on the computer (or use the program in the Dell
Accessories folder or program group). Keep the code
handy in case you call Dell for technical assistance. The
code helps Dell’s automated support telephone system
direct your call more efficiently.
Smart CPU Mode
SMART CPU MODE allows the computer to slow down the
microprocessor automatically if it is not being actively
used.
Settings for this option are:
•
ENABLED (the default) allows the computer to slow
down the microprocessor when it is inactive.
•
DISABLED keeps the microprocessor running at its
normal operating speed regardless of microprocessor
inactivity.
To increase battery operating time, set the SMART CPU
MODE option to ENABLED .
When the SMART CPU MODE option is enabled and the micro-
processor is inactive, the computer slows the microprocessor to
save power.
NOTES: Some communications software may not work
properly when
SMART CPU MODE is enabled. Dell
recommends that you set SMART CPU MODE to DISABLED if
you are using communications software.
Interactive application programs should function well
when
SMART CPU MODE is enabled. (Examples of interactive
programs include spreadsheet, text editor, graphics design,
entertainment, educational, and utility programs.) However, you
may experience performance degradation when recalculating a
large spreadsheet or during an extensive screen redraw in a
graphical program. Benchmark utilities may not perform as
intended when doing microprocessor speed tests. If the software
you use suffers significant performance degradation, set
SMART
CPU MODE to DISABLED .
A change to the SMART CPU MODE option takes effect
immediately (rebooting is not required).
Speaker Volume
SPEAKER VOLUME allows you to disable or adjust the
volume of the computer’s built-in speakers or attached
external speakers.The settings for this option are
HIGH
(the default), MEDIUM , LOW , and DISABLED . To preview a
volume setting, press the right- or left-arrow key several
times while this option is highlighted and listen to the beep.
NOTE: Warning sounds, such as low-battery beeps, will
sound even if
SPEAKER VOLUME is set to DISABLED .
A change to the SPEAKER VOLUME option takes effect
immediately (rebooting is not required).
