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:
l
COM1
(the default)
—
Maps the serial port to COM1
l
COM2
—
Maps the serial port to COM2
l
COM3
—
Maps the serial port to COM3
l
COM4
—
Maps the serial port to COM4
l
Disabled
—
Disables the serial port and its assigned COM address, freeing that interrupt for another 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 service code, which was programmed into nonvolatile random-access memory (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 support software, including diagnostics. No user-
selectable settings are available for this option.
Smart CPU Mode
Smart CPU Mode
allows the computer to slow down the microprocessor automatically if it is not being actively used. This feature is a key
component to the thermal control of the system.
Settings for this option are:
l
Enabled
(the default) —
Saves power, helps to lower system temperatures, and extends battery life by allowing the computer to slow down
the microprocessor when it is inactive
l
Disabled
—
Keeps the microprocessor running at its normal operating speed regardless of microprocessor inactivity
A change to the
Smart CPU Mode
option takes effect immediately (rebooting is not required).
Suspend Time-out
Suspend Time-out
lets you determine how long your computer remains idle before activating standby mode to conserve battery power.
Settings for this option in both
AC
and
Battery
categories are:
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). 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.
NOTE: With systems running under ACPI, power management settings are controlled from the
Power Management Properties
window
in the
Control Panel
. Certain features require configuration through the
Power Management Properties
window and others may not
function with ACPI.
NOTES: In rare situations, some communications software may not work properly when
Smart CPU Mode
is enabled. Dell
recommends that you set
Smart CPU Mode
to
Disabled
if your computer is experiencing performance degradation.
Interactive application programs should function well when
Smart CPU Mode
is set to
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
.
NOTE: With systems running under ACPI, power management settings are controlled from the
Power Management Properties
window
in the
Control Panel
. Certain features require configuration through the
Power Management Properties
window and others may not
function with ACPI.
