Service manual

Using the System Setup Program: Dell Latitude CP
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 service 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
support 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). 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 - 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
The default for Smart CPU Mode is Enabled if the computer is operating on battery power. If
the computer is using AC power, the default for this option is Disabled. To increase battery
operating time, set the Smart CPU Mode option to Enabled.
When the Smart CPU Mode option is enabled and the microprocessor 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.
