Customizing System Features 2-11A 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 PortSERIAL PORT allows you to map the address of the serialport 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 assignedCOM address freeing its interrupt for another serialdevice to use.For a change in the SERIAL PORT option to take effect, youmust reboot your computer.Service TagSERVICE TAG displays the computer’s five-character ser-vice code, which was programmed into NVRAM by Dellduring the manufacturing process. Be prepared to supplythis identification during technical assistance or servicecalls. 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 expressservice code when prompted to do so the first time youturn on the computer (or use the program in the DellAccessories folder or program group).
