Overview
Viewing the System Setup Screens
System Setup Screens
Commonly Used Settings
Overview
NOTE: Your operating system may automatically configure most of the options available in
system setup, thus overriding options that you set through system setup. (An exception is the
External Hot Key option, which you can disable or enable only through system setup.) For
more information on configuring features for your operating system, see the Help and Support
Center. See
Windows Help and Support Center.
You can use system setup as follows:
● To set or change user-selectable featuresfor example, your computer password
● To verify information about the computer's current configuration, such as the amount of system
memory
After you set up the computer, run system setup to familiarize yourself with your system configuration
information and optional settings. You may want to write down the information for future reference.
The system setup screens display the current setup information and settings for your computer, such
as:
● System configuration
● Boot order
● Boot (start-up) configuration and docking-device configuration settings
● Basic device-configuration settings
● System security and hard-drive password settings
file:///S|/Integration%20Specialist/Hardware%20Docu...ation/Kim%20&%20Jay/Dell%20Laptops/D620UG/setup.htm (1 of 4) [12/4/2008 10:53:59 AM]
System Setup Program: Dell Latitude D620 User's Guide
NOTICE: Unless you are an expert computer user or are directed to do so by Dell technical
support, do not change the system setup settings. Certain changes might make your computer
work incorrectly.
Viewing the System Setup Screens
1. Turn on (or restart) your computer.
2. When the DELL logo appears, press <F2> immediately. If you wait too long and the Windows
logo appears, continue to wait until you see the Windows desktop. Then shut down your
computer and try again.
System Setup Screens
In System Setup, primary categories of settings are listed on the left. To view the types of settings in a
category, highlight the category and press <Enter>. When you highlight a setting type, the right side
of the screen displays the value for that setting type. You can change settings that appear as white
type on the screen. Values that you cannot change (because they are determined by the computer)
appear less bright.
System-setup key functions are listed across the bottom of the screen.
Commonly Used Settings
Certain settings require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
The boot sequence tells the computer where to look to find the software needed to start the operating
system. You can control the boot sequence and enable/disable devices using the Boot Sequence
page, which is located in the System category.
NOTE: To change the boot sequence on a one-time-only basis, see Performing a One-Time Boot.
The Boot Sequence page displays a general list of the bootable devices that may be installed in your
computer, including but not limited to the following:
file:///S|/Integration%20Specialist/Hardware%20Docu...ation/Kim%20&%20Jay/Dell%20Laptops/D620UG/setup.htm (2 of 4) [12/4/2008 10:53:59 AM]
System Setup Program: Dell Latitude D620 User's Guide
● Diskette Drive
● Modular bay HDD
● Internal HDD
● CD/DVD/CD-RW drive
During the boot routine, the computer starts at the top of the list and scans each enabled device for
the operating system start-up files. When the computer finds the files, it stops searching and starts the
operating system.
To control the boot devices, select (highlight) a device by pressing the down-arrow or up-arrow key,
and then enable or disable the device or change its order in the list.
● To enable or disable a device, highlight the item and press the space bar. Enabled items appear
as white and display a small triangle to the left; disabled items appear blue or dimmed without
a triangle.
● To reorder a device in the list, highlight the device and then press <u> or <d> (not case-
sensitive) to move the highlighted device up or down.
Boot sequence changes take effect as soon as you save the changes and exit system setup.
Performing a One-Time Boot
You can set a one-time-only boot sequence without entering system setup. (You can also use this
procedure to boot the Dell Diagnostics on the diagnostics utility partition on your hard drive.)
1. Shut down the computer through the Start menu.
2. If the computer is connected to a docking device (docked), undock it. See the documentation
that came with your docking device for instructions.
3. Connect the computer to an electrical outlet.
4. Turn on the computer. When the DELL logo appears, press <F12> immediately. If you wait too
long and the Windows logo appears, continue to wait until you see the Windows desktop. Then
shut down your computer and try again.
5. When the boot device list appears, highlight the device from which you want to boot and press
<Enter>.
The computer boots to the selected device.
The next time you reboot the computer, the previous boot order is restored.
Changing COM Ports

Serial Port, which is located in the Onboard Devices category, allows you to map the serial port
COM address or disable the serial port and its address, which frees computer resources for another
device to use.
Enabling the Infrared Sensor
1. Locate Fast IR under Onboard Devices.
NOTE: Ensure that the COM port that you select is different from the COM port assigned to the
serial connector.
2. Press <Enter>.
3. Use the arrow keys to select the infrared COM port setting.
4. Press <Enter>.
5. Follow the instructions on the screen.
After you enable the infrared sensor, you can use it to establish a link to an infrared device. To set up
and use an infrared device, see the infrared device documentation and the Windows XP Help and
Support Center (see
Windows Help and Support Center).

Drivers
What Is a Driver?
A driver is a program that controls a device such as a printer, mouse, or keyboard. All devices require
a driver program.
A driver acts like a translator between the device and any other programs that use the device. Each
device has its own set of specialized commands that only its driver recognizes.
Dell ships your computer to you with required drivers already installedno further installation or
configuration is needed.

Search Criteria, select the appropriate categories from the System Model, Operating
System, and Topic drop-down menus.
