Appendix
Using the System Setup Program
 NOTE: Your operating system may automatically configure most of the options available in the system setup 
program, thus overriding options that you set through the system setup program. (An exception is the External 
Hot Key option, which you can disable or enable only through the system setup program.) For more information 
on configuring features for your operating system, see the Windows Help and Support Center. To access the 
Help and Support Center, see page 13.
The system setup screens display the current setup information and settings for your computer, 
such as:
 System configuration
 Basic device-configuration settings
 System security and hard-drive password settings
 Power management settings
 Boot (start-up) configuration and display settings
 Docking-device settings
 Wireless control settings
 NOTICE: Unless you are an expert computer user or are directed to do so by Dell technical support, do not 
change the system setup program settings. Certain changes might make your computer work incorrectly. 
Viewing the System Setup Screen
1Turn on (or restart) your computer.
2When the DELL™ logo appears, press  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 Screen
The system setup screen consists of three windows of information. The window on the left contains 
an expandable hierarchy of control categories. If you select (highlight) a category (such as System, 
Onboard Devices, or Vi d e o) and press , you can show or hide the related subcategories. 
The window on the right contains information about the category or subcategory selected in the 
window on the left.  
						

							166Appendix
The window at the bottom tells you how to control the system setup program with key functions. Use 
these keys to select a category, modify its settings, or exit the system setup program.
Commonly Used Options
Certain options require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
The boot sequence, or boot order, 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 Order 
page of the system setup program.
 NOTE: To change the boot sequence on a one-time-only basis, see Performing a One-Time Boot on page 166.
The Boot Order page displays a general list of the bootable devices that may be installed in your 
computer, including but not limited to the following:
 Diskette Drive
 Internal HDD
 USB Storage Device
 CD/DVD/CD-RW drive
 Modular bay HDD
 NOTE: Only devices that are preceded by a number are bootable.
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 are preceded 
by a number; disabled items are not preceded by a number.
 To reorder a device in the list, highlight the device and press either  to move the device up the list 
or  to move a device down the list.
Boot sequence changes take effect as soon as you save the changes and exit the system setup program.
Performing a One-Time Boot
You can set a one-time-only boot sequence without entering the system setup program. (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.
2Connect the computer to an electrical outlet. 
						

							Appendix167
3Turn on the computer. When the DELL logo appears, press  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.
4When the boot device list appears, highlight the device from which you want to boot and press 
.
The computer boots to the selected device.
The next time you reboot the computer, the previous boot order is restored.
Cleaning Your Computer
 CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the 
Product Information Guide.
Computer, Keyboard, and Display
 CAUTION: Before you clean your computer, disconnect the computer from the electrical outlet and remove any 
installed batteries. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol 
cleaners, which may contain flammable substances.
 Use a can of compressed air to remove dust from between the keys on the keyboard and to remove any 
dirt or lint from the display.
 NOTICE: To help prevent damage to the computer or display, do not spray cleaning solution directly onto the 
display. Only use products specifically designed for cleaning displays, and follow the instructions that are included 
with the product.
 Moisten a soft, lint-free cloth with either water or a display cleaner. Do not use alcohol or an ammonia-
based cleaner. Wipe the display gently working from the center to the edges until it is clean and any 
fingerprints are removed. Do not use excessive pressure. 
 Moisten a soft, lint-free cloth with water and wipe the computer and keyboard. Do not allow water 
from the cloth to seep between the touch pad and the surrounding palm rest.
Touch Pad
1Shut down and turn off your computer. See Turning Off Your Computer on page 109. 
2Disconnect any attached devices from the computer and from their electrical outlets.
3Remove any installed batteries. See Using a Battery on page 37. 
4Moisten a soft, lint-free cloth with water, and wipe it gently across the surface of the touch pad. Do not 
allow water from the cloth to seep between the touch pad and the surrounding palm rest.  
						

							168Appendix
Floppy Drive
 NOTICE: Do not attempt to clean drive heads with a swab. You might accidentally misalign the heads which 
prevents the drive from operating.
Clean your floppy drive using a commercially available cleaning kit. These kits contain pretreated 
floppies to remove contaminants that accumulate during normal operation.
CDs and DVDs
 NOTICE: Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come 
with the compressed-air product. Never touch the lens in the drive.
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning 
the discs.
1
Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
 NOTICE: To help prevent damage to the surface, do not wipe in a circular motion around the disc.
2With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line 
from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase 
commercial products that clean discs and provide some protection from dust, fingerprints, and 
scratches. Cleaning products for CDs are also safe to use on DVDs.
