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 installed—no
further installation or configuration is needed.
NOTICE: Your Drivers and Utilities media may contain drivers for operating systems
that are not on your computer. Ensure that you are installing software appropriate
for your operating system.
Many drivers, such as the keyboard driver, come with your Microsoft®
Windows® operating system. You may need to install drivers if you:
• Upgrade your operating system.
• Reinstall your operating system.
• Connect or install a new device.
Identifying Drivers
If you experience a problem with any device, identify whether the driver is the
source of your problem and, if necessary, update the driver.
1
Click
Start
, and then right-click
Computer
.
2
Click
Properties
, and then click
Device Manager
.
NOTE: The User Account Control window may appear. If you are an
administrator on the computer, click Continue; otherwise, contact your
administrator to continue.
Scroll down the list of devices and check for an exclamation point (a circle with
a [
!]
) next to the device name
. If an exclamation point is next to the device
name, you may need to reinstall the driver or install a new driver (see
"Reinstalling Drivers and Utilities" on page 120).
120 Troubleshooting
Reinstalling Drivers and Utilities
NOTICE: The Dell Support website at support.dell.com and your Drivers and
Utilities media provide approved drivers for Dell computers. If you install drivers
obtained from other sources, your computer might not work correctly.
Using Windows Device Driver Rollback
If a problem occurs on your computer after you install or update a driver, use
Windows Device Driver Rollback to replace the driver with the previously
installed version.

computer to the operating state that existed before you installed the new
driver.
Using the Drivers and Utilities Media
If using Device Driver Rollback or System Restore (see "Restoring Your
Operating System" on page 122) does not resolve the problem, reinstall the
driver from your Drivers and Utilities media.

Restoring Your Operating System
You can restore your operating system in the following ways:
• Windows Vista System Restore returns your computer to an earlier
operating state without affecting data files. Use System Restore as the first
solution for restoring your operating system and preserving data files. For
instructions, see "Using Microsoft Windows System Restore" on page 123.
• If you received
Operating System
media with your computer, you can use it
to restore your operating system. However, using the
Operating System
media also deletes all data on the hard drive. Use the media
only
if System
Restore did not resolve your operating system problem. For instructions,
see "Using the Operating System Media" on page 123.
Troubleshooting 123
Using Microsoft Windows System Restore
The Windows operating system provides System Restore to allow you to
return your computer to an earlier operating state (without affecting data files)
if changes to the hardware, software, or other system settings have left the
computer in an undesirable operating state. Any changes that System Restore
makes to your computer are completely reversible.
NOTICE: Make regular backups of your data files. System Restore does not
monitor your data files or recover them.
NOTE: The procedures in this document were written for the Windows default view,
so they may not apply if you set your Dell computer to the Windows Classic view.

Rollback (see "Using Windows Device Driver Rollback" on page 120).
If Device Driver Rollback does not resolve the problem, then use System
124 Troubleshooting
Restore to return your operating system to the operating state it was in before
you installed the new device driver (see "Using Microsoft Windows System
Restore" on page 123).
NOTICE: Before performing the installation, back up all data files on your primary
hard drive. For conventional hard drive configurations, the primary hard drive is the
first drive detected by the computer.
Troubleshooting 125

NOTE: Your Drivers and Utilities media contains drivers that were installed during
assembly of the computer. Use your Drivers and Utilities media to load any required
drivers, including the drivers required if your computer has a RAID controller.
Reinstalling Windows
The reinstallation process can take 1 to 2 hours to complete. After you
reinstall the operating system, you must also reinstall the device drivers, virus
protection program, and other software.
NOTICE: The Operating System media provides options for reinstalling Windows.

least 8 to 10 seconds until the computer turns off.
128 Adding and Replacing Parts
Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from
potential damage and to help ensure your own personal safety.
CAUTION: Before you begin any of the procedures in this section, follow the
safety instructions in the Product Information Guide.
CAUTION: Handle components and cards with care. Do not touch the components
or contacts on a card. Hold a card by its edges or by its metal mounting bracket.
Hold a component such as a processor by its edges, not by its pins.
NOTICE: Only a certified service technician should perform repairs on your
computer. Damage due to servicing that is not authorized by Dell is not covered by
your warranty.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief
loop, not on the cable itself. Some cables have a connector with locking tabs; if you
are disconnecting this type of cable, press in on the locking tabs before you
disconnect the cable. As you pull connectors apart, keep them evenly aligned to
avoid bending any connector pins. Also, before you connect a cable, ensure that
both connectors are correctly oriented and aligned.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist
grounding strap or by periodically touching an unpainted metal surface (such as a
connector on the back of the computer).
1
Ensure that the work surface is flat and clean to prevent the computer
cover from being scratched.
2
Turn off your computer (see "Turning Off Your Computer" on page 127).
NOTICE: To disconnect a network cable, first unplug the cable from your
computer, and then unplug it from the network wall jack.
3
Disconnect any telephone or network cables from the computer.
4
Disconnect your computer and all attached devices from their electrical
outlets.
NOTICE: To help prevent damage to the system board, you must remove the
battery from the battery bay before you service the computer.
NOTE: To avoid damage to the computer, use only the battery designed for this
particular Dell computer. Do not use batteries designed for other Dell computers.
5
Turn the computer over.

Hard Drive
CAUTION: If you remove the hard drive from the computer when the drive is hot,
do not touch the metal housing of the hard drive.
CAUTION: Before you begin any of the procedures in this section, follow the
safety instructions in the Product Information Guide.
NOTICE: To prevent data loss, turn off your computer (see "Turning Off Your
Computer" on page 127) before removing the hard drive. Do not remove the hard
drive while the computer is on or in Sleep state.
NOTICE: Hard drives are extremely fragile. Exercise care when handling the
hard drive.
NOTE: Dell does not guarantee compatibility or provide support for hard drives
from sources other than Dell.
NOTE: If you are installing a hard drive from a source other than Dell, you need to
install an operating system, drivers, and utilities on the new hard drive (see
