Whenever a major component or device in your computer does not function properly, you may have a component failure. If you are experiencing a problem with your computer, Dell recommends that you perform the checks in "Solving Problems" and run the Dell Diagnostics before you call Dell for technical assistance.
As long as the microprocessor and the display, keyboard, and optical drive are working, you can use the Dell Diagnostics. Running the Dell Diagnostics may help you to resolve the problem yourself quickly without having to contact Dell for assistance.
If you are experienced with computers and know what component(s) you need to test, simply select the appropriate diagnostic test group(s) or subtest(s). If you are unsure about how to begin diagnosing a problem, see "Starting the Dell Diagnostics" and "Advanced Testing."
The Dell Diagnostics helps you check your computer's hardware without any additional equipment and without destroying any data. By using the diagnostics, you can have confidence in your computer's operation. And if you find a problem you cannot solve by yourself, the diagnostic tests can provide you with important information you will need when talking to Dell's service and support personnel. If you are experiencing a problem with your computer, Dell recommends that you perform the checks in "Solving Problems" and run the Dell Diagnostics before you call Dell for technical assistance.
NOTICE: Use the Dell Diagnostics to test only your Dell™ computer. Using
this program with other computers may cause incorrect computer responses or
result in error messages.
The diagnostic test groups or subtests also have these helpful features:
Options that let you perform quick checks or extensive tests on one or all devices
An option that allows you to choose the number of times a test group or subtest is repeated
The ability to display test results or to save them in a file
Options to temporarily suspend testing if an error is detected, or to terminate testing when an adjustable error limit is reached
Extensive online Help screens that describe the tests and how to run them
Status messages that inform you whether test groups or subtests were completed successfully
Error messages that appear if any problems are detected

For a quick check of your computer, select Quick Tests from the Test All Devices or Test One Device option. Quick Tests runs only the subtests that do not require user interaction and that do not take a long time to run. Dell recommends that you choose Quick Tests first to increase the odds of tracing the source of the problem quickly.
For a thorough check of your computer, select Extended Tests from the Test All Devices option.
To check a particular area of your computer, select Extended Tests from the Test One Device option, or select the Advanced Testing option to customize your test(s).
When you select Advanced Testing from the Diagnostics Menu, the Advanced Testing screen appears, listing the diagnostic test device groups and devices of the selected device group, and the screen allows you to select categories from a menu. Press the arrow keys or
to navigate the screen.
HINT: The test groups
reflect the configuration
of your computer.
Information in the Advanced Testing screen is presented as follows:
On the left side of the screen, the Device Groups area lists the diagnostic test groups in the order they will run if you select All from the Run tests menu category. Press the up- or down-arrow key to highlight a test device group.
On the right side of the screen, the Devices for Highlighted Group area lists the computer's currently detected hardware and some of the relevant settings.
Two lines at the bottom of the screen make up the menu area (see "Advanced Testing Help Menu"). The first line lists the categories you can select; press the left- or right-arrow key to highlight a menu category. The second line gives information about the category currently highlighted.
Provides descriptions of the main menu screen area, the device groups, the different diagnostic menus and commands, and instructions on how to use them.
Keys
Explains the functions of the all of the keystrokes that can be used in the Dell Diagnostics.
Device Group
Describes the test group that is presently highlighted in the Device Groups area on the main menu screen. It also provides reasoning for using some tests.
Device
Describes the function and purpose of the highlighted device in the DeviceGroups area. For example, the following information appears when you select the Device Help category for Diskette in the DeviceGroups list:
Diskette
Drive A
The diskette disk drive device reads and writes data to and from diskettes. Diskettes are flexible recording media, sometimes contained in hard shells. Diskette recording capacities are small and access times are slow relative to hard disk drives, but they provide a convenient means of storing and transferring data.
Test
Provides a thorough explanation of the test procedure of each highlighted test group subtest. An example of the Diskette subtest floppy drive Seek Test is as follows:
Diskette
Drive A - floppy drive Seek Test
This test verifies the drive's ability to position its read/write heads. The test operates in two passes: first, seeking from the beginning to ending cylinders inclusively, and second, seeking alternately from the beginning to ending cylinders with convergence towards the middle.
Versions
Lists the version numbers of the subtests that are used by the Dell Diagnostics.
When you boot your computer from your Drivers and Utilities CD, the diagnostics checks your system configuration information and displays it in the Device Groups area on the main screen.
The following sources supply this configuration information for the diagnostics:
The system configuration information settings (stored in NVRAM) that you selected while using the system setup program
Identification tests of the microprocessor, the video controller, the keyboard controller, and other key components
BIOS configuration information temporarily saved in RAM
Do not be concerned if the Device Groups area does not list the names of all the components or devices you know are part of your computer. For example, you may not see a printer listed, although you know one is attached to your computer. Instead, the printer is listed as a parallel port. The computer recognizes the parallel port as LPT1, which is an address that tells the computer where to send outgoing information and where to look for incoming information. Because your printer is a parallel communications device, the computer recognizes the printer by its LPT1 address and identifies it as a parallel port. You can test your printer connection in the Parallel Ports tests.
