Overview

This section provides troubleshooting procedures for equipment that connects directly to the input/output (I/O) panel of your computer, such as your
monitor, keyboard, mouse, or printer. Before performing any of the procedures in this section, see "

Checking Connections and Switches

." Then

perform the troubleshooting procedures for the equipment that is malfunctioning.

You need a copy of the

Dell ResourceCD

to perform the procedures in this section.

Before running the

Dell Diagnostics

, make sure that your system is set to boot from the CD-ROM drive. See "

Starting the Dell Diagnostics

" for

complete instructions.

Troubleshooting the Monitor

Troubleshooting video problems involves determining which of the following is the source of the problem:

l

Monitor or monitor interface cable

l

Video controller

The procedures in this section troubleshoot problems with the monitor and the monitor interface cable only.

If information on the monitor screen is displayed incorrectly or not at all, perform each of the following steps in the order indicated until the problem
is resolved:

1. Turn on the system, including any attached peripherals.

2. Adjust the switches and controls as specified in the monitor's documentation to correct the video image, including the horizontal and vertical

position and size.

3. Start the

Dell Diagnostics

by inserting the

Dell ResourceCD

and rebooting the system.

4. Run the

Video

test group.

5. Turn off the system and disconnect it from the electrical outlet. Swap the monitor with one of the same type that is working, and reconnect the

system to an electrical outlet.

6. Reboot the system, and run the

Video

test group again.

7. If the tests complete successfully, the original monitor was faulty. If the tests still fail, the video controller on the system board may be faulty.

See "

Getting Help

" for instructions on obtaining technical assistance.

Troubleshooting the Keyboard

This procedure determines what kind of keyboard problem you have. If a system error message indicates a keyboard problem when you start the
computer system or if the keyboard does not operate as expected, perform the following steps in the order indicated until the problem is resolved:

1. If the keyboard or its cable shows signs of physical damage or if the keys do not work, replace the keyboard with a working keyboard.

2. Start the

Dell Diagnostics

by inserting the

Dell ResourceCD

and rebooting the system.

3. Run the

Keyboard

test group.

4. If the

Keyboard Interactive Test

fails, replace the keyboard.

5. If the

Keyboard Controller Test

fails, the system board may be faulty. See "

Getting Help

" for instructions on obtaining technical assistance.
