Index of Symptoms, Messages, Error Codes, or
Beeps
Table 2-1 on page 2-11 lists failure symptoms and possible causes. The
most likely cause is listed first. Make sure you complete all items in the
cause or “Action/FRU” column. When servicing a system, always begin with
“Start” on page 2-2. This index can also be used to help you decide which
FRUs to have available when servicing a system.
If you are unable to correct the problem using this index, go to
“Undetermined Problem” on page 2-56.
Notes:
1. If an error message and incorrect audio response occur, diagnose the
error message first.
2. If you cannot run the Diagnostics and Utilities tests but did receive a
POST error code, diagnose the POST error message.
3. If you did not receive any error message, look for a description of your
error symptoms in the first part of this index.
4. Check all power supply voltages, switch, and jumper settings before you
replace the system board. Also check the power supply voltages if you
have a system no-power condition. (See “Power Supply” on page 2-34,
“System Board Layout—Type A-1” on page 5-2, and “System Board
Layout—Type A-2” on page 5-5)
5. Certain models come with a DVD-ROM drive instead of a CD-ROM
drive. Diagnose the DVD-ROM drive models the same as the CD-ROM
drive models.
6. Type 2142 comes with the Media Console which controls the keyboard,
mouse, diskette drive and CD/DVD-ROM drive. Diagnose the Media
Console first, before replacing the system board for problems with the
keyboard, mouse, diskette, or CD/DVD-ROM drive. Depending on
service procedures, replace either the Media Console FRU items or the
Media Console.
In Table 2-1 on page 2-11, an X in an error code can be any number. If
you are unable to correct the problem using this index, go to “Undetermined
Problem” on page 2-56.
