This book comes with a diagnostic program diskette.
This diskette should be used ONLY with
Service Level A (SL-A)
Do not use thi s disket t e on other models.
POST error codes and error messages are displayed
on the screen after the IBM logo. Meanwhile, error
beeps could be issued to help diagnose syste

The hard disk dri ve c on t ain s pre-loaded so f t w are. Be
sure to reload the software on the primary hard disk
drive (Drive C) when replacing it.
IMPORTANT: The drives in the sys tem you are
servicing may h a ve been rearranged, or the
drive startup sequence has changed. Be
extremely careful during write operations, such
as copying, saving, or formatting. Data or
programs can be overwri t ten if y ou select an
incorrect drive. Ask the customer to back up
any additional sof tware from the hard disk
drive before you reload the software.
How to Diagnose Combined FRUs: If an adapter or
device consists of more than one F RU, a n y of the
FRUs might cause an error code. Before replacing
the device or adapter, remove the FRUs one by one
to see if the symptoms change.
If a newly replaced FRU does not correct the
problem: If you have reached this point of the check
procedures and were inst ructed to replace a FRU but
doing so did not correct the problem, reinstall the
original F RU and go th rough “Start” again.

Index of Symptoms, Messages, Error Codes, or Beeps
How to Use Error Messages:
error codes, and beeps combinations that occur to
diagnose failures. If more than one failure occurs,
begin the diagnosis from the first failure that
appeared. The cause of the first failure can result in
false messages, err o r cod e s, or beeps. If you did not
receive any messages, error codes, or beeps, see if
the symp t om is lis t ed in “Table 2-3 Error Symptoms
List” on page 45.
CAUTION:
POST:
machine, such as the Power-On Self Test (POST).
The machine performs the POST each time it is
powered on. Use this information throughout the
diagnostic procedures. The POST is a series of
system checks and initializations that verify the
correct operation of the base system.
When you have deemed it nec essary to
replace a FRU, and have done so, you must
run a total system check to ensur e th at no
other activity h a s been affe cted by the change.
This system c hec k can b e done through the
diagnostics program (Select Diagn os tic s, then
select and execute All Tests from PC-Doctor).
Some diagnostic aids are resident in the

different startup (boot) me thods by t he C onfiguration/
Setup Utility. “Startup Options” on page 20.
The system's default startup sequence automatically
looks for the operating system files in the hard disk if
these files are not found in the diskette.
WARNING:
Table 2-1 lists BIOS error codes, messages, and their
possible causes. Table 2-2 lists BIOS beeps and their
possible causes. Table 2-3 lists error symptoms and
their possible causes. T h e m ost l ike ly ca us e i s 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 33.
38 IBM Desktop System HMM
Remember that POST does not test all
areas, but only those that allow the system to
operate well enough to run the diagnostics
program.
If you are unable to correct the problem using these
two index tables, go to “Undetermined Problems” on
page 74.
NOTE:
1. If an error messag e a nd inc orr ect a udio response
occur, diagnose the error message first.
2. If you cannot run the diagnostics program tests but
did receive a POST error code and message, use
“Table 2-1 POST Erro r Codes and Messages List”
on page 40 to diagnose system problems.
3. If you cannot run the diagnostics program tests but
did receive a P O S T error beeps, use See “Table 22 BIOS Error Beeps List” on page 44 to diagnose
system problems.
4. If you did not receive any error message, look for a
description of your error symptoms in “Table 2-3
Error Symptoms List” on page 45.
IMPORTANT: Check all power sup ply v oltages,
switch, and jumper settings before you replace
the system board. Also check the power supply
voltages if you have a “system no-power”
condition.
5. If you are unable to corr ect the prob l em by using
the “BIOS Error Codes, Mes s age s , An d Beeps
List” table and “Error Symptom s List” table, go to

Check Procedures 53
Troubleshooting
Failing Parts or Assemblies:
generally help you trace a pr oblem t o one part or
assembly. The last step of the specific check
procedure you are using indicates that a part or
assembly is failing. You should inspect the part or
assembly before you decide to replace it. It might be
loose, dirty, or in need of a small repair. The check
procedures might lead yo u t o two, or e v en three,
possible failing parts or assem b lies. The parts that
might be failing are listed in order of the most
probable failure. Also, the F RU parts ar e defined as
replaced units and are not r epaired in the field.
Measuring Voltages:
instruct you to measure v ol tage s o n cable plugs and
electronic board connectors. If you are asked to
measure voltage at several places on a plug or
connector, a chart next to or near t he instruction
indicates the number of the pl ug or connector, the pin
numbers you should measure, the signal name, and
the correct v olta ge for the condition you are
measuring. Measure the voltage only at the pins
listed in the chart. Remember to set the meter on the
correct scale and to put the meter lea d s in the correct
position for t he volta ge you are asked to measure.
NOTE:
Use frame ground as the ground reference.
Attach the black (ground) lead of meter to
frame ground, except where specified
otherwise.
