Introduction
This chapter contains the check procedures used to
diagnose the causes of product failures. The
diagnostic information consists of:
Start: This is the starting point for any diagnostic
action. Based on high-level symptoms, the check
procedure directs you to more detailed procedures to
help resolve machine failures.
Index of Symptoms, Messages, Error Codes, or
Beeps: The tables for BIOS Error Messages, Codes,
Beeps, and Error Symptoms list symptoms along with
their probable causes, and direct you to the
applicable check procedures to help resolve machine
failures. These tables also list the field replaceable
units (FRUs) most likely to cause a particular
problem.
Check Procedures: When the Start check
procedure or the Index of Symptoms, Messages,
Error Codes, or Beeps tables point you to a specific
check procedure, proceed to that section. If there are
any notes or instructions at the top of the page, read
them before you begin with the procedure. Carefully
read each step of the check procedure and perform
the steps as instructed. If you do not remember the
location of a specific part or test point, or an
adjustment or removal procedure, see the chapter
that contains that information. Always return to the
check procedure after you do this. In some cases,
you are referred to other check procedures to detect
the cause of the failure.
Check Procedures 33
Start
This is the entry point for all check procedures. The
check procedures use failure symptoms, Power-On
Self Test (POST) error codes, or beeps to help
determine the defective field replaceable unit (FRU).
Follow the suggested check procedures or use the
diagnostics diskette to determine the problem FRU.
IMPORTANT: Replace FRUs ONLY when it is
determined that the error is not a result of
software, loose contacts, or dirty component
surfaces. Any FRU change should be verified
by running a complete test (“Diagnostics - All
Tests” in PC-Doctor diagnostics program).
This book comes with a diagnostic program diskette.
This diskette should be used ONLY with 2274
Service Level A (SL-A) IBM Personal Computers.
Do not use this diskette 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
problem. Please refer to “Index of Symptoms,
Messages, Error Codes, or Beeps” on page 38 for
additional help.
All voltages in the check procedures are positive
unless otherwise indicated. Use frame ground for all
voltage checks unless otherwise specified.
IMPORTANT: There is a Power Override switch
located at the back of the machine, just above
the connector for the power cable. If the
system does not power on after pressing the
power button situated on the front of the
machine, please check the power cable and
the Power Override switch. If the Power
Override switch is switched on, no power is
supplied to the system.
NOTE: If the check procedures instruct you to replace
a FRU and the error message persists, an
option adapter card might be causing the
failure. Remove all option adapter cards, one
at a time, until the error changes or the
problem is no longer apparent. Replace the
last option adapter card removed.
34 IBM Desktop System HMM
The hard disk drive contains pre-loaded software. Be
sure to reload the software on the primary hard disk
drive (Drive C) when replacing it.
IMPORTANT: The drives in the system you are
servicing may have 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 overwritten if you select an
incorrect drive. Ask the customer to back up
any additional software 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 FRU, any 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 instructed to replace a FRU but
doing so did not correct the problem, reinstall the
original FRU and go through “Start” again.
If you want to print a copy of a Configuration/Setup
Utility screen to an attached printer, press Print
Screen key while the following screen is displayed.
READ THE FOLLOWING:
Human Error is a cause for concern when applied
to check procedures. It exists in every first time
set of analysis procedures. It is therefore
essential for effective and time-efficient servicing
that each stage of every procedure be verified.
(For example: When a symptom is found, or when
a symptom appears to have been cured; the
preceding steps should be repeated for accuracy
of analysis.)
001 - START
•To begin, note the following:
•Disable the setting of “Fast POST Mode” in
Configuration/Setup Utility.
•To disable or reset the power-on password, see
“Power-On Password” on page 11.

38 IBM Desktop System HMM
Index of Symptoms, Messages, Error
Codes, or Beeps
How to Use Error Messages: Use the 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, error codes, or beeps. If you did not
receive any messages, error codes, or beeps, see if
the symptom is listed in “Table 2-3 Error Symptoms
List” on page 45.
CAUTION: When you have deemed it necessary to
replace a FRU, and have done so, you must
run a total system check to ensure that no
other activity has been affected by the change.
This system check can be done through the
diagnostics program (Select Diagnostics, then
select and execute All Tests from PC-Doctor).
POST: Some diagnostic aids are resident in the
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.
After a successful POST, the system attempts to load
operating system. The system can be customized for
different startup (boot) methods by the Configuration/
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: Remember that POST does not test all
areas, but only those that allow the system to
operate well enough to run the diagnostics
program.
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. 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 33.
Check Procedures 39
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 message and incorrect audio 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 Error Codes and Messages List”
on page 40 to diagnose system problems.
3. If you cannot run the diagnostics program tests but
did receive a POST error beeps, use See “Table 2-
2 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 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.
5. If you are unable to correct the problem by using
the “BIOS Error Codes, Messages, And Beeps
List” table and “Error Symptoms List” table, go to
“Undetermined Problems” on page 74.

Troubleshooting
Failing Parts or Assemblies: The check procedures
generally help you trace a problem to 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 you to two, or even three,
possible failing parts or assemblies. The parts that
might be failing are listed in order of the most
probable failure. Also, the FRU parts are defined as
replaced units and are not repaired in the field.
Measuring Voltages: Some check procedure steps
instruct you to measure voltages on 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 the instruction
indicates the number of the plug or connector, the pin
numbers you should measure, the signal name, and
the correct voltage 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 leads in the correct
position for the voltage 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.
Factory-Installed Storage Devices
Use this check procedure to test any factory-installed
drives, including Zip drives.
ATTENTION: The customer may have customized
settings in the Configuration/Setup Utility (other
than default settings) on the computer you are
servicing. Running the Configuration/Setup
Utility might alter those settings. Take note of
the current settings and verify that the
customer settings are in place when service is
complete.

While starting Windows 98, the DDC2 monitor passes
resolution and frequency information to the system.
The system interprets the data and sets up the proper
refresh rate.
If the monitor type is set to the power saving mode,
the screen remains black and the LED lights or
flashes in amber color. When the monitor is turned on
alone, or is turned on and connected to a powered-off
system unit, the monitor LED blinks in amber color.
Under the normal operating conditions, the LED lights

Introduction
This section explains the diagnostic aids, power-on
self test (POST) and diagnostics progra
(PC-Doctor), that are available for troubleshooting
problems on the system.
Diagnostic Aids 79
Power-On Self Test
Each time you power-on the system, the power-on
self test (POST) is initiated. Several items are tested
during POST, but is for the most part transparent to
the user.
POST checks the following:
To start POST, turn on the monitor and then the
system unit. The following will happen:
1. The IBM Personal Computer logo will appear on
the screen.
2. At this time one of two hot-keys may be used. The
F1 key will cause the system Configuration/Setup
Utility menu to appear. The F9 key will switch the
graphical IBM logo screen to the traditional text-
based system startup screen, which displays BIOS
version and system memory tested. For Personal
Computer Type 2274, the F9 key will only work
after exiting Configuration/Setup Utility.
3. If an error is detected during POST, the IBM logo
screen will automatically switch to the text-based
screen and display the error message or code with
a beep. Depending on the criticality of the POST
error, the system may halt and/or display the
message “Press <F1> to enter to the Setup or
<Enter> to continue...”
If this message appears, pressing the Enter key
will allow the system to attempt to proceed despite
the reported error; pressing F1 will cause the
system Configuration/Setup Utility menu to appear.

4. If no keyboard keys are pressed, and if POST is
completed without errors, the system will then
proceed with the loading of Windows98 or other
operating system from a hard disk drive or diskette
drive A or CD-ROM drive, depending on the Start
options selected in the Configuration/Setup Utility.
If any errors are detected by POST, there will be
an error message accompanied with an error code
shown on display screen and a beep. See “Index
of Symptoms, Messages, Error Codes, or Beeps”
on page 38 to find the most likely cause and
countermeasure.
Diagnostic Aids 81
Diagnostic Diskette
WARNING: This manual is intended to test the IBM
Personal Computer Type 2274 machine type
only. Testing devices which are not included
with the original product package, including
other IBM products, prototype cards, or
modifying hardware settings may give false
errors and invalid system responses. The
diagnostics not specifically made for this model
may also report incorrect errors and
information.
The diagnostics program comes on a diskette along
with this book. This version of PC-Doctor diagnostics
program, developed by Watergate for IBM, is the
primary method of testing the computer. You can use
it to test the IBM components of the system and some
external devices. The amount of time required to test
components depends on the number of components
installed and selected. The more devices you have
attached to your system and selected in PC-Doctor,
the longer the testing will take.
Using the Diagnostic Diskette
1. Power-off the system unit.
2. Insert diagnostic diskette in drive A.
3. Power-on the system unit.
NOTE: Do not press F1 during POST. If any POST
errors appear after POST, make a note of the
errors.
4. DOS should load. During boot, verify that each
driver loads successfully. For drivers that do not
load successfully, verify that the device driver is
associated with it and is installed properly.
5. Diagnostics program (PC-Doctor) will load, then
follow the screen instructions to operate.
82 IBM Desktop System HMM
Using Diagnostic Program from
Recovery CD
1. Insert the Personal Computer recovery CD into the
CD-ROM drive then restart computer.
2. Depress F1 while POST to enter Configuration/
Setup Utility menu. Select and enter “Startup
Options”, set the first priority of boot sequence to
CD-ROM. Save and exit from Configuration/Setup
Utility.
3. When screen displays IBM Recovery Program
menu, choose “Run Diagnostics” to execute
diagnostic program.
4. Follow the instructions on the screen to operate
the diagnostics program.

Removals and Replacements
BEFORE REMOVING ANY FRU, POWER-OFF THE
COMPUTER, UNPLUG ALL POWER CORDS FROM
ELECTRICAL OUTLETS, THEN DISCONNECT ANY
INTERCONNECTING CABLES.
ATTENTION: The system board, processors, adapter
cards, DIMMs, and upgrade processors can be
damaged by electrostatic discharge. Use an
electrostatic discharge (ESD) strap to establish
personal grounding. If you don't have an ESD
strap, establish personal grounding by
touching a ground point with one hand before
touching the static-sensitive FRUs.
The arrows in the removals and replacements
procedures show the direction of movement to
remove a field-replaceable unit (FRU), to turn a
screw, or the direction to press a tab to release the
FRU.
Begin all removals by removing the cover (and rear
cover, if applicable).
When other FRUs must be removed prior to removing
the failing FRU, they are listed at the top of the page.
Go to the removal procedure for each FRU listed,
remove the FRU, and then continue with the removal
of the failing FRU.
To replace a FRU, reverse the removal procedure
and follow any notes that pertain to replacement.
Before disconnecting any cables, note their location
and orientation. Reinstall any new FRUs with cabling
in their original location.
General Information 87
Handling ESD-Sensitive Parts
Many electronic parts are sensitive to electrostatic
discharge (ESD). To prevent damage when working
with ESD-sensitive parts, observe the following
instructions. Do these in addition to taking all the
usual precautions, such as switching off the power
and unplugging the power cord.
•Keep the ESD-sensitive part in its original shipping
container (or special ESD bag) until you are ready
to install the part.
•Make the fewest possible movements with your
body to prevent an increase of static electricity
from clothing fibers, carpets, and furniture.
•Put the ESD wrist strap on your wrist. Ensure the
machine is turned off. Connect the wrist strap to
the serial bracket mounting screw. This discharges
any static electricity in your body to the machine
frame.
•Hold the ESD-sensitive part by its edge connector
shroud (cover). Do not touch its pins. If you are
removing a plug-able module, use the correct
tools.
•Do not place the ESD-sensitive part on the
machine cover or on a metal table. If you need to
put down the ESD-sensitive part for any reason,
put it into it's original container.
•Machine covers and metal tables are electrical
grounds. They increase the risk of damage
because they make a discharge path from your
body through the ESD-sensitive part. (Large metal
objects can be discharge paths without being
grounded.)
•Prevent ESD-sensitive parts from being
accidentally touched by other persons. Reinstall
machine covers when you are not working on the
machine.
•If possible, keep all ESD-sensitive parts in a
grounded metal cabinet.
•Be extra careful when working with ESD-sensitive
parts while cold-weather heating is being used.
Low humidity increases static electricity.

Identifying the Parts of the System Unit
This computer system has four bays that can hold
5.25-inch and 3.5-inch drives. Additional devices
can be installed in the empty bays.
Diskette drives in this unit use the standard diskette
advanced technology (AT) interface. Hard disk drives
in this unit use an integrated drive electronics (IDE)
AT interface. This computer supports the American
National Standards Institute (ANSI) standard for AT
attachment disk drives.
It also has interface slots for installation of additional
cards devices. Industry Standard Architecture (ISA)
and Peripheral Component Interconnect (PCI)
adapter cards are both supported.
1. Bay 1.
This drive bay can hold a 5.25-inch half high drive
or a 5.25-inch slim drive. A 3.5-inch drive can be
accommodated with additional brackets. This bay
can hold a CD-ROM, DVD-ROM, diskette, hard
disk, tape, or Zip drive.
2. Bay 2.
This drive bay can hold a 5.25-inch half high drive
or a 5.25-inch slim drive. A 3.5-inch drive can be
accommodated with additional brackets. This bay

disk, tape, or Zip drive.
3. Bay 3.
This drive bay can hold a 3.5-inch slim drive, such
as a diskette, hard disk, tape, or Zip drive.
4. Bay 4.
This drive bay is designed for a 3.5-inch diskette
drive.
5. Adapter card connectors.
Adapter card connectors are sockets on the
system board into which adapter cards are
installed. Your system board has four adapter card
connectors. One of these connectors is for an ISA
card and three are for PCI cards. Since two of
these connectors are shared (one ISA and one
PCI next to it), only three cards (excluding the AGP
video card) can be installed at any time.
6. Adapter cards.
Adapter cards add to your computer's capabilities.
7. Adapter card slots.
Adapter card slots are the holes in the back of the
tower that permit external access to adapter cards.
8. System board.
The system board is the main circuit board in your
computer. It contains the processor, also known as
the central processing unit (CPU), and the system
battery. It also contains sockets for memory
modules, connectors for adapter cards, and
connectors for the cables that carry data to and
from drives.
9. Power supply.
The power supply provides the electricity that is
used by the other hardware components in your
computer. This model may come with a 95
power supply.

2Note: The IEEE-1394 internal cable bundle
needs an outer shield to minimize internal
crosstalk within the cable construction. The outer
EMI containment shield for the IEEE-1394 func-
tion will be provided by the overall P&D cable
shield. If the internal bundle shield for IEEE-1394
is required, this may be terminated to pin #18. It
is recommended that this implementation be
evaluated in the case where both Charge Power
return and the IEEE-1394 internal cable bundle
shield will be commoned to pin #18.
