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.
47
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 Machine Types 6266, 6270, 6276, 6279,
6280 and 6286. Do not use this diskette on other models.
POST error codes and error messages are displayed on the screen after the IBM logo.
A beep will precede each error code or message. Please refer to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 50 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 voltage selector on the rear panel of the machine. Use a flat-head screwdriver to turn the voltage selector to the
voltage setting for the area in which you will be using 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. The
problem may be in the last card that you removed or something associated with it.
The Recovery CD contains pre-loaded software that may reinstall the original software and recover the system. Ensure that any data and
programs on the hard drive have a backup copy.
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.
48
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 BIOS Setup Utility screen to an attached printer, press Print Screen key, while the screen is displayed.
PLEASE 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 “Quick Power-On Self Test” from BIOS Setup.
Disconnect all external cables and devices including speakers and microphone from the system unit, except for the keyboard, mouse,

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, diagnose from the first failure that appears. 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 54.
ATTENTION: When you have replaced a FRU, you must run the diagnostics 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 PCDoctor).
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 the operating system. The system can be customized for different startup (boot)
methods by the BIOS Setup Utility. See “Advanced Setup” on page 38.
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.
NOTE: 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 beeps to 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 47.
If the problem cannot be corrected using these two index tables, go to “Undetermined Problems” on page 69.
NOTES:
If an error message and incorrect audio response occur, diagnose the error message first.
If you cannot run the diagnostics program tests but did receive a POST error code, diagnose the POST error message.
If you did not receive any error message, look for a description of your error symptoms in “Error Symptoms List” in page 54.
1. 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. (“Power Supply Cable Connector Specifications on page 103 and Layout of System
Board of Machine Types 6266, 6270, 6276, 6279, 6280 and 6286 on page 101).

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.

Introduction
This section explains the diagnostic aids, power-on self test (POST) and diagnostics program (PC-Doctor), that are available for
troubleshooting problems on the system.
73
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:
• System Board • Mouse
• Memory • Parallel Port(s)
• SVGA Controller • Serial Port(s)
• Hard Disk Drive(s) • CD-ROM Drive(s)
• Floppy Diskette Drive(s) • Sound Controller
• Keyboard
To start POST, turn on the monitor and then the system unit. The following will happen:
1. The IBM logo will appear on center of the screen.
2. At this time one of two hot-keys may be used. The F1 key, as described on screen, will cause the system 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.
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 go 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 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 DOS or other
operating system from diskette drive A or a hard disk drive or CD-ROM drive, depending on the options selected in the 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 50 to find the most likely cause and countermeasure.
74
Diagnostics Tools
IMPORTANT: This manual is intended to test the IBM Machine Types 6266, 6270, 6276, 6279, 6280 and 6286.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 CD (compact disk) 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 Diagnostics Program from Recovery CD
1. Insert the recovery CD into the CD-ROM drive then restart computer.
2. Press F1 during POST to enter BIOS Setup menu. Select and enter “BIOS Features Setup”, set “Boot Sequence to CD-ROM, A, C”.
Save and exit from BIOS Setup.
3. When screen prompts to install original software, type N to exit the installation program. Then type PCDR and press Enter to start the
diagnostics program. Follow the instructions on the screen to operate the diagnostics program.
