Low Range: 90 Vac to 132 Vac

High Range: 180 Vac to 264 Vac

General Information 27

Operating Requirements

All machines require two power inputs: one for the system unit and one for the monitor display.

The system units come with a voltage selector switch, allowing selection of voltage of either 115 Vac or 230 Vac. This switch must be in the 230 Vac position when the machine is plugged into a 230 Vac electrical outlet.

The required power input for the monitor (Not included with some models) shipped with the system unit is auto-sensing type and does not require any voltage switch adjustment.

Check Procedures 29

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 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.

30 IBM Desktop System HMM

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 CD 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 - Run Normal Test” in PC-Doctor diagnostics program).

NOTE: The disagnostic program diskette can be created from the Recovery CD if the user has a USB diskette drive attached.

The diagnostic program diskette diskette should be used ONLY with 6644/6645/6646 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 system problem. Please refer to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36 for additional help.

All voltages in the check procedures are positive unless otherwise indicated. Use frame ground for all voltage checks unless otherwise specified.

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.

The hard disk drive contains pre-loaded software. Refer to “Software Recovery Procedure” on page 102, to reinstall the original 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

Check Procedures 31

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 BIOS 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 BIOS Setup.

To disable or reset the power-on password, see “Power-On Password” on page 8.

Disconnect all external cables and devices from the system unit, except for the keyboard, mouse, and monitor.

Power off the system unit (unplug the power cord) before moving it or when replacing FRUs.

32 IBM Desktop System HMM

Remove all adapter cards, except for the factoryinstalled adapter cards.

Disconnect all drives except:

-Hard disk drive

-IBM factory-installed devices (such as a CDROM drive)

Ensure that all power cords and cables are connected properly.

Ensure that the monitor brightness and contrast controls are not turned down.

Power on the system unit.

NOTE: Some monitors have a detachable system I/O signal cable between the monitor and the system unit. In this case, check this signal cable before replacing the unit. See “Monitor Port Signals” on page 117 for pin identification.

Ensure correct monitor refresh rate.

Note any symptoms, messages, error codes, or beeps.

Make sure that there are no CD in the drives.

002 - DOES AN IBM LOGO SCREEN APPEAR? (YES, READ AHEAD. NO, GO TO STEP 004.)

Insert diagnostics CD in the CD-ROM drive or the the diagnostic diskette in a USB attached diskette drive.

003 - DOES SYSTEM LOAD THE DIAGNOSTICS PROGRAM ? (YES, READ AHEAD. NO, GO TO STEP 004.)

Follow the instructions on the screen and select Utility from the diagnostics program menu.

Select Tech Support Form from the menu, press F5 to execute, then generate a system configuration report.

Compare the system configuration list with the actual devices installed in system.

NOTE: If necessary, remove the machine cover and visually compare the devices installed in system to those shown in the system configuration report.

Go to step 006.

Check Procedures 33

004 - DO ANY MESSAGES, ERROR CODES, OR SYMPTOMS APPEAR? (YES, READ AHEAD. NO, GO TO STEP 005)

Go to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36.

End.

005 -

If the keyboard responds incorrectly, go to “Keyboard” on page 65.

If monitor problems appear, such as jittering, shifting, or being out of focus, go to “Monitor” on page 70.

006 - DOES THE SYSTEM CONFIGURATION REPORT CORRECTLY IDENTIFY THE DEVICES INSTALLED IN SYSTEM? (YES, READ AHEAD. NO, GO TO STEP 007.)

Select Diagnostics from the diagnostics program menu.

Select and execute Run Normal Test. - Go to step 008.

007 -

The system configuration report shows only those devices supported by the diagnostics CD.

If a device is missing from the list and is not factory installed, refer to the service manual provided for that device.

008 - DO THE DIAGNOSTICS FINISH WITHOUT ANY ERRORS? (YES, READ AHEAD. NO, GO TO STEP 009.)

If the Diagnostics \ Run Normal Test did not detect a failure but the system still indicates a failure:

-Check all adapter card jumper settings.

-Check all adapter card switch settings.

-Check all adapter card cables and connectors. Make sure that all of the above are set correctly and show the correct voltages and continuity. Replace any defective cables or adapter cards. See “Parts/Test Point Locations” on page 103.

-Run the Diagnostics \ Run Normal Test again.

34 IBM Desktop System HMM

-If an error or other symptom is displayed, go to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36.

-If no error can be detected or the symptom is intermittent, go to “Undetermined Problems” on page 72.

End

009 -

If the last test stops and you cannot continue, first make sure all switches, power connectors, cables, and jumpers are set correctly and show the correct voltages and continuity.

Take note of any messages, error codes, beeps, or new symptoms. Go to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36.

If there is no error symptom or the error symptom is intermittent, go to “Undetermined Problems” on page 72.

Check Procedures 35

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 48.

IMPORTANT: 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 Run Normal Test 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 operating system. The system can be customized for different startup (boot) methods by the BIOS Setup Utility. “Date and Time” on page 21.

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 CD.

IMPORTANT: 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

36 IBM Desktop System HMM

“Action/FRU” column. When servicing a system, always begin with “Start” on page 31.

If you are unable to correct the problem using these two index tables, go to “Undetermined Problems” on page 72.

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 38 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 45 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 48.

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 72.

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.

ATTENTION: The customer may have customized settings in the Setup Utility (other than default settings) on the computer you are servicing. Running the 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.

Check Procedures 55

NOTE: If you cannot access the hard disk drive or load a CD from the CD-ROM drive, make sure that the BIOS Setup Utility has the startup sequence set with CD ROM and hard disk drives.

001 - START

Insert the diagnostics program CD into the CDROM drive.
