Page 54: Introduction
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.
Page 55: Start
Star 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.
Page 56 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.
Page 57 Make sure that the monitor refresh rate is correct. Note any symptoms, messages, error codes, or beeps. Make sure that there are no diskettes or CDs in the drives. 002 - DOES AN IBM LOGO SCREEN APPEAR? (YES, READ AHEAD. NO, GO TO STEP 004.) Insert the diagnostics diskette in the diskette drive.
Page 58 005 - If the keyboard responds incorrectly, go to "Keyboard" on page 78. 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 All Tests.
Page 59 008 - DOES THE DIAGNOSTICS FINISH WITHOUT ANY ERRORS? (YES, READ AHEAD. NO, GO TO STEP 009.) If the Diagnostics \ All Tests did not detect a failure but the system still indicates a failure: Check all adapter card jumper settings. Check all adapter card switch settings.
Page 60: Index Of Symptoms, Messages, Error Codes, Or Beeps
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.
Page 61 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” on page 65. Check all power supply voltages, switch, and jumper settings before you replace the system board.

Page 70: Troubleshooting
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.
Page 71: Factory-Installed Storage Devices
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.
Page 72 Select Diagnostics from the PC-Doctor diagnostics program main menu. Select and execute Floppy Disk Test if you want to test the diskette drive. Select and execute Hard Disk Test if you want to test the hard disk drive.
