Aptiva - 2136 Diagnostics - Start
Applicable to: World-Wide
This is the entry point for all check procedures. The check procedures use failure symptoms, POST error codes, or beeps to help determine the failing field replaceable unit (FRU). Follow the suggested check procedures or use the Diagnostics Diskette to determine the problem FRU.
Important: Do not replace an FRU unless you can determine the error is not caused by software, loose-contact, or dirt on
component surface. Also, any change of the FRU should be verified by a complete test ("Diagnostics \ All Test" in PC-Doctor diagnostic program).
The diagnostics program comes on one diskette supplied with this book. Use only this diskette for 2136 Service Level A (SL-A) IBM Aptiva Personal Computers. Note: The Diagnostics Diskette is not a bootable diskette. See "Creating a Boot Diskette With Drivers" in "Diagnostic Aids" on page 3-5 of the HMM for detailed information about making a bootable Diagnostics Diskette.
The diagnostics program is intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid system responses.
All voltages in the check procedures are positive unless otherwise shown. 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 remains the same, 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 Installation Procedure" on page 4-34 of the HMM to reinstall the original software. Be sure to reload the software on the primary hard disk drive (drive C) when replacing it.
Note: The drives in the system you are servicing might have been re- arranged, or the drive startup sequence, 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 take any action.
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 you have been directed here from another check procedure and were instructed to replace the system board, and that does not correct
the problem, reinstall the original system board and go through "START" again.
A POST error code and message can occur when system is powered-on until the after of IBM logo shown on screen and one beep issued. Please go to "Index of Symptoms, Messages, Error Codes, or Beeps" 
for additional help.
If you want to print a copy of a Setup Utility screen on an attached printer, press Print Screen while the screen is displayed.
How to Use Error Messages: Use the messages, error codes, and beep combinations that occur to diagnose failures. If more than one failure occurs, diagnose the first failure first. 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 "Index of Symptoms, Messages, Error Codes, or Beeps" .
Attention: When you have deemed it necessary to replace a FRU, and have then done so, you must then run a total system
check to ensure that no other activity has been affected by the change. This System Check can be made through PC-Doctor (Diagnostics \ All Test).
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 is 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 this check, note the following:
- To disable or reset the power-on password, see "Power-On Password" .
- Disconnect all external cables and devices including speakers and microphone from the system unit, except for the keyboard, mouse, and monitor.
- Power-off the system unit whenever the machine is to be removed or replaced FRUs.
- Remove all adapter cards from the riser card, except for the factory-installed Audio-I/O card or modem adapter card and any
other IBM Aptiva factory-installed adapter cards.
- Disconnect any drives except:
À 3.5-in. diskette drive
À Hard disk drive (some machines can have up to 4 hard disk drives installed.)
À IBM Aptiva factory-installed devices (such as a CD-ROM drive).
- Ensure all power cords and cables are connected properly.
- Ensure 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 either case,
check the power cord or cable before replacing the unit. See "Monitor Port Signals" on page 5-17 of the HMM for pin identification. High voltage Northern and Southern Hemisphere monitors might come with a voltage selector (110 V-220 V) switch.
- Ensure correct monitor refresh rate. See "Refresh Rates and Monitor Frequencies" on page 1-14 of the HMM.
- Note any symptoms, messages, error codes, or beeps.
- Make sure there are no diskette or CD in the drives.
002 - DOES THE SYSTEM COMPLETE POST WITH ONE SHORT BEEP AND DOES AN IBM LOGO SCREEN APPEAR? (YES, READ AHEAD. NO, GO TO STEP 004.)
- Insert the system Bootable Diagnostics Diskette in the diskette drive. (See "Creating a Boot Disk With Drivers" in "Diagnostic Aids" on page 3-5 of the HMM for detailed information about making a Bootable Diagnostics Diskette.)
003 - DOES THE SYSTEM LOAD THE DIAGNOSTIC PROGRAM FROM THE DISKETTE DRIVE WHEN POWERED OFF AND THEN ON? (YES, READ AHEAD. NO, GO TO STEP 004.)
- Select Utility on the menu.
- Select Tech Support Form on the menu, press F5 to execute, then generate a hardware configuration report.
- Compare the system configuration list with the actual devices installed in the system unit.
Note: If necessary, remove the cover and visually compare the devices installed in the system unit to those shown in the
hardware configuration report.
- Go to step 006
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" .
005 --
If the keyboard responds incorrectly, go to "Keyboard" .
- If the monitor shows problems, such as jittering, shifting, or being out of focus, go to "Monitor" and run the Diagnostics tests.
006 - DOES THE HARDWARE CONFIGURATION REPORT CORRECTLY IDENTIFY THE DEVICES INSTALLED IN THE
SYSTEM UNIT? (YES, READ AHEAD. NO, GO TO STEP 007.)
- Select Diagnostics from the menu.
- Select All Tests from the menu.
- Go to step 008
007 -
The Hardware Configuration Report shows only those devices supported by the Diagnostics Diskette and only factory-installed
devices for the model you are servicing. If a device is missing from the list and is not factory installed, refer to the service manual provided for that device. (Refer to the Appendix B, "Model/Monitor Configurations and FRU Part Numbers" to determine
the factory-installed devices in the model you are servicing.) If a factory-installed drive device or adapter card is not listed in the
Hardware Configuration Report, go to "Diagnostics for Factory-Installed Riser Card, or Audio-I/O Card Not Supported by Diagnostics Program" .
008 - DOES THE DIAGNOSTICS\ALL TEST FINISH WITHOUT ERROR CODES? (YES, READ AHEAD. NO, GO TO STEP 009.)
- If the DIAGNOSTICS\ALL TEST did not detect a failure. If the system still displays a failure:
À Check all adapter card jumper settings.
À Check all adapter card switch settings.
À Check all adapter card cables and connectors for proper installation.
À Make sure all of the above are set correctly and show the correct voltages and continuity. Replace any defective
cables or adapter cards. See "Power Supply" , "System Board Layout" .
- Run the DIAGNOSTICS\ALL TEST again.
- If an error or other symptom is displayed, go to "Index of Symptoms, Messages, Error Codes, or Beeps" .
- If no error can be detected or the symptom is intermittent, go to "Undetermined Problem" .
- 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.
- Make note of any messages, error codes, beeps, or new symptoms. Go to "Index of Symptoms, Messages, Error Codes, or
Beeps" .
