Aptiva - 2144/2168 (SL-C) 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 Advanced Diagnostics diskettes to determine the problem FRU.

The Advanced Diagnostics program comes on one diskette packaged together with this book. Use only this diskette, labeled "For Machine Types 2144 and 2168," for all Service Level C IBM Aptiva Personal Computers.

The Advanced 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 may 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 preloaded software. Refer to "Software Installation Procedure" in topic 4.4 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 carefully 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 may 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.

POST Error Codes: A POST error code can occur in three ways:

1. Under the System Memory count at the upper-left corner of the screen.

Note: A memory error can appear without the memory count as a 203
address error.

2. After two beeps, followed by an error code and/or explanatory message.

3. As a sequence of beeps with no other messages or error codes
displayed.

Note: It may take a minute or more for the system to respond with
error messages or beeps.

If you have an XX62 error with no other error codes, run the Configuration
Utility (see "Starting the Configuration Utility" in topic 1.5.1.1) and
note any flagged options. Note the XX62 error or flagged option and try
to add it from the Configuration Utility screen. If the option cannot be
added, go to "Index of Symptoms, Messages, Error Codes, or Beeps" in
topic 2.2 for additional help.

If you want to print a copy of a Configuration 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" in topic 2.2.

To begin this check, note the following:

• To disable or reset the power-on password, see "Power-On Password Clear--Type C-1 or Type C-2 System Boards" in topic 1.4 of the HMM.
  
• Look on the system board for the type of board (Type C-1 or C-2), and refer to "System Board Layouts--Machine Types 2144 and 2168" in topic 5.1of the HMM for the correct jumper positions.
  
• Disconnect all external cables and devices from the system unit, except for the keyboard, mouse, and monitor.
  
• Power off the system unit whenever removing or replacing FRUs.
  
• Remove all adapter cards from the riser card, except for the factory-installed FAX/modem adapter card (if installed) and any IBM Aptiva factory-installed adapter cards. Some riser cards have a VESA local bus connector.
  
• Remove all telephone cables from the modem (if installed).
  
• Disconnect any drives except:

› 3.5-in. diskette drive
› Hard disk drive (some machines may have up to 4 hard disk drives installed.)
› 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.
  
• Ensure sound volume control is not turned down and the speakers are
  powered on.
  
• 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 "Detachable Monitor I/O Signal Cable Connector Test Points" in topic 5.7 of the HMM for pin identification.

High voltage Northern and Southern Hemisphere monitors may come with a voltage selector (110 V-220 V) switch. The 145-W power supply may have a voltage selector (110 V-220 V) switch. Match the switch to the line voltage.

• Ensure the correct monitor frequency is set in the Configuration Utility for the monitor used with the system (see "Using the Configuration Utility" in topic 1.5.1). If the monitor frequency is set incorrectly, the monitor may not be readable in certain modes. To determine the correct monitor frequency, look on the monitor for the part number and refer to Table A-2 in topic A.0. If the monitor is not shown in Table A-2 in topic A.0, see the product information shipped with the monitor. Set the monitor frequency equal to or less than the monitor's maximum horizontal frequency (also known as the horizontal scan rate). See "Refresh Rates and Monitor Frequencies" in topic 1.3.1.
• 
  Note any symptoms, messages, error codes, or beeps.
  Make sure there are no diskettes or CDs in the drives.
