Aptiva - 2140/2142 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 and Utilities CD to determine the problem FRU.
The Diagnostics and Utilities program comes on one CD supplied with this book and the system. Use only this CD for all Type 2140 and Type 2142 IBM Aptiva Personal Computers.
The Diagnostics and Utilities 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 preloaded software. Refer to "Software Installation Procedure" on page 4-20 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.
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.
2. After one or more 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 might take a minute or more for the system to respond with error messages or beeps.
If error codes occur for:
Disk Drives
I/O Devices
Plug and Play Devices
Go first to the Setup Utility to assure devices are installed.
If you have an XX62 error with no other error codes, run the Setup Utility (see "Using the Setup Utility" on page 1-18 of the HMM) and note any flagged options. Note the XX62 error or flagged option and try to add it from the Configuration/Setup Utility screen. If the option cannot be added, 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" .
