Troubleshooting (Aptiva 2170/71/72/74/87/90 - SL-A)

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, including Zip 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.

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

001 - START

•  Insert the diagnostics diskette into the diskette drive.
•  Power-off then power-on the system unit.

  002 - DO ANY POST MESSAGES, ERROR CODES, BEEPS, OR SYMPTOMS OCCUR?
   (YES, READ AHEAD. NO, GO TO STEP 003)

•  Go to 'Index of Symptoms, Messages, Error Codes, or Beeps'.
•  End.

  003 -

•  Select Utility from the menu.
•  Select and execute Tech Support Form from the menu to generate a system configuration report.
•  Compare the system configuration list with the actual devices installed in system.

  NOTE: If necessary, remove the cover and visually compare the devices
   installed in the system unit to those shown in the Tech Support Form.

  004 - IF THE NUMBER OF DISKETTE, HARD DISK, OR CD-ROM DRIVE IS NOT CORRECT,
   READ AHEAD, OR GO TO STEP 005.

•  Check the cable installation of all disk drives. (See 'Machine Type 2170, 2171/72, 2174, 2187, 2190  System Board Jumpers and Connectors').
  •  Floppy diskette drive should be connected to the system board connector
     CN10 for 2170, CN5 for 2171/2172, J28 for 2174, J102 for 2187/2190.
  •  IDE Primary Channel Master and Slave Drives in BIOS Setup should be connected to the system board connector
     CN11 for 2170, CN11 for 2171/2172, J24 for 2174, J101 for 2187/2190.
  •  IDE Secondary Channel Master and Slave Drives in BIOS Setup should be connected to the system board connector
     CN12 for 2170, CN10 for 2171/2172, J19 for 2174, J104 for 2187/2190.

  NOTE: The CD-ROM drive that comes with system unit should be configured as IDE  Secondary Channel Master device.

•  Check all power supply voltages, switch, and jumper settings before you replace the system board. (See 'Machine Type 2170, 2171/72, 2174, 2187, 2190  System Board Jumpers and Connectors').
•  Check the power supply voltages if you have a 'system no-power' condition.
   See 'Power Supply Connectors and Voltages'.
•  Check the hard disk and CD-ROM drives jumper settings.
   See '3.5-In. Hard Disk Drive Jumper Settings'. Check the voltages of all disk
   drive power connectors. See 'Power Supply Connectors and Voltages'.
•  Correct the parameter settings under Disk Drives in the BIOS Setup. See 'Hard Disk Drive'.
  •  In the BIOS Setup, check that the correct drive size is set for the flagged drive shown in the  System Information. See 'Viewing System Information, Video Information and Model Information'.

•  Enter BIOS Setup and load default settings.
   If the problem remains, check the continuity on the drive and the cable and replace it if necessary.
   If that does not fix the problem, replace the system board.

•  End.

  005 -

•  Select Diagnostics from the PC-Doctor diagnostics program main menu.
   Select and execute Floppy Disk Test if you want to test diskette drive.
   Select and execute Hard Disk Test if you want to test hard disk drive.
•  Select Interactive Tests from the PC-Doctor diagnostics program main menu,
   then select and execute CD-ROM/DVD Test if you want to test CD-ROM drive.
•  If the diagnostics program did not detect a failure, but the system still displays a failure:
  •  If an error or other symptom appears, go to 'Index of Symptoms, Messages, Error Codes, or Beeps'.
  •  If no error can be detected or the symptom is intermittent, go to 'Undetermined Problems'.

•  End.
