Undetermined Problems

Undetermined Problems

Perform the following procedures to isolate the failing FRU if the diagnostics tests did not identify which adapter or device failed, or whether the installed devices are incorrect, a short circuit is suspected, or the system is inoperative.

NOTE: Do not replace a nondefective FRU.

Before performing these procedures, perform the following actions:

  1.  Power-off the computer.
  2.  Check the cables, wires, and connectors for  short circuits and open circuits.  Visually check them for damage.  If any problems are found, replace the FRU.
  3.  Remove or disconnect all of the following devices:

    1.  Non-IBM devices
    2.  Devices attached to the expansion bus connector
    3.  Printer, mouse, and other external devices
    4.  Battery pack
    5.  Hard disk drive
    6.  Diskette drive or the device attached to the diskette drive  connector
    7.  SO-DIMM card
    8.  PCMCIA cards

      NOTE:  Remember that removing the hard disk drive,  a SO-DIMM card,  or any adapter or device will cause configuration errors.  Error code 162 will occur.

  4.  Power-on the computer.
  5.  Determine whether the problem has changed.
  6.  If the problem does not occur again,  reconnect the removed devices one  at a time until you find the failing FRU.
  7.  If the problem remains, replace the following FRUs one at a time.

    NOTE:   Do not replace a nondefective FRU.
