Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists.

When analyzing an intermittent problem, do the following:

1Run the advanced diagnostic test for the system board in loop mode at least 10 times.

•If any error is detected, replace the FRU.

•If no error is detected, do not replace any FRU.

2Rerun the test to verify that there are no more errors.

Undetermined Problems

The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative.

Follow these procedures to isolate the failing FRU (do not isolate a non-defective FRU).

Important

Verify that all attached devices are supported by the computer.

Important

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Check” on page xxvi.)

To isolate a failing FRU:

1Power-off the computer.

2Visually check them for damage. If any problems are found, replace the FRU.

3Remove or disconnect all of the following devices:

•Non-Gateway devices

•Printer, mouse, and other external devices

•Battery pack

•Hard disk drive(s)

•DIMM

•CD-ROM/Diskette drive Module

•PC Cards

4Power-on the computer.

5Determine if the problem has changed.
