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, electros tatic discharge, or software errors. FRU replacement 
should be considered only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the advanced diagnostic test for the syst em board in loop mode at least 10 times.
2. If no error is detected,  do not replace any FRU.
3. If any error is detected, replace  the FRU. Rerun 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 faili ng FRU (do not isolate non-defective FRU).
NOTE:  Verify that all attached devices  are supported by the computer.
NOTE:  Verify that the power supply being used at the time  of the failure is operating correctly. (See “Power 
System Check” on page 71):
1. Power-off the computer.
2. Visually check them for damage. If an y problems are found, replace the FRU.

‰ Hard disk drive
‰ DIMM 
‰ CD-ROM/Diskette drive Module
‰ PC Cards
4. Power-on the computer.
5. Determine if the problem has changed.
6. If the problem does not recur, reconnect the remove d devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRU one  at a time. Do not replace a non-defective FRU:
