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:
1.Run the diagnostic test for several times to isolate the problem.
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.
If an error is detected by the main battery test, see “Check the Power Adapter” on page 63
If an error is detected by the display test, see “Index of Symptom-to-FRU Error Message” on page 76 .
If an error is detected by the floppy disk drive test, see “External Diskette Drive Check” on page 61.
If an error is detected by the keyboard test, see “Keyboard or Auxiliary Input Device Check” on page 61. 
						

							Chapter 480
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 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 62):
1.Power-off the computer.
2.Visually check them for damage. If any problems are found, replace the FRU.
3.Remove or disconnect all of the following devices:
TNon-Acer devices
TPrinter, mouse, and other external devices
TBattery pack
THard disk drive
TDIMM 
TCD-ROM/Diskette drive Module
TPC Cards
4.Power-on the computer.
5.Determine if the problem has changed.
6.If the problem does not recur, reconnect the removed 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:
