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 problems, follow the procedures below:
1.Run the advanced diagnostic test for the system 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 t he test to verify that there are no more errors. 
						

							
Chapter 485
Undetermined Problems
The diagnostic problems does not identify which devices fail, which devices are incorrectly 
installed, whether a short circuit happens, or whether the system is inoperative.
NOTE:  Verify if all devices attached  are supported by the computer.
NOTE:  Verify if the power supply used at the time of fa ilure is operating correctly. You can refer to “Power 
System Check”.
Follow the procedures below to  isolate the failing FRU. Do not isolate non-defective FRU.
1.Power off the computer.
2.Visually check the devices. If any problems are found, replace the FRU.
3.Remove or disconnect all of the following devices:
•Non-Acer devices
• Printer, mouse, and other external devices
• Battery Pack
• Hard disk drive
• DIMM
• CD-ROM / Diskette drive module
• PC cards
4.
Power on the computer.
5.Determine if the problem has been resolved.
6.If the problem does not recur, reconnect the removed devices one at a time until you find the 
failed FRU.
7.If the problem remains, replace the following FRU  one at a time. Do not replace a non-defective 
FRU.
