Note: If you cannot find a symptom or an error in this list and the problem 
remains, see “Undetermined Problems”.
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. Spare Part 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 Main board in loop mode at least 
10 times.
2.  If no error is detected, do not replace any Spare Part.
3.  If any error is detected, replace the Spare Part shown by the Spare Part 
code. Rerun the test to verify that no more errors exist.
Undetermined Problems
You are here because the diagnostic tests did not identify which adapter or 
device failed, installed devices are incorrect, a short circuit is suspected, or 
System configuration does not 
match the installed devices.1.  Enter BIOS Utility to execute load setup default 
settings, then reboot system.

programs, no sound comes from

the system is inoperative. Follow these procedures to isolate the failing Spare 
Part (do not isolate nondefective Spare Part).
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 Systems Check”):
1.  Power off the computer.
2.  Visually check them for damage. If any problems are found, replace the 
Spare Part.
3.  Remove or disconnect all of the following devices:
a.  Non-Acer devices
b.  Devices attached to the port replicator
c.  Printer, mouse, and other external devices
d.  Battery pack
e.  Hard disk drive
f.  DIMM 
g.  Diskette drive
h.  PC 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 Spare Part.
7.  If the problem remains, replace the following Spare Part one at a time. Do 
not replace a nondefective Spare Part:
a.  Main board
b.  LCD assembly
