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 the system is
inoperative. Follow these procedures to isolate the failing
FRU (do not isolate nondefective FRUs).
Verify that all attached devices are supported by the
computer.
Verify that the power supply being used at the time of the
failure is operating correctly. (See “Power Systems
Checkout” on page 30):
1. Power off the computer.
2. Visually check the attached devices and power supply
for damage. If any problems are found, replace the
FRU.
3. Remove or disconnect all of the following devices:
a. Non-IBM devices.
b. Devices attached to the port replicator.
c. Printer, mouse, and other external devices.
d. Battery pack.
e. Hard disk drive.
f. External diskette drive.
g. DIMM.
h. PC Cards.
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not remain, reconnect the
removed devices one at a time until you find the
failing FRU.
7. If the problem remains, replace the following FRUs
one at a time. Do not replace a nondefective FRU.
a. System board.
b. LCD assembly.
