|
Symptom/Error |
FRU/Action |
|
PCMCIA slot pin is damaged. |
1. System Board |
Note:
If you cannot find a symptom or 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. FRUs replacement should only be considered when recurring problems exists.
When analyzing the intermittent problem, do the following:
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 FRUs.
3. If any error is detected, replace the FRU shown by the FRU 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 the system is inoperative. Follow the procedures below to isolate the failing FRU (do not isolate non-defective 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´.)
1. Power-off the computer.
2. Check the cables, wires, and connectors for short circuits and open circuits. Visually check them 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 expansion bus connector
c. Printer, mouse, and other external devices
d. Battery pack
e. IC DRAM card
f. PC cards
Note:
Remember that removing the hard disk drive, an IC DRAM card, or any adapter or device, might cause configuration errors. Ignore error code 174.
4. Power-on the computer.
5. Determine if the problem has changed.
6. If the problem does not occur again, reconnect the removed devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRUs one ata time. Do not replace a non-defective FRU.
- Modem card (if installed)
- LCD assembly
- System board
