TP 365X/XD - Symptom-To-FRU-Index

Applicable to: World-Wide

Symptom-to-FRU Index:
The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first.

Note:
Perform the FRU replacement or actions in the sequence shown in the 'FRU/Action— columns. If a FRU did not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU.

This index can also be used to help you decide which FRUs to have available when servicing a computer.
Numeric error codes show the errors detected in POST or system operation. In the following error codes ,X can be any number.

If no codes are available, use narrative symptoms.

If the symptom is not listed, go to 'Undetermined Problems—.

Note:
For any IBM device not supported by the diagnostic codes in this ThinkPad computer, see the manual for that device.

See 'Port Replicator Checkout— in the 'Common Devices Checkout— section.

PCMCIA Slots Assembly

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. FRU replacement should only be considered when a recurring problem 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. Hard disk drive
f. Internal diskette drive or CD-ROM drive
g. DIMM
h. PC Cards
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 still remains, remove the backup battery and wait for 3 minutes; then replace the backup battery and set current date and time.
8. Determine if the problem has changed.
9. If the problem remains, replace the following FRUs one at a time. Do not replace a non-defective FRU.
