FRU replacement should only be considered when a recurring problem exists. When analyzing on intermittent problem, do the following: 48 ThinkPad R30/R31 HMM 1. Run the diagnostic test for the system board at least 10 times. 2. If no error is detected, do not replace any FRUs. 3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors. Undetermined Problems The diagnostic tests did not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow the procedures below to isolate the failing FRU. Verify that the power supply being used at the time of the failure is operating correctly. 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: v Non-IBM devices v Printer, external mouse & keyboard, and other external devices v Battery pack v Hard disk drive v CD-ROM drive/Diskette drive (optional) v PC Card (PCMCIA) 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 at a time. Do not replace a non-defective FRU. v Hard disk drive connection board v LCD assembly v System board MT 2656, 2657, 2676 49 ThinkPad R30 This section applies to the following models: 2656, 2657, 2676. 50 ThinkPad R30/R31 HMM Product overview...
