To update the flash memory, do the following: 1. Get the appropriate diskette containing the update. 2. Insert the System Program Service Diskette into drive A and power on the computer. 3. Select Update system programs from the menu. System Board and CPU Card Checkout The processing functions are performed by both the system board and the CPU card. Processor problems can be caused by either FRU. However, the CPU card generally has a lower probability of failure. When a numeric code calls the system board or the CPU card as a FRU, or the CPU card is called by a diagnostic test by showing FRU code 11, use the following procedure to isolate the problem: 1. Run the system board test to verify the symptom. This test verifies both the system board and the CPU card. If no error is detected, return to "Checkout Guide" on page 96. 2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Transfer the CPU card from the old system board to the new system board. 3. If FRU code 11 appears, reseat the CPU card. 4. Rerun the test to verify the fix. 5. If FRU code 11 remains, replace the CPU card. If above procedure does not correct the problem, go to "Undetermined Problems" on page 116. Keyboard/Auxiliary Input Device Checkout Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the three flexible cables extending from the keyboard are correctly seated in the connectors on the keyboard card. If the keyboard cable connections are correct, check the keyboard card. 98 IBM Mobile Systems - ThinkPad HMM Volume 3
