Symptoms (Verified) Symptoms cannot be re-created (Intermittent problems). Go To Use the customer-reported symptoms and go to "Symptom-to-FRU Index" on page 21. Diskette Drive Checkout Do the following to isolate the problem to a controller, drive, or diskette. A blank, write-enabled, formatted 2HD diskette is required. FDD-1 represents an external diskette drive attached through the external diskette drive connector. FDD-2 represents the external diskette drive attached to the port replicator. Attention: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device: See "Running the Diagnostics" on page 33 for details. 1. Go to the advanced diagnostic mode by pressing Ctrl+A from the Easy-Setup test menu. 2. Click on Exit twice. 3. Click on FDD-1 or FDD-2 to start the test. 4. Insert the blank diskette when instructed and follow the instructions on the screen. 5. If the controller test detects an error, FRU code 10 appears. Replace the system board. 6. If the controller test runs without errors, the drive read/write tests start automatically. If a drive test detects an error, FRU code 50 for FDD-1 or 51 for FDD-2 appears. If the diskette itself is known to be good, replace the drive. 7. If the FDD-2 test detects an error, move the drive to the computer's diskette drive connector directly, if possible, and test it again as FDD-1. If no errors occur in the FDD-1 position, the drive is not defective. Go to "Port Replicator Checkout" on page 13 to isolate the port replicator problem. Keyboard or Auxiliary Input Device Checkout If the internal keyboard does not work or an unexpected character appears, make sure that the flexible keyboard cable is firmly connected to the system board. If it is firmly connected, then run the Keyboard Test. If an external keyboard is connected, remove it before running the ThinkPad 560Z HMM 11
