If the problem is not corrected, replace the device and then the system board. TrackPoint III Checkout If the TrackPoint III does not work, check the configuration in the ThinkPad Features program. If the configuration of the TrackPoint III is disabled, select Enable to enable it. If this does not correct the TrackPoint III problem, continue with the following. The TrackPoint III does automatic compensations to adjust the pointer sensor. During this process, the pointer moves on the screen automatically for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the TrackPoint III pointer while the computer is powered on or while the system is running, or when readjustment is required because the temperature has exceeded its normal temperature range. This symptom does not indicate a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. If a click button problem or pointing stick problem occurs, do the following: 1. Go to the Easy-Setup screen. 2. Select an item with the pointing stick. 3. Press either the left or right click button. 4. Verify that both buttons work correctly. If either the pointing stick or the click button do not work, do the following actions one at a time to correct the problem. Do not replace a nondefective FRU. Reseat the keyboard cables. Replace the keyboard. Replace the system board. Diskette Drive Checkout Do the following to isolate the problem to a controller, drive, or diskette. A scratch, write-enabled, nondefective 2HD diskette is required. FDD-1 represents an external diskette drive attached through the external diskette drive connector. FDD-2 represents the port replicator. Warning: 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: 1. Go to the advanced diagnostic mode by pressing Ctrl+A from the diagnostic menu. 2. Select Tool; then select the FDD-1 or FDD-2 icon and press the spacebar. A √ mark appears next to the selected icon. 130 IBM Mobile Systems HMM
