7. Ensure that the AC Adapter is plugged into the computer; then power on the computer. 8. Charging of the standby battery starts immediately. A depleted battery needs approximately 30 minutes to be recharged to the operational voltage of +3.5 V dc. 9. Unplug the AC Adapter. 10. Verify the standby battery function by removing and installing the battery pack during suspend mode. Note: Removing and installing the battery pack during suspend mode should be done within 1 minute. If the system does not resume after a charged battery pack is installed, replace the DC/DC card. If replacing the DC/DC card does not resolve the problem, replace the system board. 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. If a numeric code indicates the system board or the CPU card as a failing FRU, or the CPU card is indicated 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 528. Note: Don't touch the keyboard and pointing device when the system board test is running. This may cause an unexpected error. 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 this procedure does not correct the problem, go to "Undetermined Problems" on page 561. TrackPoint Checkout If the TrackPoint does not work, check the configuration in the ThinkPad Configuration program. If the configuration of the TrackPoint is disabled, select Enable to enable it. If this does not correct the TrackPoint problem, continue with the following. The TrackPoint automatically compensates to adjust the pointer sensor. During this process, the pointer moves on 538 IBM Mobile Systems HMM
