CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the

immediately after power is removed from the component. Non-volatile (NV) components continue to retain their data even

after power is removed from the component. The following NV components are present on the OptiPlex 3020 system board.
