Dell OptiPlex 7000 Tower Statement of Volatility

Statement of Volatility – Dell Opti Plex 7000 Tower CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Opti Plex 7000 Tower contains both volatile and non-volatile components. Volatile components lose their data immediately after power is removed from the component. Non-volatile components continue to retain their data even after power is removed from the component. The following Non-volatile components are present on the Opti Plex 7000 Tower system board.
