Statement of Volatility - Dell LATITUDE 12 RUGGED EXTREME CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell LATITUDE 12 RUGGED EXTREME contains both volatile and non-volatile (NV) components. Volatile components lose their data 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 LATITUDE 12 RUGGED EXTREME system board. Table 1.
