CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Latitude™
E6230/E6330/E6430/E6430ATG/E6530 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
Dell Latitude™
E6230/E6330/E6430/E6430ATG/E6530 system board.
