CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Latitude 5320 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 Latitude 5320 system board.
