Dell Latitude 14 Rugged
Extreme (7404)
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Latitude 14 Rugged Extreme (7404) 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 14 Rugged Extreme (7404) system board.
