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 Tablet-7202 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
12 Rugged Tablet-7202 system board.

CAUTION: All other components on the system board lose data if power is removed from the system. Primary power
loss (unplugging the power cord and removing the battery) destroys all user data on the memory (LPDDR3).
Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration
and time-of-day information.
