Statement of Volatility – Dell Latitude 3450
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Latitude 3450 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 3440
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 (DDR3L, 1600 MHz). Secondary power
loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information.
