Statement of Volatility – Dell Latitude 3320
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Latitude 3320 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 3320 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 (DDR4, 2667 MHz). Secondary power loss (removing the on-
board coin-cell battery) destroys system data on the system configuration and time-of-day information.
