Statement of Volatility – Dell Latitude E5250/5250
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell E5250/5250 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 E5250/5250 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 (DDR3, 1067 MHz).
Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration
and time-of-day information.
