Statement of Volatility – Dell Chromebook 3100
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Chromebook 3100 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 Chromebook 3100 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 (LPDDR4, 2400 MHz). Secondary power loss (removing the on-
board coin-cell battery) destroys system data on the system configuration and time-of-day information.
