Statement of Volatility – Dell Latitude 5430 Chromebook
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Latitude 5430 Chromebook 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 Dell Latitude 5430 Chromebook 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 (LPDDR5, 4800 MHz).
In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI power states the following is
provided (those ACPI power states are S0, S0iX , S4 and S5):
S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor.
