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.
