Statement of Volatility – Dell Latitude 3440
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Latitude 3440 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 Latitude 3440 system board.
