Statement of Volatility – Dell Latitude 7280/7480
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Latitude 7280/7480 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
7280/7480 system board.
