Statement of Volatility – Dell
Latitude 7320 and 7320 2-in-1
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Latitude 7320 and 7320 2-in-1 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 7320 and 7320 2-in-1 system board.
