The Dell Latitude 7x90 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 7x90
system board.
