CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.

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 7390
2in1 system board.
