Statement of Volatility – Dell Precision M4700/M6700
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Precision M4700/M6700 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 Dell Precision
M4700/M6700 system board.
