Statement of Volatility – Dell C7520QT

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

problem.

The Dell C7520QT 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 C7520QT system board
