Statement of Volatility – Dell OptiPlex 3020M
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell OptiPlex 3020M contains both volatile and non-volatile (NV) components.
Volatile components lose
their data immediately upon removal of power from the component.
Non-volatile components continue to
retain their data even after the power has been removed from the component. The following volatile and NV
components are present on the Dell OptiPlex 3020M motherboard:
