Dell OptiPlex 9020 Manual

Statement of Volatility – Dell OptiPlex 9020
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell OptiPlex 9020 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 9020 motherboard:
