Statement of Volatility – Dell OptiPlex 3080 Tower
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell OptiPlex 3080 Tower contains both volatile and non-volatile 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 3080 Tower motherboard:
