Subject: Statement of Volatility – Dell OptiPlex 3050_MT
To whom it may concern:
The Dell OptiPlex 3050_MT 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 3050_MT motherboard:
