Statement of Volatility – Dell P3510
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell P3510 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 P3510’s system board.
