Statement of Volatility – Dell Precision 5560
The Dell Precision 5560 contains both volatile and non-volatile components. Volatile components lose their
data immediately after power is removed from the component. Non-volatile components continue to retain
their data even after power is removed from the component. The following Non-volatile components are
present on the Precision 5560 system board.
