Statement of Volatility – Dell Precision T1700

CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.

The Dell Precision T1700 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 Dell Precision T1700’s
system board.
