Statement of Volatility – Dell U4320Q

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

The Dell U4320Q 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 U4320Q system board.

CAUTION: All other components on the system board lose data if power is removed from the system. Primary power
loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR3, 1067 MHz).
Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration
and time-of-day information.
