Statement of Volatility – Dell U2721DE
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you
how to avoid the problem.
The Dell U2721DE 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 U2721DE 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.
