Statement of Volatility – Dell Precision Mobile
Workstation M4800

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

The Dell Precision Mobile Workstation M4800 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 Mobile Workstation M4800 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.
