Dell E1715S Troubleshooting

Statement of Volatility – Dell E1715S

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

The Dell E1715S 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 E1715S 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, 1067MHz).
Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration
and time-of-day information.
