The Dell Latitude E5430/E5530 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 Latitude E5430/E5530 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.
