Dell Precision 3240 Compact
The Dell Precision 3240 Compact contains both volatile and nonvolatile components. Volatile components lose their data
immediately after power is removed from the component. Nonvolatile components continue to retain their data even after
power is removed from the component. The following nonvolatile components are present on the Precision 3240 system board.

NOTE: All other components on the system board lose data if power is removed from the system. Primary power loss
(unplugging the power adapter) destroys all user data on the memory (DDR4, 2667 MHz). Secondary power loss (removing
the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information.
