Statement of Volatility – Dell Latitude E7240/E7440
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell Latitude E7240/E7440 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 Latitude E7240/E7440's
system board.

Summary of Contents for Dell Latitude E7240
- Page 1 The Dell Latitude E7240/E7440 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 Latitude E7240/E7440’s system board.
- Page 2 When the system is coming back to the working state, a restore file from the non- volatile storage can occur. The restore file has to be valid. Dell systems will be able to go to S4 if the OS and the peripherals support S4 state.
