Dell Latitude E7240 Manual

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.
