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. Table 1. List of Non-Volatile Components on System Board Description Reference Designator Volatility Description User Remedial Accessible for Action (action external data necessary Embedded Flash memory in embedded U38 controller MEC5075 256K and 2K byte of embedded Flash memory for embedded controller BIOS code, asset tag and No N/A BIOS passwords Non Volatile memory 64K bytes.
