Dell OptiPlex 7080 Micro - Statement of Volatility

Statement of Volatility – Dell Opti Plex 7080 MFF CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Opti Plex 7080 MFF contains both volatile and non-volatile components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. The following volatile and NV components are present on the Dell Opti Plex 7080 MFF motherboard: List of Non-Volatile Components on System Board

CAUTION: All other components on the motherboard will lose data once power is removed from the system. Primary power loss (Unplug the power cord and remove the battery) will destroy all user data on the memory (DDR4, CML-S (2666MHz), (2933MHz)). Secondary power loss (removing the on board coin cell battery) will destroy system data on the system configuration and time-of-day information.
