Statement of Volatility – Dell OptiPlex 5080 MFF
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell OptiPlex 5080 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 OptiPlex 5080 MFF motherboard:

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.
