Statement of Volatility – Dell OptiPlex 9010/7010
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the
problem.
The Dell OptiPlex 9010/7010 contains both “volatile” and “non-volatile” (NV) 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
9010/7010 motherboard:
