

CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the

problem.

The Dell Precision M2800 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 Precision 2800 system board.
