Dell Precision 3541 - Statement of Volatility

Statement of Volatility – Dell Precision 3541 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Precision 3541 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 3541’s system board. Table 1.
