Statement of Volatility – Dell Vostro 3420 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Vostro 3420 contains both volatile and non-volatile components. Volatile components lose their data immediately after power is removed from the component. Non-volatile components continue to retain their data even after power is removed from the component. The following Non-volatile components are present on the Vostro 3420 system board. Table 1.

Frequently Asked Questions
Does the core system memory (DDR4) lose data when I power down the Vostro 3420?
Yes, DDR4 memory is volatile, meaning it loses its data immediately after the power is removed from the component.
Which components retain critical information even if the power is cut off?
Non-volatile units like SSD drives, BIOS/EC, CMOS, and Intel ME firmware retain their data even without main system power.
If using UMA mode for video, what cautionary step must I follow regarding power cycling?
If the UMA uses main system memory for the frame buffer, you must not power off the system to prevent potential data loss.
