Statement of Volatility – Dell Opti Plex 5000 Tower CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Opti Plex 5000 Tower 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 Opti Plex 5000 Tower system board.

Frequently Asked Questions
What types of power loss destroy all user data on the memory?
Primary power loss (unplugging the power cord or removing the battery) will destroy all user data on the DDR4 memory.
How is "suspend to RAM" mode defined regarding power?
S3 state maintains dynamic RAM. It requires that both the OS and peripherals support this state.
Which components retain their data after power is removed?
Non-volatile components like hard drives, M.2 SSDs, and embedded flash retain data even if power is disconnected.
What does removing the on-board coin cell battery affect?
Removing the coin cell (BT1) will destroy system configurational and time-of-day information stored in the CMOS memory.
