Statement of Volatility – Dell Opti Plex 5090 Small Form Factor 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 5090 Small Form Factor 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 5090 Small Form Factor system board.

Frequently Asked Questions
What happens to data if the main power cord is unplugged?
Data on volatile components like DDR4 memory will be lost immediately. All user data on memory will be destroyed.
Does removing the coin cell battery erase configuration data?
Yes, removing the on-board coin cell battery destroys system data regarding configuration and time-of-day information.
Which power states does the OptiPlex 5090 Small Form Factor support?
It supports S0 (working), S1 (low wake-up latency), S3 (suspend to RAM), S4 (hibernate), and S5 (soft off).
Is system memory volatile or non-volatile?
System memory is volatile and loses data when power is removed, though non-volatile SPD EEPROM chips store timing info.
