Dell OptiPlex 3050 All In One - Statement of Volatility
Summary
Understand how your Dell OptiPlex 3050 handles data during various power loss scenarios. This technical guide details the volatile and non-volatile components—including RAM, storage drives (SSD), and BIOS memory—and clarifies what information is retained or lost when the system transitions between power states (S0 through S5). Ideal for IT professionals, technicians, or advanced users who need precise knowledge about data continuity, proper shutdown procedures, and system configuration integrity.

Subject: Statement of Volatility – Dell Opti Plex 3050
To whom it may concern:
The Dell Opti Plex 3050 contains both “volatile” and “non-volatile” (NV) components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. The following volatile and NV components are present on the Dell Opti Plex 3050 motherboard:
Remedial Action
Description Reference (action necessary
Designator Volatility Description User Accessible for external data
to lose data)
System E56 Non Volatile memory, No N/A BIOS 128Mbit (16MB), System
BIOS and Video BIOS for basic boot operation, PSA (on board diags.)
EDP S1U2 8KB Non Volatile memory, No N/A EEPROM which stores FW
information for EDP IC.
System Connectors: DIMM1, Volatile memory in OFF No Power off system Memory – DIMM2 state (see state definitions N/A DDR4 DIMM later in text) memory One or two modules will be
populated. System memory size will depend on DIMM modules and will be between 4GB to 32GB.
RTC CMOS BATT1 Volatile Battery back- No Removing the on
backed CMOS memory 256 board Coin Cell bytes battery Stores CMOS information
TPM 1.2 U22 16KB non-volatile memory, No N/A
which stores FW information for TPM IC.
Hard drive/ User replaceable Non Volatile magnetic Yes Low level format SSD (M.2) J219 media, various sizes in GB

Frequently Asked Questions
How is CMOS information stored and protected?
CMOS information is stored in a volatile coin cell battery-backed component (RTC CMOS BATT1).
What types of data are lost upon primary power loss?
Primary power loss will destroy all user data on the memory (DDR4) and system components.
Can I store data when the unit is merely placed in stand-by mode (S3)?
Yes, S3 'suspend to RAM' state maintains the dynamic RAM, allowing system context retention if supported by OS/peripherals.
Which memory types are considered non-volatile?
Components such as System E56 and TPM 1.2 are designated as Non-Volatile (NV) memory, retaining data after power removal.
