Dell Statement of Volatility – Dell Latitude 7390 2-in-1 Owner's Manual
Summary
Statement of volatility for the Dell Latitude 7390 2-in-1 convertible laptop documenting all volatile and non-volatile memory components on the system board. Non-volatile items include M.2-2280 SSD storage, 128Mbit System BIOS/ME Firmware (UC5), 64KB embedded controller boot ROM (MEC5105), 8Mbit USB Type-C PD firmware (UT6), 8Mbit Alpine Ridge Thunderbolt NVM (UT2), LCD Panel EEDID EEPROM, and 256-byte RTC CMOS. LPDDR3 system memory (four on-board packages, 4-16GB) is volatile on power removal.

Statement of Volatility – Dell Latitude 7390 2in1 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Latitude 7390 2in1 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 Latitude 7390 2in1 system board. Table 1.

Frequently Asked Questions
What data type is lost if I physically pull the power cord?
All user data stored on the main memory (LPDDR3) will be destroyed due to primary power loss.
Which component stores basic boot operation information?
The System BIOS, ME Firmware BIOS, and Video BIOS store the necessary data for basic boot operations.
What is required to prevent data loss from the SSD drive(s)?
A low level format of the M.2 SSD media must be performed.
Which power state is categorized as 'hibernate' or suspend to disk?
S4 is the 'suspend to disk' state, where there is no power and the OS saves system context to a non-volatile storage file.
