Statement of Volatility – Dell Latitude 7290 Owner's Manual
Summary
Statement of volatility for the Dell Latitude 7x90 series laptop family (7290, 7390, 7490), documenting all volatile and non-volatile memory components. Non-volatile items include M.2-2280/2230 SSD storage, 128Mbit System BIOS UC5 with Intel ME and ISH firmware, 64KB embedded controller boot ROM (MEC5105), Alpine Ridge NVM flash UT2, USB Type-C PD firmware UT6, LCD Panel EEDID EEPROM, and 256-byte RTC CMOS. The 7290/7390 use DDR4 via single SODIMM (4-16GB); the 7490 uses dual SODIMMs.

Statement of Volatility – Dell Latitude 7290 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Latitude 7x90 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 7x90 system board. Table 1.

Frequently Asked Questions
What happens if I lose primary power by unplugging the unit?
Primary power loss destroys all user data stored on the DDR4 memory.
Which internal components retain their data when the system is powered off?
Non-volatile (NV) components, such as SSD M.2 and BIOS, continue to retain data.
What information is lost if only the coin-cell battery is removed?
Secondary power loss destroys system configuration and time-of-day information.
