Dell E7270 and E7470 - SOV Owner's Manual
Summary
Statement of Volatility for Dell Latitude E7270/E7470 documents volatile and non-volatile memory components on the system board for security compliance. It identifies NV components including embedded controller flash (288KB), system BIOS flash (128MB), panel EEPROM (128 bytes), memory SPD EEPROM (512 bytes), and CMOS BBRAM (256 bytes), with remedial actions to prevent data retention. For security officers and compliance auditors managing data sanitization of these Latitude laptops.

Statement of Volatility – Dell E7270/E7470 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell E7270/E7470 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 E7270/E7470’s system board. Table 1.

Frequently Asked Questions
What types of components store data on the E7270/E7470?
The system contains both volatile components (which lose data immediately when power is removed) and non-volatile (NV) components.
If I lose primary power by unplugging the cord, what data will be lost?
All user data on the memory (DDR4, 1866/2133 MHz) will be destroyed.
What is the permissible range for system memory installed?
System memory size must be between 2 GB and 16 GB.
How does S3 state differ from S4 (hibernate) mode?
S3 'suspend to RAM' maintains dynamic RAM. S4 writes the system context to non-volatile storage file since there is no active power.
