Dell Statement Of Volatility User Guide
Summary
The Statement of Volatility for Dell Latitude E7240/E7440 documents the volatile and non-volatile components present on the system board. It details non-volatile components including embedded flash memory for BIOS code, panel EDID EEPROM, system BIOS flash, memory SPD EEPROM, RTC CMOS, and various other memory types. The document describes user accessibility for remedial actions and power state requirements for data retention. Target users are security professionals, auditors, and IT administrators responsible for data sanitization and hardware security compliance.

Statement of Volatility – Dell Latitude E7240/E7440 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Latitude E7240/E7440 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 E7240/E7440’s system board. Table 1.

Frequently Asked Questions
What state should I use if I want my system settings retained without losing all data?
Use the S4 'suspend to disk' (hibernate) mode, as the Operating System writes the context to non-volatile storage.
Which components on the board retain their data when primary power is lost?
Non-volatile (NV) components such as embedded flash and the RTC CMOS battery continue to retain user data even after power removal.
What is the difference between S3 and S4 sleep states?
S3 ('suspend to RAM') maintains dynamic RAM. S4 ('suspend to disk' or hibernate) saves context to non-volatile storage with no power.
If I remove the on-board coin cell battery, what data is lost?
Removing the secondary power source (coin-cell battery) destroys system data regarding the system configuration and time-of-day information.
