Dell Latitude 5285 Statement of Volatility
Summary
Statement of volatility for the Dell Latitude 5285 2-in-1 detachable tablet, documenting all volatile and non-volatile memory components on the system board. Non-volatile items include M.2-2280 SSD storage, 128Mbit (16MB) System BIOS UH1 with PSA and PXE diagnostics, USB Type-C PD firmware U22, LCD Panel EEDID EEPROM, 256-byte RTC CMOS, Intel ME firmware, and Security Controller U1 (32 Mbit, up-sell USH). LPDDR3 system memory (four on-board packages, 4-16GB) is volatile on power removal.

Statement of Volatility – Dell Latitude 5285 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Latitude 5285 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 5285 system board. Table 1.

Frequently Asked Questions
What components lose data when power is fully removed?
Volatile components, like system LPDDR3 memory (RAM), lose data immediately.
Which types of data are stored on non-volatile components?
Non-volatile components store permanent operating system configurations, BIOS settings, and SSD data, even without power.
What is the impact of removing the main power cord or battery?
Primary power loss destroys all user data on the memory (LPDDR3) and can destroy data stored in other volatile parts.
How does data retention differ between S4 and S5 power states?
S4 ('hibernate') saves system context to non-volatile storage. S5 ('soft' off state) saves no context, requiring a full boot.
