Statement of Volatility - Dell Latitude 5430 Chromebook CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Latitude 5430 Chromebook contains both volatile and non-volatile components. Volatile components lose their data immediately after power is removed from the component. Non-volatile components continue to retain their data even after power is removed from the component. The following Non-volatile components are present on the Dell Latitude 5430 Chromebook system board. Table 1. List of Non-Volatile Components on System Board Description Reference Designator SSD drive(s) M.2 - 2230 Volatility Description Non-Volatile magnetic media, various sizes in GB. SSD (solid state flash drive). User Accessible for external data Yes Remedial Action (Action necessary to erase loss of data) Low level format System BIOS/EC Non-Volatile memory, Video BIOS for basic boot operation, PSA (on board U2501 (32 MB) diags), PXE diags. No U7103 Thunderbolt EEPROM LCD Panel EEDID EEPROM U7108 U7109 Part of panel assembly Non-Volatile memory, 8 Mbit (1 MB) (Thunderbolt FW) No Non-Volatile memory, Stores panel manufacturing information, display configuration data No System Four LPDDR5 Memory - memory down: LPDDR5 RAM 1/RAM Volatile memory in OFF state (see state memory 2/RAM 3/RAM 4 definitions later in text) No Non-Volatile memory 256 bytes RTC CMOS CPU1 (PCH) Stores CMOS information No Video Volatile memory in off state. memory - Using system Uses main system memory size allocated frame buffer memory out of main memory.

Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (LPDDR5, 4800 MHz). In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI power states the following is provided (those ACPI power states are S0, S0iX , S4 and S5): S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor.
