Statement of Volatility – Dell WD19S/WD19DCS/WD19TBS CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell WD19S/WD19DCS/WD19TBS 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 WD19S/WD19DCS/WD19TBS system board.

prevent loss of data)
ED SPI ROM UE1 Non-Volatile memory 128kb Flash, Store EC No NA
program code to control GPIO & communication with TI PD via i2C interface
USB UI4, UI1 Non-Volatile memory 2 Mbit. Stores USB No NA Gen1/Gen2 Hub FW. Hib ROM UI4 for Gen2,
UI1 for Gen1
DP MST Hub UV1 Non-Volatile memory 4M bit. Stores DP No NA SPI ROM MST Hub FW.
Intel Titan U2 Non-Volatile memory 8M bit. Stores Intel No NA Ridge SPI Titan Ridge FW. ROM
CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR4, 2667 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information.

Frequently Asked Questions
Does the WD19S retain data if the power is cut?
No. Primary power loss destroys all user data on the DDR4 memory.
What components maintain their data after power removal?
SPI ROM, USB Hub ROMs, DP MST Hub ROM, and Intel Titan Ridge are non-volatile.
How does a 'CAUTION' in this manual impact the user?
It warns of potential damage to hardware or loss of data and specifies how to avoid it.
What is lost when only the on-board coin-cell battery is removed?
System configuration and time-of-day information are lost.
