Dell U4320Q Statement of Volatlity - Page 1

Statement of Volatility - Dell U4320Q CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell U4320Q 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 U4320Q system board. Table 1. List of Non-Volatile Components on System Board Description Reference Designator Volatility Description User Accessibl e for external data Remedial Action (Action necessary to prevent loss of data) IC FLASH MX25L6433 FM2J-08G SOP 8P U301 Non-volatile Flash memory, No 64M bit. To store firmware. IC FLASH MX25L8006 EM1I-12G SOP 8P U1308 Non-volatile Flash memory, No 8M bit. To store PD firmware.

Part place on Interface Board, it has hardware write protected. Part place on Interface Board, 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 (DDR3, 1067 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information. Nov 2019
