Statement of Volatility
Dell U4924DW Monitor
Instructions
U4924DW UltraWide Curved Monitor
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The purpose of this document is to certify that Dell’s U4924DW monitor will not save, retain or reproduce a signal to any internal or external component after power has been removed and reapplied to the unit.
The Dell U4924DW monitor contains both volatile and non-volatile (NV) memory ICs. Volatile memory(s) lose their data immediately upon removal of power. Non-volatile memory ICs continue to retain their data even after the power has been removed. However, no input video data is written into these memory ICs during operation.
Table 1. List of Non-Volatile Components on System Board
| Description | Reference Designator | Volatility Description | User Accessible for external data | Remedial Action (action necessary to erase data) |
| System EEPROM: | U22 | Non-Volatile memory, 256 Kbit for Storage of system setting (OSD) | No | NA |
| HDMI EDID EEPROM: | U10; U5 | Non-Volatile memory, 2 Kbit for Storage of HDMI EDID | No | NA |
| System Flash: | U4 | Non-Volatile memory, 128 Mbit for Storage of system firmware | No | NA |
| PD Controller Flash: | U332 | Non-Volatile memory, 8 Mbit for Storage of PD Controller firmware | No | NA |
| USB HUB Flash: | U321; U322 U323 | Non-Volatile memory, 4 Mbit for Storage of USB HUB firmware | No | NA |
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 onboard coin-cell battery) destroys system data on the system configuration and time-of-day information.
