Dell U4025QW Monitor Statement of Volatility
⚠️ CAUTION: A CAUTION indicates either potential damage to hardware or erasure of data and tells you how to avoid the problem.
The U4025QW Monitor contains both volatile and non-volatile components. Volatile components erase 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 U4025QW Monitor system board.
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) |
|---|---|---|---|---|
| IC FLASH MX25L6433FM2J-08Q 64M SOP 8P | U301 | Non-volatile flash memory, 64 MB to store firmware. Delta-E and Uniformity calibration data. | No | Part place on Interface Board, it has hardware/software write protected. |
| IC EEPROM 64K*8 M242512-RMN6TP SO8 | U302 | Non-volatile memory, 512 KB to store Scaler data. | No | Part place on Interface Board, it has hardware/software write protected. |
| IC EEPROM M24C02-WMN6TP SOIC 8P | U1202 | Non-volatile memory, 2 KB to store HDMI EDID | No | Part place on Thunderbolt Board, it has hardware/software write protected. |
| IC FLASH M25V20066M1102 2M SOP 8P | U2902 | Non-volatile flash memory, 2 MB to store firmware. | No | Part place on Interface Board, it has hardware/software write protected. |
| IC FLASH W25X40CLSNIG 4M SOP 8P | U1906/U1914/ U1915/U1906 | Non-volatile flash memory, 4 MB to store firmware. | No | Part place on Interface Board, it has hardware/software write protected. |
| IC FLASH GD25Q16ESIGR 16M SOP 8P | U2601 | Non-volatile flash memory, 16 MB to store firmware. | No | Part place on Thunderbolt Board, it has hardware/software write protected. |
⚠️ CAUTION: All other components on the system board erase 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.
