Dell U2723QX Monitor Statement of Volatility
Summary
This technical guide defines component volatility for the Dell U2723QE/U2723QX display, crucial for advanced users and technicians. It details which internal components are non-volatile (retaining data when power is lost) versus those that are volatile. By identifying key chips like EEPROM and serial flash memories, this information prevents incorrect hardware handling and helps safeguard system configuration, firmware, and user data during maintenance or unexpected power loss incidents.

Statement of Volatility – Dell U2723QE/U2723QX CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell U2723QE/U2723QX 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 Dell U2723QE/U2723QX system board. Table 1.

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.

Frequently Asked Questions
What happens to user data when the main power cord is unplugged (Primary power loss)?
All volatile components, including DDR3 memory, will lose all user data immediately.
If I only remove the on-board coin-cell battery (Secondary power loss), what kind of data can be destroyed?
The system configuration and time-of-day information stored in secondary components are destroyed.
Which components retain their data even when power is removed?
Non-volatile (NV) components, such as Serial Flash and various EEPROM types, continue to hold data.
What does a CAUTION statement advise regarding hardware or data?
A CAUTION indicates a potential risk of damage to hardware or loss of data, and advises the user on how to avoid that problem.
