Statement of Volatility – Dell E2222HS 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 E2222HS 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 E2222HS 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.

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.
