Statement of Volatility – Dell Vostro 3520 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Vostro 3520 contains both volatile and non-volatile components. Volatile components lose 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 Vostro 3520 system board. Table 1.

Frequently Asked Questions
What happens to volatile components when power is removed?
Volatile components lose their data immediately after power is removed from the component.
Which types of memory are considered non-volatile on the Vostro 3520?
Non-volatile types include SSD drives, Video BIOS, PSA (on board BIOS/EC), EEPROM, and CMOS RTC.
Are all system memories volatile?
No, some components like flash storage (SSD) and the RTC CMOS retain data even when power is removed.
What type of memory is used for the main system memory slots?
The system uses two DIMM DDR4 slots, which are classified as volatile memory in the OFF state.
