Statement of Volatility – Vostro 5502 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Vostro 5502 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 5502 system board. Table 1.

Frequently Asked Questions
Is all data lost if the system is unplugged?
No. Non-volatile components like SSDs, BIOS chips, and EEPROMs retain data even after power removal.
What should I do to prevent loss of data stored in non-volatile memory?
For attached external media (like flash drives), backup the data manually. For onboard chips, no action is specified to guarantee retention.
Are there volatile components on the Vostro 5502 system board?
Yes. Volatile memory includes DDR4 RAM and Video vRAM (VRAM1, VRAM2). All these lose their data immediately when power is removed.
What constitutes a 'primary power loss'?
Primary power loss is defined as unplugging the power cord and removing the battery. This destroys user data on the memory (DDR4).
