Statement of Volatility – Dell Inspiron 15 3525 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell Inspiron 15 3525 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 Inspiron 15 3525 system board. Table 1.

Frequently Asked Questions
What is the difference between volatile and non-volatile components?
Volatile components lose data immediately after power is removed, while non-volatile components retain their data even when power is off.
What is the storage capacity of the SSD?
The system uses an M.2 - 2280 SSD drive in various GB sizes for non-volatile magnetic media.
What data is stored in the RTC CMOS memory?
The RTC CMOS memory stores CMOS information.
Is the system memory volatile?
Yes, the DDR4 memory is volatile and data is lost when the system is powered off.
Where is the Intel ME firmware stored?
The Intel ME firmware is stored in non-volatile memory combined on the BIOS for system configuration and security.
