Frequently Asked Questions
What components on the Vostro 5402 are non-volatile?
Non-volatile components like the SSD drive(s), System BIOS, Thunderbolt firmware, USB Type-C PD firmware, and the RTC CMOS battery retain data after power is removed.
How do I prevent data loss from volatile memory?
To prevent loss from volatile memory like DDR4 RAM and Video memory, ensure you power off the system before removing power or the battery.
Does removing the power cord destroy all data?
Yes, primary power loss (unplugging the cord and removing the battery) destroys all user data on the memory components.
What happens if I remove the on-board coin-cell battery?
Secondary power loss, such as removing the coin-cell battery, destroys system data regarding configuration and time-of-day information.
