Frequently Asked Questions
Which components on the Dell Latitude 7x90 retain data after power is removed?
Non-volatile components like SSDs, System BIOS, Intel ME firmware, and embedded controllers retain data even after power is removed.
What happens to data if the main power cord is unplugged?
All user data on volatile components, such as the DDR4 system memory, will be destroyed.
Does removing the coin-cell battery affect system configuration?
Yes, secondary power loss from removing the coin-cell battery destroys system configuration and time-of-day information.
