CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss
(unplugging the power cord and removing the battery) destroys all user data on the memory (DDR3, 1067 MHz). Secondary
power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day
information.
