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.
