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.
