battery will retain the data in the RAM for 30 minutes. When the backup battery is drained
out as well, the mobile computer will shut down, and only the contents of RTC will be
retained. All other unsaved data will be lost.
If you want to put away the mobile computer for a couple of days, you should be aware that
data loss occurs when the main battery and backup battery discharges completely.
Therefore, it is necessary to backup data and files before putting away the mobile computer.
