unplugging and unstable power connections. Despite having 10 minutes of power, the NAS shuts down
after 1 minute because this is a safety valve, and without a proper shutdown all the information in the
RAM cache would be erased and there could be permanent damage to your data. The purpose of this
battery is to prevent data loss.
