図3.2 Shutdown Method


When not using removable storage, it is possible to perform a shutdown by just disconnecting the power supply.

[警告]

Disconnecting the power supply while data is being written to removable storage may result in the filesystem or the data being damaged. Be sure to unmount removable storage first before disconnecting the power supply.
