When the Copilot is plugged into a computer, the Copilot’s processor is in low power mode and is not in use. When you safely eject the Copilot and unplug it from your computer, it will ask to “Press Button” which allows the Copilot’s processor to determine how much free space and battery it has left, and then displays that information on the LCD screen. The Copilot will also ask you to Press Button after a reset.
Once you press the action button, the Copliot will scan for changes since it was last on and then be ready to use.
