If your click won't turn on
If nothing happens when you press the button, the battery is probably empty. Plug your click into USB and let it charge.
It may take up to 30 minutes before the screen turns on. A fully drained battery may need longer before the click works without the USB cable.
Your click cannot open Wi-Fi settings or sync when the battery is too low. Keep it plugged in and try again. The screen will tell you when USB power is needed.
