Your keyboard case has an LED light on the top right corner of the keyboard to indicate Bluetooth and battery status.

Power and battery

• Green, solid — sufficient battery level.
• Red, solid — battery is low. You should change your keyboard when you can.

Bluetooth

• White, quickly blinking — keyboard is in discovery mode, ready for pairing.
• White, slowly blinking — the keyboard is trying to reconnect with your Apple device.
• White, solid — pairing or connection is successful. The light then turns off to save energy.
