- Observe key response: Try pressing a few keys to see which ones register, which ones are unresponsive, or if the entire keyboard loses signal.
- Check the indicator lights on the keys. Inspect the Caps Lock, Num, or power lights. If the lights don't change when pressed, the keyboard may be disconnected.
