The Smart Connector is a magnetic port that allows you to connect compatible accessories, such as the Smart Keyboard or the Magic Keyboard, to your iPad. Sometimes, your iPad may stop responding to your keyboard or trackpad that’s connected with the Smart Connector. This could be due to various reasons, such as software issues, dirt or debris on the connectors, or interference from other cases or covers. According to the Apple Device Support Reference Materials1, the following steps can help you troubleshoot the problem:

Restart your iPad. This can resolve many software glitches that may prevent your iPad from recognizing your accessory. To restart your iPad, press and hold the Top button and either volume button until the power off slider appears. Drag the slider, then wait for 30 seconds for your device to turn off. To turn your device back on, press and hold the Top button until you see the Apple logo.

Remove any other iPad case or cover. Some cases or covers may interfere with the Smart Connector or the accessory’s magnets, causing connection issues. Make sure you remove any other case or cover from your iPad before attaching your accessory. Also, make sure the Smart Connector and the accessory’s connectors are clean and free of any dirt or debris. You can use a soft, lint-free cloth to gently wipe the connectors.

Update your iPad to the latest version of iPadOS. Updating your iPad can ensure that you have the latest features and bug fixes that may improve the compatibility and performance of your accessory. To update your iPad, go to Settings > General > Software Update and follow the onscreen instructions.
