What to Do:
- Ensure that your console has the latest system version.
- If your console is already up to date, be sure to restart it by holding down the POWER Button for at least three seconds, then selecting Power Options followed by Restart.
- If you are unable to perform a system update due to the Joy-Con controllers not being recognised, you can use the touch screen to connect to the internet and enter the required fields.
- Detach the Joy-Con controllers from the console, and continue with the next steps by troubleshooting one controller at a time.
- Reset each Joy-Con by pressing the SYNC Button once. Then press any other button on the controller to power it on again.
- Attach the Joy-Con to the console, ensuring that it is correctly oriented and inserted all the way.
- If the Joy-Con is still not recognised by the console, try to detach and reattach it to the console a couple times.
- If at all possible, test another Joy-Con with the console.
