If your Surface Pro 9 keyboard is not responding after trying to disconnect it, restart the device, and ensure it's updated, it may indicate a hardware issue, especially since the warranty has expired. Here are some troubleshooting steps you can try:
- Check Connections: Ensure that the keyboard is properly connected to the Surface Pro 9. Sometimes, a loose connection can cause it to stop responding.
- Test with Another Device: If possible, connect the keyboard to another Surface device to see if it works there. This can help determine if the issue is with the keyboard or the Surface itself.
- Update Drivers: Even if the system is updated, check if there are any specific driver updates for the keyboard. You can download drivers and firmware for your Surface from the Microsoft support site.
- Reset the Device: As a last resort, you may consider resetting your Surface Pro 9 to factory settings. Make sure to back up your data before doing this.
- Contact Support: Since the warranty is expired, consider contacting Microsoft support for further assistance or potential repair options.
If the keyboard is indeed malfunctioning and not responding, you may need to look into repair or replacement options as outlined in the Microsoft support documentation.
