Hi @jack lin
Thank you for reaching out to Microsoft Q&A Forum.
Based on your description, it seems like your keyboard is not working after powering on the device.
Here are a few basic steps you can try:
- Check if the keyboard is properly connected (wired or wireless).
- Try using another USB port or replacing the batteries if it’s a wireless keyboard.
- Restart your device and see if the keyboard responds.
- If available, try the keyboard on another device to rule out hardware issues.
If the keyboard is still unresponsive, you may want to contact your device manufacturer’s support for more specific troubleshooting.
I hope this helps!
