Try these steps in order:
- Check keyboard language and input settings.
- Go to Start > Settings > Time & language > Region & language.
- Make sure the keyboard input language matches the display language.
- If they do not match, change them so they match.
- Check Windows keyboard accessibility settings.
- Go to Start > Settings > Ease of Access > Keyboard.
- Review settings such as Sticky Keys, Toggle Keys, and Filter Keys.
- If any are turned on, test with them turned off.
- If needed, turn on the On-Screen Keyboard with Windows key + Ctrl + O and test whether
.behaves normally there.
- Check for Windows updates.
- Go to Start > Settings > Update & Security > Windows Update.
- Install available updates.
- This is important because special key problems can happen when the PC does not have the latest updates.
- Reinstall the keyboard device.
- Open Device Manager.
- Expand Keyboards.
- Right-click the keyboard and select Uninstall.
- Restart the PC.
- Test whether the issue is likely hardware-related.
- If the same wrong key behavior happens even with the built-in keyboard consistently, and software settings do not fix it, the issue can be hardware-related.
- Similar cases in Microsoft Q&A indicate unusual key remapping or repeated wrong inputs are often caused by keyboard hardware problems.
- If the problem continues, get support.
- Open Get Help or use the Surface app support flow if available on the device.
- If the laptop was recently serviced or repaired, report it to the repair provider because keyboard issues that continue after software checks can be caused by hardware faults.
- Troubleshoot problems with your Surface mouse or keyboard
- Make your mouse, keyboard, and other input devices easier to use
