It sounds like you are experiencing issues with specific key combinations on your Surface Laptop 7. The behavior you described, where pressing Shift + @ results in typing " and Shift + hash not functioning as expected, could be related to keyboard layout settings or a potential hardware issue.
Here are some steps you can take to troubleshoot:
- Check Keyboard Layout: Ensure that your keyboard layout is set correctly for your region. You can switch between installed keyboard layouts by pressing the Windows logo key + Spacebar, or selecting them from the system tray.
- Update Drivers: Make sure your OEM drivers are up to date. You can check for updates in Settings > Windows Update.
- Test in Different Applications: Try using the keys in different applications to see if the issue persists across all programs.
- On-Screen Keyboard: You can also try using the On-Screen Keyboard (OSK) to see if the keys work there, which can help determine if it's a hardware issue.
- Feedback Submission: If the problem continues, consider submitting feedback through the Windows Feedback Hub, detailing the specific behavior and the applications where the issue occurs.
If the issue is hardware-related, you may need to contact Microsoft Support for further assistance or consider a warranty claim if applicable.
