For a new Surface Laptop keyboard that intermittently misses letters, use this sequence to separate a Windows issue from a hardware issue:
- Check for updates Go to Start > Settings > Update & Security > Windows Update and install all available updates.
- Check in the Surface app
Open the Surface app.
- Expand Help & support to check update status.
- If updates are available, select Check for updates.
- Select Get help and describe the keyboard problem.
- Force a restart
- Select Start > Power > Shut down.
- After it turns off, press and hold the power button for 20 seconds.
- Keep holding even if the logo appears, until it appears again.
- Check for accessibility settings that can affect typing
Missed or ignored keystrokes can be caused by keyboard settings.
- Windows 11: Settings > Accessibility > Keyboard
- Windows 10: Settings > Ease of Access > Keyboard Turn Sticky Keys, Filter Keys, or similar keyboard options on or off as needed.
- Check for debris or a sticking key If one key is repeating or not responding, inspect the keyboard for foreign material. Use compressed air to clear dust and debris from the surface and between keys.
- Test outside Windows in UEFI
This is the key check.
- Turn off the Surface and wait 10 seconds.
- Press and hold Volume Up, then press and release Power.
- Keep holding Volume Up until the UEFI screen appears.
- Test the keyboard there.
- If the keyboard works correctly in UEFI but not in Windows, the issue is likely software-related.
- If the keyboard also fails in UEFI, that indicates a hardware problem.
- If it works in UEFI but fails in Windows
Reset Windows while keeping personal files:
- Go to Start, type reset, then select Reset this PC.
- Select Keep my files > Cloud download.
- If it fails in UEFI or keeps returning after troubleshooting On a brand new device, that points to likely hardware failure and the next step is to submit a service order.
