Hi Mahmudul Hasan Milhan,
Thank you for posting in Microsoft Community.
I am aware that you're experiencing issues with your Surface Book 2 keyboard where in some of the keys are not working intermittently. I am here to help and let us work on this together.
This could be caused by a number of factors, including hardware or software issues. Here are a few troubleshooting steps you can try:
- Restart your Surface Book 2: Sometimes, simply restarting your device can resolve the issue.
- Check for updates: Make sure your Surface Book 2 is up to date with the latest software updates. Go to Settings > Update & Security > Windows Update to check for updates.
- Run the Surface Diagnostic Toolkit: This tool can help identify and resolve issues with your Surface Book 2. See Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com).
- Detach and reattach the Keyboard.
- Unplug your Surface and detach the keyboard.
- Make sure there's no debris, damage or anything that may inhibit a connection.
- Re-attach the Cover, making sure that all the magnets touch the bottom edge of your Surface.
- Clean the keyboard: Dirt and debris can sometimes cause keys to stick or not work properly. Use a can of compressed air or a soft, dry cloth to clean the keyboard.
- Confirm connectivity. Press the Caps and Fn keys on your Surface Keyboard several times to check whether the LED lights turn on.
- If the LED lights turn on, your problem may be with Windows and not the device itself. The next step is to reset your Surface. Here's how:

- Select Reset this PC > Keep my files > Cloud download and follow the rest of the prompts shown on screen. For more detailed steps and a video, see Restore or reset Surface for Windows - Microsoft Support.
