The touchscreen on your Surface Book should be automatically enabled. If it's not working, it might be disabled in Windows settings or there could be a hardware issue.
Here are some things you can try:
- Check the Windows settings:
- Go to Settings > Devices > Pen & Windows Ink.
- Make sure the "Enable touch input" option is turned on.
- Check the Surface Book's display settings:
- Right-click on your desktop and select Display settings.
- Ensure that the "Rotate" setting is set to "0 degrees".
- Restart your Surface Book:
- Sometimes a simple restart can resolve software glitches.
- Update your Surface Book drivers:
- Go to Settings > Update & Security > Windows Update.
- Check for and install any available updates.
- Check for physical damage:
- Inspect the touchscreen for any cracks or scratches.
- Make sure nothing is obstructing the touchscreen.
If none of these steps work, you might have a hardware issue. Contact Microsoft support for further assistance.
