    MS Surface Book 3 - Keyboard works only in UEFI/Linux

    This is a very weird issue which I'm having trouble finding a common thread.

    The keyboard is registering keypresses in either the UEFI, or a live Linux USB environment - I used Ubuntu for testing. The keyboard backlight is lit.

    The keyboard is registering keypresses in Windows or any Windows-related bootable device. For example, it does not work in Hirens Recue or a Windows 11 bootable installer.

    When booted to Windows, not only is the keyboard not registering keypresses, but my USB keyboard is not either!

    USB mouse and integrated trackpad are both working regardless of software environment.

    Onscreen keyboard is working with touch. I don't see any firmware updates available. I have deleted all keyboard entries from Device Manager and restarted.


    Any thoughts on this?

    I resolved this by doing an in-place Windows repair installation.
