Keyboard locked out after Windows 10 upgrade.

    Keyboard locked out after Windows 10 upgrade.


    Product Name: HP Spectre x360 - 13-4158ca
    Operating System: Microsoft Windows 10 (64-bit)

    1. I recently had to reinstall windows 10 on my laptop because of a failed ssd. I've managed to reinstall windows 10 using a bootable USB media.

    2. Install process and user setup using the keyboard was normal and un-eventful

    3. Device manager initially showed several question marks on some of the devices, but after re-installing the drivers from HP support website, all of these disappear.

    4. However on restart, the keyboard and the touchpad are disabled. I cannot make any entries via the keyboard or touchpad at all. I can only use the onscreen keyboard and mouse.

    5. Uninstalling the SYNAPTICS touchpad driver fixes the touchpad, but the problem with keyboard still remains.

    6. Device manager now shows 2 keyboards HID Compliant Keyboard and Standard PS/2 keyboard. I don't have any external keyboard or docking station connected.

    7. I know the physical keyboard works because the UEFI Hardware diagnostics shows functional keyboard AND I am able to make use of the keyboard while I enter the PC user data during the OS setup. UEFI Systems Extensive Test also does not report any failures.

    THE Question: Is there any setting that I need to change to get the keyboard to work or do I have to delete anything? I have tried to delete either or both of the keyboards reported by device manager but this doesn't seem to work.

    Any suggestions would be wellcome.

    Thanks.

    Hi moonbugs

    Any chance you enabled Tablet mode. Click or tap on the Notification icon, lower right, one of the squares is labelled Tablet.
