My Surface Pro 4 Keyboard with Touch is no longer being recognized by my Surface Pro 3 after updating to 1803.
I have disconnected and reconnected dozens of times.
I have cleaned my connectors on both the Surface Pro and the Keyboard unit.
I have uninstalled the keyboard in Device Manager, as well as the mouse however the only things showing up there are HID compliant Mouse and Keyboard, nothing that says Surface or Type Cover.
I have hard reset the device several times (Volume Up and Power), also booting into UEFI/BIOS several times where the keyboard also does not work.
I registered my device with Microsoft to of course be told it is Out of Warranty.
I am in the process of downloading the Recovery Image from 2015 from a trustable 3rd party website since I cannot find any links to the recovery image on Microsoft's website. This will I think put me back in time to before the 1803 update as far as Windows is concerned, however I am not sure if that will fix my problem since it is not being recognized in the BIOS.
Any suggestions you have would be greatly appreciated.
