In the Devices portion of the Control Panel no errors show up. It's just not registering any action on the keyboard. When closing or opening the cover I can see it hide and show on the setting screen. I can see it in the 'devices' section of the settings app but no keyboard light nor does any key-press work. Recently the keyboard cover stopped working. This report from JasonCliche seems particularly apropos: There are similar reports from Singapore, on Windows Central, and many, many more on the Microsoft Answers forum. Does anyone knows if there is a different way to reset drivers or to change HID Keyboard driver to Surface proper driver? Tried to 'reset' drivers by holding Volume up + Power button for 10 seconds but it has just took me to bios menu.

Tried to uninstall drivers and reinstall but still unsucessful. It appears in device manager as HID Keyboard but not Surface Cover. I have experiencing some trouble to setup my surface cover keyboard. On the Surfaceforums blog there’s a distressingly similar complaint about the Surface Pro 3. For some subset of Surface Pro 4 users (no doubt a “ small number” of customers), the keyboard doesn’t work, and Microsoft isn’t answering questions. Looking at the other complaints on that thread, it appears as if refreshing Windows doesn’t help at all. I do not wish to refresh windows as i don't want to have to reinstall everything, and i can't roll back the surface firmware updates. My type cover was attached throughout this process. … I have tried doing a restart, hard restart, uninstalling the existing keyboard drivers and clicking on scan for hardware changes, but the surface type cover filter device doesn't come back.

Poster kzh91 on the Microsoft Answers forum describes the problem:Īfter a recent surface pro 4 firmware update, my 'surface type cover filter device' driver disappeared, and my type cover no longer works. There are tantalizing hints that the bug arrived with a recent pushed software update, and it may affect some Surface Pro 3 machines as well. This time the symptoms involve a suddenly dead Type Cover, a missing driver - and no help from Microsoft. Yet another report of problems with the Microsoft Surface Pro 4.
