I don't know what happened. I turned my Surface Pro 4 on the other day and the type cover is dead. No lights. No response. No indication that it's working at all. I rarely take my surface anywhere.
This started on July 9th 2018. My system information is below. I've gone through all of the steps in the "Troubleshoot your Surface Type Cover or keyboard" page. I've tried to manually download and install the latest firmware and drivers from the "Download firmware and drivers for surface" page. I picked SurfacePro4_Win10_16299_1801701_1.msi. My device manager does not show the "Surface Touch Cover Filter Device" under keyboards or anywhere. It only shows the HID keyboard and cannot detect my type cover. The type cover is completely unresponsive. Also, my windows updates are completely up to date. I've provided the links to the troubleshooting pages I used below.

I called to Microsoft surface in Thailand, and they said the problem should be the hardware problem. So, they said I have to pay 450$(in approximately 16,000 baht) because mine was out of warranty. So, I decided to use wireless keyboard(Logitech MK240), it work fine for me. I think Microsoft should response for this problem. My surface pro 4 just 2 years, I use it a few hour, and the problem come after UEFI updating.
I have the same problem. In my opinion, the problem should come from firmware updating. I red the same problem, and the troubleshooting of this problem https://answers.microsoft.com/en-us/surface/forum/surfpro3-surfupdate/surface-pro-3-type-cover-not-working-in-biosuefi/b923c993-c055-4893-a834-04d077d02069 , but I still don't try it yet.
Having the exact same problem - happened after the last major update. A co-worker who went through the same issue a few months ago did a clean install which didn't solve the problem.
I spent the greater part of this last weekend doing the same useless troubleshooting (pressing power/volume buttons, system restore, system reset, uninstalling updates, re-installing drivers, cleaning connections).
Really disappointed, Microsoft. It would go an incredibly long way to at least announce/admit there is a widespread issue with Surface Pro keyboards being bricked by some software/firmware update. Knowing that a fix is possibly in the works would be encouraging to most folks. Staying silent on the issue will drive customers away.
Yup, you've nailed the current situation
>There is also no indication that Microsoft knows what the problem is or intends to fix the problem so the same thing could happen again.
You can also investigate 3rd party type covers that use Bluetooth like
https://www.amazon.com/Pinhen-Surface-Bluetooth-Detachable-Removable/dp/B01M3RLDFS
(one of these is for SP4, the others are for Surface 3). I have no firsthand
experience with these but Amazon has a good return policy.
So, I basically have a $150 useless cover and need to give Microsoft $450 because they broke my cover. There is also no indication that Microsoft knows what the problem is or intends to fix the problem so the same thing could happen again. I think I'm done with Microsoft hardware.
