Surface Pro 4 type cover suddenly not working.

Hi E_C_H_O,

You can boot into the Surface UEFI to check if the Type Cover will be responsive. To boot into the UEFI, refer to this page. If it does not work in the UEFI, then it means that what you're having is a hardware problem. I would recommend that you take the device to a Microsoft Store or contact Microsoft Support for assistance.

If the Type Cover works in the UEFI, then the problem is related to the software. Please run the Surface Diagnostic Toolkit to check for any errors. To download the tool, open this link.

In case you need further assistance, please reply to this post.

Regards.

Type cover is still dead/unresponsive in UEFI. The Diagnostic tool found and did nothing. I also disagree with your assessment. A hardware problem implies something PHYSICALLY wrong. My SP4 hasn't left my dock in weeks. Also, without the correct drivers, the type cover is unable to communicate with the Surface. The reason I believe this is because I had a windows app that could execute commands by mutli-point touch and swipes. That app is also suddenly not working. 

I did a full windows reset last night and that did nothing. SO DO NOT DO A WINDOWS RESET TO FIX THIS PROBLEM!!!! DO NOT!! IT WILL NOT FIX YOUR PROBLEM!!! It will just add to your headache. This product has been nothing but a headache since the day I got it. 

Hardware issues can be physical damages or whole equipments/devices being faulty. Since the Surface did not recognize the Type Cover after performing a reset, let's check for physical connection issues. Try to disconnect the Type Cover and wipe the connectors using a clean, soft cloth. After doing that, reconnect it to the Surface. Do this 3 times and see if the Surface will recognize the Type Cover.

I'll be waiting for your update.

Dear Ruz_San,

There are dozen of people complaining about this issue and all you can suggest is to clean the connectors? How about you provide some evidence that Microsoft did actually something about this April windows update? I had no issues with my surface pro 4 device until the windows update. To date after hours spent fixing the problem, I still can't use the type cover . Yet every engineer is suggesting to wipe clean the connectors. What a joke!! 

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.

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.

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.

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.
