Constant Attaching/Detaching of Keyboard and tried obvious solutions

It's also possible that it's a hardware failure.

Firstly check out the Microsoft tutorials on Fix problems detaching or attaching your Surface Book keyboard.

Hi Doug, this was a great breakdown of the issue. I am having the exact same issue, even having trouble just typing this response. I did want to share one thing that seemed to help for a time. If you go into task manager, stop the Surface DTX Service. Good luck, hope we both find a more permanent solution.

I had this very annoying problem and just accidentally fixed it.

I was trying to clean the slots on the underside of the screen and I popped off the plate that surrounds them. I noticed that there was crud under the plate so I cleaned it out and, low and behold, 2 tiny magnets appeared under the crud.

After cleaning them I put the plate back on and the problem is totally gone.

Apparently the surfacebook uses those magnets to know its attached and if enough crud gets in the way they stop working reliably.

I don’t know everything I tried…. ha.

I actually just went out and got a Bluetooth keyboard and when I hooked it up the disconnecting problem went away. I picked up an small Anker brand at Walmart. I have uninstalled it and installed it a couple of times when the problem came back after updates. I am glad I didn’t return it after everything started working again. Knock on wood it keeps fixing the problem. I don’t think I will update for awhile to keep the magic going. Good luck.

Hi Doug. I am having this exact same issue. In frustration, I stopped using my SB for about 3 weeks. When I turned it back on, the problem had disappeared. Unfortunately, after 2 days, it returned. I have tried every proposed fix I could find online, but nothing has worked. Did you ever find a permanent solution? Thanks, Sean.

I have been having the same issue. Typing also triggers the detachment. The light turns green and my processes freeze. Also my five and six keys do not work along with my tab key. I have tried everything above. This is the second surface book (I have the OG surface book) and I had to return it. I really don’t want to keep starting over on a whole new hard drive. Also, with no stores I have to mail it in and pray it comes back in a timely manner. I can’t be without my device for long. I run my business from it. Ugh. Best of luck to you all.

Mine plainly came back to good working order on its own. Guys, it's so weird! I sent mine to post-warranty and they returned it saying that the fluid marker was activated and that they could only replace the whole Dock board for around 1800 euros. I told them to return it to me because other than maybe vapour or condensation there was no fluid contact with the laptop and that their solution is absurd! I changed my laptop from SB2 to another because I couldn't work like that (i.e. with an external keyboard) and after a year on the shelf, when a friend asked if he could use it as a desktop replacement at home, we just figured it worked just as before (this after all the updates - many - were made)… so, my SB2 works great now!

Using rubbing alcohol to clean the pins on the connectors helps. This was the last thing I tried because the pins looked clean to me. It was surprsing that it worked. Use compressed air to clean the connectors on the display part if you have a can of it.

Hi.

I have exactly the same problem. I've done everything you discribe plus a total reset. Nthe error is still present..

It shows when i'm working with word or using file explorer.,

Did you find a solution on your side ?

I had this same exact issue, I tried everything above. However after more troubleshooting, mine was most certainly a hardware failure. Since if you held the screen just right it would work. I have added a guide of what I did to take apart the base if you have to replace the Dock Connector.
