Then I tried something not mentioned anywhere else and it worked. i literally worked an entire day with just the touch screen and was furious. Tried this and EVERY OTHER guide on how to fix this issue and none of them worked. My new Windows 10 book, find out more here. Here is a video of how to fix it and if you like this tip please checkout my new Windows 10 book. If parts of your keyboard are working then you should checkout my other solution. This worked for me and hopefully it will work for you. When you come to your Surface Pro 3 or Surface Pro 4 and the keyboard and trackpad do not work at all here is a quick fix. I have come across another problem with the Surface Pro keyboard that causes it to not work at all looking like a major hardware issue but there is a surprisingly easy fix.
A couple of years ago I wrote about how to fix keyboard problems with the original Surface RT and it remains a popular post on the site.
