Hi... For some reason my Surface 4's cover keyboard/touch pad mouse has suddenly stopped working. It works OK when I access the UFEI so my thinking is that it's a software issue. I have: deleted and then re-installed all the keyboard drivers, Disabled and then re-enabled keyboard functionality in UFEI, checked all drivers are up to date, Force shut down'd the Surface Pro and then restarted it I have even tried disconnecting the surface cover keyboard overnight and reinstalling it the next morning The only thing left seems to be a full reinstall of Win10.... But before I do that I was winding if anyone else has had a similar problem and knows of a fix. Thanks in advance.
