why have so many people had trouble with their type covers since mid 2017? Mine pefectly OK one day - totally dead the next! It is not detected in device manager. My SP3 is now junk as a work tool. Update history says keyboard driver 1.1.504.0 successfully installed on25th of August. Microsoft obviously not taking notice of this forum, can someone please get them to look at this problem. People have tried to attach new keyboards but they don't work either so the keyboard is not the problem. *** found on internet: Microsoft today issued a big set of firmware updates for Surface Pro 3, all of which are related to supporting the new Surface Pro Type Cover and Surface Pro Signature Type Cover.
