When did this start?
we don't know that you've tried "all" the fixes unless you tell us what you've
tried. have you tried your type cover on a friend or co-workers Surface and vice
versa? what version of Windows are you running and how did you roll back? did
you try a reimage from a downloadable recovery image
?
if you tried a different type cover AND a recovery image, then you likely need
an exchange.
>>I've searched online and tried all the 'fixes' but none work
I'm from Brazil and I'm suspicious to say that the problem is not just me. I have 2 Thpe Cover covers and none of them are working. Impossible. I tried many alternatives and none works. From trying to reinstall Windows one hour worked, but the next day was no longer working. In other words, this is not a problem on the keyboard. When I try to connect by pressing the button it goes into Bios, different from Microsoft's method. Not only I but users with the same methods enter the bios. Very strange.
