Today I contacted Apple Support and they’re sending me a replacement keyboard. However, the doubt between whether it is a hardware or software problem continues and I’m fairly sure that there are issues with BOTH, which will be confusing Apple in trying to work out a fix.
Why am I so sure? Well, after my contact with Apple Support this afternoon, I was thinking a bit more about something I told them ... which is, that I had noticed that the 3 contacts on the keyboard are not level, whereas the contact points on the iPad appear to be perfectly aligned/level. So that could be a manufacturing error which causes the problem ... although I have no way of knowing whether it is normal or not.
Anyway ... aside from that.
Normally I get my keyboard to work, by rocking the iPad forward, until it’s almost flat/parallel with the keyboard, then rocking it back into its normal position. Usually this works at first attempt and I can use the keyboard, although sometimes it can take several goes to get it to ‘stick’, so that it remains connected and the software keyboard is not visible.
This evening I had a thought ... what if the iPad just needs to be more vertical? So, I placed a 1cm high object underneath the ‘triangle’ at the back of the iPad. IOW, that part of the keyboard that is folded into a triangle. So now it is raised up about 1cm at the back. I have found that I can now move/slide the ensemble on my desk and the keyboard remains connected.
So this tells me that it is indeed, in my case, a hardware issue. I do think though, that there is perhaps a software issue too.
