Gregory,
‘Your profile isn’t public so couldn’t find any other info.’ I did include - albeit via a slightly later edit - a link to the relevant thread. Here too is a link to another thread - one that surveys users asking whether they’ve had the same type of problem.
‘Just had one with the same, wondered if you’d tried to realign the keyboard in the input cover.’ I have not tried. For, apparently, the job involves very many screws, some of them fiddly and breakable.
