I have a Surface RT with keypad. For a few weeks the keypad started inputting really slowly. I would type in and then letters would slowly be put in one by one after I took my hand on the keypad. Then it got to a point where it didn't work at all so I did the reinstall or whatever it's called. Then the keypad worked fine. As I went through to put in the numerous required updates (it takes 2 or 3 or so restarts and then check now's for new updates) the keypad would start after some updates and then not after others. Finally after a third (?) check now and install updates (and I did this all the way through twice with the same result) the tablet would automatically undo updates because they didn't work. What do I do? Thanks in advance!
