When I try to save any file my keyboard gives random outputs when naming. I have to use sticky notes to create the file name then cut and paste it into the save window. Here are some examples of the results of pressing each key 8 times.It only does this when saving a file. Everywhere else the keyboard functions normally.
We had the same issue precisely, we are not 100% sure what we did, but it was to do with Function NumLock... the NumLock was set to a weird setting. Now we fixed it we cannot break it again... but at least it is fixed.
