Sometimes, as I'm typing, suddenly [A] it ignores keys (it just did it now!) and I have to type them again, then it works, and [B] it sometimes repeats latest keystroke about 20 times.
Problem began a week or two ago.
Windows 10 Pro on DELL Precision 5530, which is 2 months old.
Problllllllllllllllllle <== this is an example of the problem, wwwwwwwwwwwwwwwwwwh (<==another!!!!!!!!!!!!!!!!! which keeps generating multiples keystrokes: ie: lll www and !!!)
Problem happens at home when laptop on dock station wired to keyboard, and at work when laptop on 2nd dock that has USB dongle to wireless keyboard.
DELL support checked drivers then 2 days ago came and replaced mother board. Problem still occurs.
