[G4] numeric keypad not working

[H F]

Silly thought, but once upon a time such problems for me were often solved by unplugging the offending device/cable and just blowing any accumulated schmutz out. Have you tried tried this?

But that finally went away and hasn't been seen for a while. It had to be a problem with some fipflop that got set accidentally.
