The Dell diagnostics (F12 at powerup) includes a keyboard test - run that.

Hi,
Welcome to the Community. Does this happen with only a certain application or anywhere. Click on start, run, type in cmd and press enter, try using the underscore key in the black box to check if it works.
Thank you

There is something wrong with the keyboard or the interface if an external USB keyboard does not do the same thing.
Has there been any liquid spilled into the laptop?
