Hi Momoftwosins:

Numerical keypad usually require Num Lock to be ON.  The keyboard of my Inspiron 15 5584 laptop does not have an indicator light that shows if my Num Lock is on or off so when my numerical keypad stops working I've just gotten into the habit of pressing the Num Lock key once to turn the keypad on again.

As DELL-ChrisM2 requested, it would be helpful to know your Dell computer model.
