Hi Jimmie,
Thanks for posting your question here. I understand that the number pad on the right side of your keyboard does not work. This can happen if the Num Lock is turned off.
Please try pressing the Num Lock (NumLk) key once, or Fn + Num Lock on your keyboard. After that, try using the number pad again.
Let me know if you have questions, I'm here to help.
Thanks,
Jobelle C.
