10 key numeric pad

10 key numeric pad on fullsize keyboard is not working-tried 2 new keyboards & rebooting-but still does not function, any ideas?

 

Key pad boars, numeric key

Do not seam to work. This is my problem:

I can write numbers using the key board numbers key line, but I can not do it using the numeric Key pad integrated in the key board.

I have the same problem in four different Laptops. The numeric key pads is not working,
only to write number. It does work for arrow left & wright ect. The four Laptops are, Levono, HP, Surface 3 (External Numeric Key Pad) and the brand new Dell,

This is the problem:

I just purchase the new DELL laptop and when it finish loading everything and took my safety photo, and I write my PIN using the numeric key pad, everything work fine. then I receive a computer message at the screen "One Windows update is waiting".
I punch to install the update and after it finish is when I have the problem. It is not the numeric key, not external software installed by me, because I did not install any. I think that it has to do with the Windows update. The new DELL Laptop is now
at the Geed Squat of Best Buy. The will return it next Wednesday.

Thanks.
