Step-by-Step Fix

Turn Off Num Lock
On small laptops, Num Lock turns part of the keyboard into a number pad.
2
Check Language Settings
Ensure the layout is set to "US English" (or your local language).

Test with On-Screen Keyboard
If OS keyboard works, the physical keyboard is faulty.
When to See a Technician
