My numeric keypad in my dell G3 laptop is working in a different way suddenly..
For example the enter key write 97 instead of moving to next line..
The 7 botton writes 9 instead of 7
The 1 botton writes 100
The dot. Botton write a complete equation!
If the problem does not appear with an external keyboard, then there is a physical problem with the keyboard and it needs to be replaced.
