You are working as a technician at Certkiller .com. You are asked to troubleshoot a laptop that
when typing letters on the keyboard, seemingly randomly prints some letters and some numbers.
What is the most probable cause of this?

A.
Number Lock is on.

B.
Function Key is on.

C.
sticky keys have been activated.

D.
number key is stuck.

Explanation:
As a laptop doesn’t have a numeric keypad the numlock key will activate a “virtual” numeric
keypad on top of the normal letter keys.
