You are troubleshooting a laptop where the user has reported log in problems. The user states
that her password does not work on the laptop, but it is working on other computers in the domain.
When you try to log in you observe that numbers have appeared in the place of certain letters in
your username. Which of the following is MOST likely the cause of the problem?

A.
The computer has a key map for another language installed.

B.
The number lock function is turned on.

C.
The keyboard has been damaged by force or someone has had some kind of liquids in the
keyboard.

D.
The scroll lock function is turned on.

Explanation:
Laptop keyboards do not have a numeric keyboard on the side, instead they change the function
of some of the letter keys into number keys when numlock is activated.
