Keyboard problem

[Heath]

Hi, for some reason whenever I use some keys on my keyboard they come out with numbers. On the side of them they have numbers and that shows what they come out as. I can only type normally with this purple 'Fn' key whilst pressing it, like shift for a capital letter. I'm using a Sony VAIO Laptop. Any help with this appreciated as it takes me far too long to type otherwise.

They keys if you need to know them:

M = 0
J =1
K = 2
L = 3
U = 4
I = 5
O = 6
P = *
7, 8 and 9 have the same numbers underneath so they aren't causing a problem.
HELP! xD

Try turning Numlock off :D

Laptops replace other keys for the numpad when it's on, to save space :p
