Typing alt codes on my laptop..?

[WolfA]

Ok so I have an HP Pavilion G6 laptop, it has the function (fn) key but the keyboard lacks a numlock, scroll lock and the number pad. The fn key is white like other keys and there are blue letters but no blue number letters are evident under any key. I want to be able to type alt codes with this keyboard, I do not want to use the on screen keyboard. Can anyone tell me how or if it is even possible using the physical keyboard?

@soupfine doesn't work, there are no numbers under the 789uiojklm keys which I am aware that they are there on most laptop keyboards.. but not mine

Yes...to type an alt code you press the fn key..hold it down and then press the key that also doubles as a numeric keypad key. Look closely at your keyboard...on my keyboard the J key is also the numeric key 1. The K key is also numeric 2 and so on.

Anyway, to type alt codes you hold down the fn key and then press the appropriate letter key that also doubles as a numeric keypad key.

EDIT

I looked up your keyboard and it looks you are out of luck...there seems to be no option for the numeric keys on that keyboard and others have complained about that also.
