Windows 7 - How To Activate NumPad On ASUS G74SX-XT1???

Hi everyone , i just bought the ASUS model listed above and lately I've been playing Grand Theft Auto IV. I installed a trainer for cheats and such for the game, and it requires the use of the NumPad to navigate the trainer's menus within the game itself. But I cant find a key labelled "NumPad" anywhere on my keyboard, so now I'm stumped as to how to activate it. There must be some kind of function key or some other arcane key combo I have to press to activate it. But I've tried everything I know, nothing has worked. I decided not to post this question in the gaming section because I also have other apps besides GTAIV which also require use of the NumPad, so this is more of a generalized issue. This is a brand new laptop, not refurbished or anything like that. I've also read the manual for the laptop, but no help there. So, If anyone here has my exact laptop model and knows the answer to my question then please reply. Thanks!

I am sorry, but prepare to be disappointed.....There is no Num-pad Key or a way to activate it.

From what I have read, It works, but not in the way gamers need it to.
