I noticed there are some hacks in the BF3 section that require a numpad to activate them and there have been multiple people asking how can they use numpad hacks on there laptop. It's quite simple and to reduce the amount of messages on the forum I'll go ahead and post this..
===================How it works:=======================
Simply put, you're able to use numpad commands, even if you don't have one implemented into your computer. Look around in your keyboard, and find a key called "FN" (Function).
Now, this'll work differently, depending on the laptop(s). Beneath the F keys, look for a really small icon similar to a regular numpad. It should be F8 or F11.
Did you find it? Now, hold FN and click the F8/F11 (or the correspondant key) and a little light should bright up, as if you were pressing CAPS LOCK.
There you go. It should be activated. Also, below the 789, UIOP, JKLP and M keys should be the respective key it enters when you press it. (for example, U equals 4, I equals 5 and O equals 6)
Look in the picture above if you can't find the numbers or if your laptop doesn't have them.
Anyway, you're good to go. If you want to turn these off to talk, do the same thing as you did to activate them; FN+F8/F11. Luckily, since FN isn't a stick key, you won't have to worry about getting messages popping up saying you're pressing them too fast.
You shouldn't, but just post here and I'll try to help as soon as I can.
Hope this helps all of you guys.
