There are Several threads here on the Numpad problem. There is NO numlock, it is a dedicated calculator key so there is no shifted state. This is ridiculous on a gaming computer, or ANY laptop. We need a MOD to put all these complaints and sticky it so it gets the proper attention and gets fixed asap. There is supposed to be a bios update in the works. When i purchased the G74SX i never figured i would need to check and see if the manufacturer had removed the NUMLOCK and shifted position of all the keys associated with it. Had i known this i would have purchased a different laptop. It wasn't until i first setup my system and went to assign keys in a game when i realized there was no Numlock and associated keying. Unfortunately that was after my 7 day return policy from Micro center. Now i am stuck with a faulty machine due to a serious design flaw from the manufacturer. This is not at all what i would expect from ASUS. I have been using their motherboards and video-cards in all the machines we build for our clients since ASUS started selling motherboards, and the only times i have had problems was with a world wide capacitor problem, where the capacitors were faulty.(not ASUS problem but a supplier problem) and the Intel chip-set problem from the original sandy bridge.(also not due to ASUS) so i would never figure them to do something like this when every other laptop, device or component has been done to industry standard or better. Hopefully they will fix this in a fast manner.
