the last few days ive noticed that none of the 'F' keys are doing there functions printed, and my keyboard doesnt seem to light up anymore. Ive been looking around and all the threads say the same thing but nothing seems to be working for me. Ive reset pram and smc, checked and unchecked everythign i could in the keyboard settings under system prefrences... i just duno what to do anymore...i feel like they were working fine until the other day when i had head phones in, that may not be the actualy point i lost contact, but the last time i remember trying to use them and then them not working. again, i just dont know where to go with this anymore, running 10.6.6 2.4ghz 4gb ram... thanks for any help..
