I have just bought a Acer laptop. The model, as it says on my laptop, Aspire 4752-6838. The problem is that my fn hotkeys do not work for raising and lowering the volume or muting or playing. That would be fn + up, fn + down, and fn + f8, respectively. Interestingly enough, my fn hotkeys work for other functions like num lock, brightness. Im not sure about my other fn keys working, but i dont have a need for them, so i dont care. However i really want to use my fn hotkeys for volume control. Is there any way to enable this? Or does any one know where this problem arises and a solution? BTW i read the manual and it doesn't help me with my problem. I also tried searching google and found no help either. If anyone knows where else i can look, that would help too.
