I have a basic wireless keyboard http://www.apple.com/ca/shop/product/MC1… and all of a sudden my top row of Function keys and the number one to nine numeric keys and their shift-symbols don’t work, nothing happens when I try to use them in any application. On the left of the number one, the `~ key works, and on the right the 0), -_, =+ keys work fine, as does the delete key. It really is only the one to nine keys and their corresponding shifted key. I have tried re-pairing the keyboard, setting the default keyboard settings, various keyboard on/off combinations, etc. Initially I thought my child hit some sort of keystroke combination that turned these keys off, but now I think it maybe more than this.Nothing has been spilled on the keyboard, and it has not been hit or dropped.
Unfortunately it sounds like a problem with the hardware inside the keyboard. Since it’s an entire row of keys, most likely a lead or two no longer has a connection to the keyboards main board. Since the keyboards are glued together repairing them is more or less impossible since it will be very hard to open them and then restore it to it’s original state.
