MacBook Air keyboard problems
Hi,
I've got a mid-2013 MBA with 1.7Ghz i7 processor. I tried using an Apple bluetooth keyboard with the MBA connected to a TV. This worked fine, but when I went back to using the MBA's native keyboard, there were functions that disappeared, for instance, the display brightness keys and the keyboard backlight keys no longer work. Only the ESC key still works amongst the top row of function keys. How do I correct this problem? Thanks in advance,
Nick
