Recently I've been experiencing unresponsive build-in keyboard and trackpad. The only key working is the power off/on.
I think the problem is related to Bluetooth module in the MacBook Air.
The Bluetooth symbol in the menu bar becomes crossed over with a sawtooth horizontal line and the keyboard and trackpad stops working.
No Bluetooth devices are paired or connected to the laptop.
External USB keyboard and mouse does not respond either.
I've deleted all Bluetooth preference files on the computer and rebooted the machine, nothing helps. There are no Bluetooth devices connected to the computer.
It doesn't help upgrading to OS X 10.8. I've tried and the problem is the same.
This is becoming so frustrating, what can I do about it?
