    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?

    My MBP's keyboard and trackpad has suddenly started to stop responding too, I think the issue is related to USB devices, since when its happened twice, both times I have had my USB drive plugged in. Has anyone else had this problem?

    Yeah, there is another recent thread about it happening when USB devices are plugged in. The OP in that thread said it was resolved with an SMC/PRAM reset.

    It happens to my Air when I plug in my external hard drive. Gonna reset mine later today when I have a chance.

    The issue was not related to USB devices plugged into the laptop.

    After af force power shutdown (holding the powerbutton down for several seconds) the laptop is now caught in a boot-loop.

    There's no response from the keyboard so it is not possible for me to do a safe restart (Shift-Power) neither a SMC reset (Shift-Control-Option-Power) or a PRAM reset (Command-Option-P-R)

    Now I'm stuck with a laptop in boot-loop all due to a new Apple operating system :mad:

    Try a USB keyboard, perhaps?

    While the laptop is in the boot-loop I've connected external Apple white USB keyboard. The laptops does not respond to the keyboard as I pressed the different key-combinations.

    Go to the Apple store and let them deal with it.

    Most other choice require you to be able to hold down various keys on boot. With no keyboard that isn't an option.

    A swelling battery has caused all types of keyboard/trackpad malfunctions for me in the past.

    Just something to consider.

    Hi, I'm facing the exact same problem with my MacBook Air mid-2011 where my trackpad and keyboard dies and bluetooth has the buzzsaw symbol over it.

    Anyone figured out what the problem was?

    Thanks guys.

    I'm getting the same thing sometimes.
    Other times after boot it will just ring the chime every 5 seconds until its powered off.
    This current time (I'm typing this on the wife's computer) the bluetooth mouse worked but then I couldn't type my password as the built in keyboard isn't responding.
    No USB devices are plugged in.
    I've plugged in an external Apple keyboard, but then noticed that the mouse has stopped responding. Time for a reboot!
    External mouse left port works. External mouse right port does not. External mouse in the USB on the keyboard works!
    Might try a reboot with PRAM reset alt option P R
    Which hasn't fixed the keyboard...

    I experienced this same problem after upgrading to El Capitan 10.11.3. Got it solved by booting in safe mode (holding shift key while booting), and resetting the disk permissions.
    I referred to this link to resolve the boot loop problem-

    to reset disk permissions -
