Keyboard, trackpad and bluetooth went suddenly dead

this is very strange! Did your computer get any water damage of sort? The only possibliltiy I can think of is that something happened to the acctual parts inside of the computer than can be blocking the circut there for not allowing things to work. I would wait to see what other people would say, but if you are confirtable, I would open up the bottom of the computer (I dont know if mac airs can) and I would just lightly blow and make sure theres no dirt blocking anything. Its odd how restarting didn't do anything. On a mac air, can you remove the battery? If you can, remove it and leave it out or a minute or so. Also, if you will remove the back, make sure its fully off, unplugged, and dont touch anything thing in side. You dont want to short circut it. (That can also be a reason why) If nothing fixes it, just take it to the apple genus bar. They will be able to fix it some how.

try this. turn of the computer. Then hold down the control key. While holding it down, click the power button to turn it on. Wait up to 20 seconds while holding it down. Does a menu appear? If it doesnt work with the control key, try command. Im not sure, but i think its control. If it does pop up,let me know.

ok, so that rules out that lion is corrupted. The easy fix to that would be to restore lion from recovery. So nothing work once computer is on? You can even login then correct?

lion can still work fine and still be corrupted. Just some features can be corrupted. Something was corrupted on lion, which still worked normally, but re installing it fixed the issue.

The only thing I can think to do is just go to an apple store and make an appointment for the genus bar. Its free to diagnos, and might cost money depending on the warrenty etc... Hope I helped!

Hi Jaime

Did you find any solution to your problem? Because I'm in the same situation, randomly, my trackpad, my keyboard, the right usb and the bluetooth go dead. However, it sometimes works, and I've seen that in the hardware information of the macbook they are all conected to the same usb bus. Furthermore, in my case, when my macbook air is dead, if I shut it off (power button still works) I can't boot it again, it appears a grey screen, it sounds the starting sound, but it still sounds again and again and again... in that situation, the only thing I can do is waiting a few hours, then I can boot normaly, but in a few minutes, the situation starts again.

Thank you very much for your answer, it's what I feared... today, just after writing here, the keyboard, trackpad, etc. died, but I tried to push in the zone sourrounding the broken usb (just a little, I heard no cracks) and it suddenly became alive! so probably it's a probrem with some wire or something like that. I'll take it to an apple store, I hope mine is under warranty because it has 13 months, but I believe that here in Europe we have 2 years of warranty, we'll see.

Again, thank you!

Hi Alex,

Any luck on having Apple have this fixed.

I have the exact same issue as Jamie stated here.

Hi

I talked to Apple's SAT and like my MBA was working while we talked, they did nothing... so I hope it won't break anymore.
