Question

Macbook pro Late 2011 13.3 inch i7 keyboard and trackpad not working bluetooth showing a cross sign and no usb mouse is detected. Almost dead keyboard and mouse. Earlier same problem used to be solved by opening the lower cover and closing it.

My macbook pro 13.3 inch i7 late 2011 edition has previously encountered unresponsive trackpad and keyboard. To solve that, I used to open the back cover and then close it. It has been working fine since that. Yesterday, same thing happened, this time I noticed that bluetooth icon is showing a cross sign across it and keyboard and trackpad were unesponsive. After some time , everything worked fine and bluetooth sign was back to normal. Then , suddenly it went back to the problem. I shut it down by holding the power button. When I booted it again, I could not login because keyboard and trackpad were not working. I attached a HP mouse it didnt work. I opened the back cover disconnected the battery and then connected it again, didnt worked. Since then , I have tried many things and nothing has solved the problem.

MacBook Pro, OS X Mountain Lion (10.8.2)

As you suggested I have reset the smc. While resetting procedure the power led changed status. Does that mean that my keyboard is OK?

But after starting the macbook pro , neither trackpad nor keyboard worked.

This system may still be in warranty, depending on when you bought it, and you would be foolish to Fool with it anymore then you already have. It has a Hardware Problem and is covered by the warranty. Take it to an Apple store and have it Fixed.

As Shootist007 suggests, take it in to the Apple store, disgnosis is free, and if you are still under warranty or AppleCare, let them deal with it.

As you suggested I reset the smc, in the first boot nothing worked. In the second boot, it all worked like a charm. I thought that my problem is resolved now. To test it, I shut it down properly. Next morning, I powered it on, all things i.e, keyboard, trackpad, bluetooth etc. worked and I thought that problem has been solved. When I was just going to visit apple forum to reply you, the same problem reappeared. A sawtooth cross over bluetooth icon, keyboard not working, trackpad not working,no usb mouse working which worked well when it was fine. I reset smc so many times again and again but same problem continued. Isn't it a problem of the firmware?

Next time when it will work, I will update its firmware.

My macbook was bought in dec2011 so no warranty now.
