Keyboard and trackpad stopped working - Macbook Pro, mid 2014

Hi,

I have a macbook pro, 13 inch retina display, mid 2014 edition. I face the same problem like the late 2013 matchbook pro version. After a while, the keyboard and trackpad stopes responding. This usually happens when the machine goes to sleep. I have to restart the machine by pressing the power button for more than 5 seconds. Nor the keyboard, neither the trackpad responds for more than 30 minutes. After several restarting the machine, both keyboard and trackpad begins to work.

I tried to download the EFI solution produced for the late 2013 version of macbook pro. But as you can imagine, I was not able to install the patch, because my machine is a mid 2014 product.

I need urgent help, I can't work with this machine and don't know what to do.

Thanks...
