Keyboard and trackpad stopped working, it works only in login. Help?

I woke up my computer the other day finding the keyboard and trackpad not working. The only button working was the power button.

Try starting up in Safe Mode by holding down the Shift key on startup. This will disable any extensions that may have been inadvertently installed. If it does start up and run OK, you know it is a software issue. Also try starting up in repair mode by holding down the R key and run Disk Utilities.

All of these people and no answer i think i figured it out go to your system preferences. You will need to have a working mouse to get there obviously. Once your there go to Accessibility then click on the mouse and trackpad option. Once you are there you will most likely have ignore built in trackpad while using mouse. Uncheck that and your track pad should work now. You can disconnect your mouse and you should be good to go. At least thats what worked for me hope that helps.

"For anyone who may still be having this problem, I have just fixed the issue for a MacBook Air I am working on.

I tried all the PRAM resetting, deleting plist files, terminal commands, removing bluetooth devices and checking for viruses of which none of those methods worked.

I then turned to hardware as my issue, I removed the bottom cover and the battery then proceeded to remove the trackpad flex cable.

Once I had removed the flex cable I flipped it over to see the pins on the under side of the cable, I noticed on the motherboard side there was some black dust or debris or something on there so I cleaned that off with some isopropyl and a cotton tip and put it all back together and there you have it! It is all working for me now with no issues."

Creating a new user worked for me! I copied my desktop, documents, and downloads folder, created a new user, and pasted everything there :)
