Trackpad and Keypad not working.
So Yesterday while using my MacBook Air all of a sudden my trackpad and keypad stop functioning. I restarted the system and it started searching for a bluetooth keyboard. I looked online and seemed like a common issue and the common solution was opening the laptop and look for lose cables or change the logic board however I feel this is not the right solution in my case.
I have a dual boot system since few months I've got MacOS & Ubuntu. The problem is only being seen when I log into MacOS. Once I start my system, I get the OS Boot up screen where I choose the OS. The arrow and enter keys work fine. I chose Ubuntu the trackpad and keyboard works fine. It's only when I chose MacOS the system can't detect any trackpad or keypad. I am using a USB keyboard & mouse currently to type this. I think these reasons are enough to conclude my logic board and all connections are good.
Does anyone have a solution for this? I also read some blog which said that MacOS disables some hardware to save any expensive damage due to heating issues. This could be one issue. Though I never had a heating problem. I just have office work which is minimal. But in case if it is, does anyone know if there is a way to disable this from terminal?
Or a hard reset for the system? I tried booting with PRAM reset holding P+R+cmd+shift. All the keys were detected and the boot took a long time then usual but it didn't help. I tried safe mode but still the trackpad and keypad was not working.
Please some help.. I don't have Apple warranty anymore.
