Keyboard and trackpad not working even after changing the keyboard.
Liquid spilled on my MacBook Air 13" model: 1466.
My keyboard and trackpad stopped working.
I opened my mac and cleaned it all, and both are not working.
Trackpad is not detected and keyboard power button only is working.
I checked some fixes here (smc reset and RAM reset).
I could make smc reset with the keyboard (adaptor led blinked); and tried to make RAM reset but didn't succeed with the keyboard in this state.
Then I used an external keyboard and could reset it.
But I still have the same problem.
I noticed something when i used (show keyboard viewer) on screen keyboard: as you see in the attached picture, some buttons are pressed (even though I cleaned the keyboard very well).
So I decided to change the keyboard. I bought a new one and installed it and powered my mac and again I have the same problem: only power button is working and onscreen keyboard shows that the same buttons are pressed :( even though the keyboard is new and original.
Then I tried something else: I powered my mac and then carefully unplugged the cable which connects trackpad and keyboard to the logic board and restarted my mac with my external mouse. MacBook opened and of course not detecting keyboard or trackpad, but when I checked the onscreen keyboard, I found that still the same buttons are pressed :(
Now I turned it off and re-connected the cable.
Can somebody help me please? :(
