My power button, keyboard, and trackpad stopped working!
this happened after i replaced magsafe plug, at first some of the keyboard buttons stopped responding, then i opened the laptop again and tried moving the flex cable of the keyboard, the problem remained but other buttons stopped working, then all of the keyboard, power button and trackpad stopped working, i could turn on the laptop without the power button by removing the battery and connecting the charger, it showed that there were no keyboard or trackpad connected. please help me solve this problem.
Is this a good question?
