Failed trackpad and keyboard
Working with a MacBook Air 13" Mid 2012. Trackpad and keyboard failure arose after minor water damage (water likely entered from ventilation holes as keyboard was covered with silicon protector): everything except the power button malfunctioned.
Replaced the upper case cable and the problem was resolved until a week later, when the same failure recurred.
Any diagnosis and recommended repairs welcomed. Thanks!
Is this a good question?
