Chosen Solution
Hello, guys. I’m so nervous… 2 years ago, 2017, I spilled ice coffee on the keyboard of my macbook pro retina 2015 early 13’. and then I cleaned and replaced keyboard and battery. it was solved.2018, summer, suddenly my keyboard didn’t work well. “Option key” seemed to be stucked, so I couldn’t input “English or Korean”. After all, I changed “keyboard and trackpad cable” only and then I could use keyboard well.However, recently, “option key” seemed to be stucked again!! even if I changed keyboard again!!!. I tried to use external keyboard, but it didn’t work well. I guess my trackpad or mother board has a problem. While I used laptop, sometimes my trackpad didn’t work zoom in or out. did you guys have same experience or have a solution? plz?
Your description makes me think some liquid might have reached the trackpad where it started some oxidation that built up over time. I’d definitely try a trackpad replacement as a first step before worrying about the logic board.
