Spilled coffee on my mac, brought my mac to the store and it came out fine. Used it for more than a year and out of nowhere trackpad and keyboard working intermittently.
Same issue and they only replaced IPD FLEX CABLE. Funny because Apple store in the Philippinrs said that they also have to change battery and topcase but when diagnosed here in China, they only said the IPD FLEX CABLE is the only thing they changed. They saved me money but not 100% sure if the problem pops up again. Still have to retrieve my MacBook pro 2015 retina, this week.
