Arrived with liquid damage. Replaced U4801 but still no trackpad or keyboard. Using known good keyboard and trackpad. Power button on keyboard works. Boots into OSX no problem.
Replaced U4801. diode mode on all pins of J4800 and J4813 is good. PP3V3_S4 is present. R4800 and R4808 are good as well.
what to check next?
