Chosen Solution
This MacBook Pro had been suggesting a battery replacement for a while now. A tiny water spill just took out the trackpad and keyboard, so it seems like a good time to swap out all three items. I assume that the suggested sequence would be battery, trackpad, then keyboard, but I’d appreciate any suggestions. The keyboard and trackpad themselves seem to be in good shape. Would you suggest trying to replace just the cables, or would it be better to replace the entire keyboard and trackpad?
If your sure you need all three then I would recommend you replace the full uppercase unit 15” MacBook Pro Top Case & US Keyboard, Apple P/N 661-02536 it will end up being cheaper and a lot less work! MacBook Pro 15" Retina Display Mid 2015 Upper Case Assembly Replacement
