The keyboard on my Macbook Pro (13”, Retina, Early 2015) will work for some time then stop working during use or when logging on after sleeping or booting up. The power button and trackpad work, but the length of time the rest of keyboard doesn’t respond is not consistent and can last multiple days at a time. I did spill something on it months ago, but the issue did not arise until a month or two after that incident. Is there something that needs to be replaced internally, or does the keyboard need to be thoroughly cleaned?
Water damage can take quite a bit of time to start making an impact towards a device, sometimes it could take only a few seconds while other times the liquid could take months to make an impact. I would guess there is a component on the logic board which is getting hot after a bit of use, or there is some corrosion that needs to be cleaned. Cleaning the board is certainly important with water damage to make sure that it does not get worse, as corrosion is not good for any device. There may be some corrosion which is causing this, however without opening up the device it can be harder to judge. Hope this helps!
