My 5 year old spilled a glass of water on the keyboard and after opening and putting the computer upside down for a couple of days, it would not do anything. After sitting dead for a month I decided to crack it open. I found a bunch of corrosion (no surprise) on the logic board and some of the connectors and cleaned it all with alcohol. When I put everything back together, the computer actually began charging and was awakened from its sleeping state. However, the keyboard was not working properly, so I decided to order this upper case. While tedious, the replacement was not too difficult. When I finished and powered on, it started up no problem, but it would not connect to the internet (wifi connected, just no internet). A simple restart fixed this issue. Now, the only issue I’m dealing with is that the left “shift,” “opt/alt,” and '“ctrl” keys do not work. The standard advice is to reset the SMC, but this requires the use of the affected keys. Please help!
