About 2 weeks ago, I spilled a small amount of juice on my MacBook Air (A1496) while it was on. I turned it off after whipping the keyboard off and turned it upside, letting it dry out for 2 days. When I tried to cut it back on, it came on fine and I could log in as usual. The only thing was when I got to the desktop, the keyboard and trackpad were totally unresponsive. I then connected an external keyboard and mouse to navigate through to see if there were other problems. The system ran slow. I then took it to Apple and they erased my hard drive and system reset my Mac but the keyboard and trackpad still weren’t responsive. They opened it up and said that there was liquid damage to my battery and needed to run a diagnostic for $700 (Basically for giving me a new motherboard) I then went home, opened up my system and cleaned it with alcohol letting it dry out for 4 days. I turned it on today learning that I did something right because my keyboard is back responsive. The only thing is that it still runs slow and the trackpad is unresponsive. Now I’m thinking that I should order a new battery and trackpad cable. Will that fix my problem?
You likely need to replace the trackpad and the cable may also need replacing to fix it. As to why your system is slow has to do with sensors on your logic board which is telling SMC your system is overheating, which of course it’s not. Lets see if its a temp sensor thats misbehaving.

Most likely, one of the juicy keys is stuck ON. Do you hear odd sounds as the keyboard buffer fills? Is the mouse erratic ? You must dis-connect the internal keyboard to test it. Was the touch-pad juiced ? Same answer applies , but there is bad news,,, most touch-pads are ‘capacitive’, when they wet, they die.
First try and run ASD and see if you have a specific sensor issue. First things to disconnect would be the webcam connector FIRST to see if the issues go away, and THEN try no battery. After that, if ASD doesn’t report issues, you very likely may have corrosion under the SMC on the board causing high fan speed and would require logic board repair. Check out the place in my bio for any help with that :)
Hi, Even I am having the same issue, and this was the most helpful post I could find online. Liquid was spilled on my MacBook Air A1466 (128GB SSD 8GB RAM). Liquid was all over the motherboard which I got cleaned (repaired) and my dead MacBook came to life. It is, but, now very very slow. I don’t know what to do now. Here’s a screenshot of TG Pro
Kindly help! Thanks in advance.
