I have a 2012 MacBook Air 11”. It had some wine spilled on it a while ago. I took everything out and gently cleaned it with isopropyl alcohol. It worked just fine, but the mouse wouldn't move.
Today, I took out the trackpad and gave it an ultrasonic bath in isopropyl alcohol. Now it won't turn on, except for on AC power (and even then only sometimes).
Is this related to the trackpad, or is it something different?

You’ll need a new trackpad as you ruined yours in the ultrasonic. These devices can’t be cleaned using a ultrasonic as the cleaning fluid (any) will seep into the plates damaging them.
Here’s the needed part: MacBook Air 11" (Mid 2011-Mid 2012) Trackpad
这个答案有帮助吗？
Thanks! Will this also solve the power issue?
First replace the trackpad to see where things are then.
Thanks! I replaced the trackpad and trackpad cable. This worked. Looks like something in the SMC reset circuit was messed up.
