Used MacBook Air Retina 13-inch 2019. Machine will still power on and chime when plugged in from wall, can't say the same when its not plugged. Wont boot past the final OS Install phase. Keyboard will not light up or respond, it used to work but now it does not anymore. There was a slight liquid spill but the machine was still working perfectly after I cleaned it up, but now its all downhill. Screen is in perfect condition, trackpad is damaged and no longer working, and i'm not sure if that even able to be fixed. USB-C/Thunderbolt Port work just fine without issues.
