Liquid damaged macbook Air

Wine spill on keyboard

no major areas of damage that I can tell, Most damage I can see was 2 slightly blackened pins on the keyboard connector and some dried wine spots on the board.

Board has only been scrubbed in the small spots where wine was dried. Has not been through UC.

All main rails are there but CPU power is not turning on.

Not too familiar with the power sequence for CPU VCC.

Computer boots now. No backlight but I think its just the diode on the boost circuit is bad.

Thank you guys so much. I now know how the circuit works a little more.
