22V into my USB port... How far does the damage go?
Yes, I am an idiot. I was programming a motor controller, and the VUSB pin shorted on the 22V lipoly battery, sending 22V back into my poor macbook pro through the right side USB port (next to the HDMI). It instantly shut off. It does not start up now, and the magsafe charger only shows a green LED.
Clearly I fried some or all of it. Would the computer start up without that right side IO board functioning? Is the SSD toast too? I’d love to salvage this computer if possible, but replacing the Logic Board is prohibitively expensive. I am an electrical engineer so I am comfortable reworking SMD components, are there any schematics/diagrams available? I guess my wishful thinking is that the damage was compartmentalized somewhere that I can fix it without needing to replace the entire logic board. Nothing on the circuit boards looks burnt or blue smoked…
Thank you in advance
