Thank you for this! I identified and changed a diode in the power circuit thanks to this and the laptop works now!

Hi,
big thanks for your schematic Lisa Su. Due to your help i was able to identify most of issues with my laptop. But i have rev 1a and nearby charging port (alredy removed, burned) i have lost cap (PC210 or PC9207) and probably resistor or Thinking CPTC thermistor(PH301). Thtats my guess based on your files(cause in it, there is no cap betwen PH301 and +19Vin), maybe do you have rev 1a schematic or boardview or simply know answer?

I know that comment is from february, but for someone else, maybe is helping.
So, resistor that you circled in picture, is a 0 ohm resistor(like a fuse); my mainboard is working.
