[FONT=Calibri]Hello,[/FONT]
[FONT=Calibri]I am currently working on a Macbook Pro [B]A1990 [/B](motherboard [B]820-01041[/B]) which is not charging.[/FONT]
[FONT=Calibri]The Macbook consumes 5V and 0.019A at USB-C. There seems to be a partial [B]short-circuit[/B] on the [B]PPBUS_G3H [/B]rail as I have 0V on this rail.[/FONT]

[FONT=Calibri]I've physically separated (by removing F7000 and F7001) PPBUS_G3H and the ISL9240 charging chip to see which side the short is coming from. Removing these fuses gives me 12.6V at the output of the ISL chip (PPVBAT_G3H_CHGR_REG).[/FONT]...
