Hello,
i've been working on macbook air 820-01521
it is dead no charging. tried to connect to apple configurator always shows accessories not supported.
using amp meter only shows 5V and 0.04A
here are some measurements:
PPBUS_G3H = 12.26V
PP3V3_G3H = 3.275V
PP5V_G3S = 0V
PP20V_USBC_XA_VBUS = 5V (can i inject 20V 1A here?)
