Hi everyone.
This macbook does not work the keyboard illuminator, I see that in the system preferences it does not detect it.
I tried another plate of the same model 820-01521 in the case and if it is detected by the lighting in the system preferences and when I press the keys it lowers and raises the lighting without problem.
So I know it's a motherboard problem.
In the J6700 connector I made measurements of the Diode with the good board and I only have two altered values
"PDM_DMIC_DATA0_ISOL"
"PDM_DMIC_DATA1_ISOL"
I think this is from the microphone, I tried it and the microphone works.
PP5V_G3S_IPD_F : 5.1v
PP3V3_G3H_IPD_F: 3.3v
PP3V3_G3S_IPD_F: 3.3v
Am I forgetting something?
