I have a 820-2850-A board, it gives a green light when connecting the charger but it does not turn on, they brought it without a battery installed, there is voltage in ppbus_g3h, q5315 gives 0v in ppbus_g3h vsense. Anyone know what can it be?

PM_SLP_S3_L_R should goes Hight if you would like to get ppbus_g3h vsense working .
Check PM_SLP_S3_L_R

You must be sur that you're in use for an original 85W Apple charger .

PM_SLP_S3_L_R debería ir alto si desea que ppbus_g3h vsense funcione.
Ver PM_SLP
I found that pp5v_s3 does not exist, apparently u7201 generates this signal but it does not give 5v, I have a doubt p5vs3_en is generated by this same IC or by the pch because this signal does not exist either
