Check U6900 & U6901, see that SMC_BC_ACOK is making its way to U6901 and that it is shooting this to U6900.

Check current sense resistors R7020, R7021, R7022, and the traces from them to U7000.

Check CHGR_ACIN pin of U7000 if SMC_BC_ACOK is not being shot out of U7000. If it has 4v on it and you are not getting SMC_BC_ACOK, replace U7000.
