Hello , I have a problem with SMBUS_SMC_BSA_SDA have short to ground with magsafe connected.....
The macboook pro boot to OSX , but no detect battery.(battery is new).
I have low voltage (with magsafe only) on Pin 2 of R5280=0,60V to 0V, I decide to desoldering R5280.
R5280 & R5281 are Ok
(probably ,because on pdf '' K18_820-2850 A1286'' , R5280 & R5281 display 1 KΩ but they have 2KΩ on board (after desoldering) ).
So SMBUS_SMC_BSA_SCL is OK.
SMBUS_SMC_BSA_SDA without magsafe:
SMBUS_SMC_BSA_SDA with magsafe:
U7000 / ISL 6259!!! replace by new.---------
