Hello,
I am not getting battery detection on this logic board. Tested with a known good battery.
Checked resistance on R5280 and R5281. No corrosion around the SMC that I can tell. PP3V42_G3H is present.
SMBUS_BATT_SCL (SMBUS_SMC_5_G3_SCL) was shorted to ground, the SDA line was OK.
I replaced the ISL6258 U7000 and the short is gone, and diode mode measurements put it in line with another board that I had.
Any thoughts? Bad SMC?
Thanks,
Stefan
