Is the SMC or PMU a separate daughter card on this model (A1297, 17 inch early 2011 macbook pro)? Can it be “bad?”
derrick, according to your specs your logicboard should be 820-2914. The SMC is part of the logic board. It is reference designator U4900 and is a Renesas DF2117RVPLP20HV. Hope this helps, good luck.
You have “referenced 5 different models of machines”. Yes SMC chips can go bad. If this answer is acceptable please remember to return and mark it accepted.
If you think the fault is the SMC chip, you can try to re-flow first and see if that would work. Put 2-3 drops of Kester 186 between logic board and SMC chip. Pre-heat the board to 110-120C and gradually heat the SMC chip to 245C. Use thermocouple on top of chip to measure the temp. Put a desktop computer screw on top of thermocouple to avoid being hit directly by the heat. If you have a digital USB microscope you can watch when the solder balls will melt
