Chosen Solution
My MacBook Pro late 2013 suddenly became slow and fun running at full speed, due to the region I’m in there is no autorized apple support store, went to a apple reseller and they told me that the battery is causing the problem due to old age and 1030 more cycles. I have TP showing that the battery is actually at good condition but GPU temperature senseor might not be working properly and coconut battery app showing the battery in good condition. Used the apple diagnostic and got PFM006 and there many be an issue with the power management system ref code PPN001, which I can’t find any of this ref code. PPN001 not typo see photo.
Any ideas, please
This error is often related to liquid damage (corrosion around the battery connector). Did you have a spill or sit the system down on a wet surface? It’s also possible the area where you live is very humid which can also cause issues.
Same problem happend to my MBP 11,1. The battery pack is OK. Tried with refit and SmcFasher.efi -reset 1 to reset my SMC, because Shift-Ctrl-Alt didnt work. SMC reset via refit has no effect. Think, that my Logic board is broken
