Hi, ;-)
i am trying to understand what is happening to this macbook retina 15 A1398 from 2015 year with logic 820-00138.
The macbook had a swollen battery, it seemed to explode, removed the battery the macbook has power, starts without errors but is very slow, very slow. From resource monitoring all cpu cores work very high even without applications started.
I tried another trackpad flat, I disconnected the webcam, I disconnected the wifi card, I tried another IO board, I tried with more SSD hard drives.
I did apple hardware test, no errors, checked all sensors and temperatures are ok, has no damaged components, carefully observed under microscope, could it be bad SMC?
I made the following measurements:
PPBUS_G3H 12,60v
PPVIN_S5_HS_COMPUTING_ISNS 12,60v
PPVIN_S5_HS_OTHER3V3_ISNS 12,60
PPVIN_S5_HS_OTHER5V_ISNS 12,60
PPDCIN_G3H 18
PPDCIN_G3H_ISOL 18
PP3V42_G3H 3,4
PPVRTC_G3H 3,3
PP5V_S5 5
PP5V_S4 5
PP5V_S3 5
PP5V_S0 5
PP3V3_S5 3,3
PP3V3_S4 3,3
PP3V3_SUS 3,3
PP3V3_S3 3,3
