Diagnosing SMC issue on liquid damaged A1932
Rather unfortunately, I have spilled some coffee over a A1932 Macbook Air.
Issues which I am currently experiencing are:
- the notebook will not work on battery, only with AC power plugged in
- I experience the behavior when fan is always working at max speed and the CPU is always throttled similar to Fan running at full speed, CPU throtled or Fans on max after new display fitted by Apple. And other issues
- apple diagnostics reports PPT006 (battery requires service) and PFM006 (SMC issue)
From what I gather, the full-on fan points to a possible issue with a temperature sensor somewhere. The most obvious guess is the battery, but in fact Mac Fan Control does report reasonable (?) battery temp sensor values:
Are all temperatures it reports.
So my question is how would I diagnose the SMC issue? Could it be caused by the battery alone (i.e. could replacing it be enough)? How would I go about checking if there are some malfunctioning temp sensors? Use some more powerful software? Maybe someone with this device could share there Mac Fan Control output.
Anyone with acess to a A1932 willing to help out?
Or perhaps output of
I wonder if the couple -128°C values are expected (i.e. sensors are not present in my model) or actually indicate the problem. Does anyone know what the Ts1S is? Or where the TB0T (Battery TS_MAX) could be physically located?
Questa è una buona domanda?
