PLEASE, do NOT write all in capitals.
Do you really read more easy letters with the same height in a row???

Does the board starts on charger alone with 0V at PM_BATLOW_L?
That is very strange.

SMC_RESET_L is lower than normal, but SMC can still recognize it.
However, I would like to get normal value there.
Start reballing SMC...
