If I understand it correctly, the PIN_POWER_ON 46 is there to enable power to the board so it is necessary to pull it HIGH in the sketch. But if I want to power the device down I pull the pin LOW and it looks like only half of the board is withou power. After inspection of the schematic I have discovered the Q2 transistor is weird.

So my question is how to power down the T-embed when battery powered?
