Same thing on another power adapter. I observed something:
Turned on with only power adapter pluged or adapter with battery:
PQ2:
Pin1 0V
Pin2 5V
Pin3 0V
PQ3:
Pin1: 5V
Pin2: 0
Pin3: 0
Point 3 on resistor have: 3.3V, point 1,2,4 have 0V
Turned on with only battery:
PQ2:
Pin1 3.3V
Pin2 5V
Pin3 3.3V
PQ3:
Pin1: 5V
Pin2: 0.04V
Pin3: 0V
All points on resistors have 3.3V and plugging power adapter doesn't change measurements
