Hi, everyone.
I have this notebook that won't charge.
In Windows, the charger icon doesn't appear on the battery, but the charger turns on the notebook normally.
PU301:
Pin 5 (ACOK) - 5.97v
Pin 6 (ACDET) - 1.83v (should have 2.6)
Pin 16 (REGN) - 6v
PQ308 has no gate voltage, so it doesn't drive PQ309 low
With the battery connected, its voltage goes the reverse way to the jack, having 14v and not 20v:
PQ301 e PQ302
Pinos 1,2,3 14v
Pino 4 5v
Pinos 5,6,7,8 com 14v...
