    HP GALE 4G WHL MB- 18709-2 x360 Envy Charger

    Owner replaced the battery, but plugged in with backwards polarity. From AC works great, akku seems to be dead. I replaced the battery, powered on from battery, works for some minutes, then boom, shooted off. The another (used) battery seems to be dead too. Charging voltage 3-4V, Before PQ4403 10V. Shottky and the caps measured ok. After a while of "charging" led flashing white. Could be only the batteries?

    Can you link a schematic if available? Link it only if inside the schematic forum - not here.
