Re: Acer ZRW battery now charging

It wont work. Why you have not replaced those components?? Dont you see PQ22,pin4 is your ACDRV. Without the gate opening of this fet, charging will be disabled.Replace all those removed components first and then observe.

Re: Acer ZRW battery now charging

If there is no short circuit after PR213 and the BQ24780 chip is properly soldered, the operating voltages should be as in the diagram. PR5 resistance 20oHm is important.
