Re: Help understanding ACDET voltage divider A315-23
This sounds right.
I was only thinking one dimensional just chasing the 19VDC, and forgetting about the battery aspect. Got too fixated.
AC Adapter gets plugged in, removing PQ9 bias, therefor allowing PQ3 and PQ4 for the 19VDC to continue it's path.
If I got that correct... (sorry been 17 years since I took my electronics training)...

Help understanding ACDET voltage divider A315-23
Greetings.
Aspire A315-23 board (da0z8emb8c0 Rev c), no power.
19VDC is at PQ3 pin 5. Nothing coming out, and started working around the power circuit.
The ADP_ID pin (3) was pushed all the way inside the DJ jack (new one on order), causing it to not make contact with the barrel connector on the AC Adapter (nothing new), and where it wasn't my laptop I didn't just want to jump it to the DC Jack ground and call it a day.
I can see the voltage divider circuit from PR71 and PR69 to PQ9. But some reason I cannot remember how if the DC...
