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 ja k will provide a ground to the ADP_ID line in between PR71 and PR69, how PQ9 will work with now essentially the DC jack ground now sitting at PQ9, pin 2.
My question is:
Can someone walk me through the circuit path as to how the ADP_ID line will allow the ACDET to work, thus allowing the ACDRV to bias the MOSFETs.
Thanks in advance.
