Płyta NM-B452 Rev: 1.0, na początku brak reakcji + brak ładowania. Po wymianie PQ316 laptop działa na zasilaczu jak i na baterii, lecz jej nie ładuje. Proszę o sugestię.

Bateria sprawdzona, naładowana w innym urządzeniu.

Hello!

Measure the resistances between listed pins of charger chip PU301:
- Between pin 25 and pin 26.
- Between pin 26 and pin 27.

To be able to recharge on the battery there must be 8.4v.
Maybe it's not recognized.
Start software https://www.elvikom.pl/hp-at1-napiecie-baterii-w-batterymon-0v-t12187.html and post a screen of "battery info", when the battery + Power Supply Are Connected.

Replace the transistor PQ317 regardless of whether, if it seems functional or not.

Measure the voltages to ground on pins 1, 2, 3, 4, 6, 19, 20, 28 of charger chip PU301 with power supply + battery connected.

Is this measurement correct?

If so, measure the resistance between pin 1 and pin 2 of charger chip PU301.

Yes, measure of 1 pin of PU301 is correct. resistance between 1 & 2 pin of PU301 over 5MΩ

One of the highlighted copper traces (picture below) is probably broken. Check them.
