Płyta DAAM9AMB8D0 rev D
laptop nie widzi akumulatora, był podmieniany na nowy oryginalny.
Wszystko działa normalnie, poza akumulatorem - nie ładuje, komunikacji brak
BIOS aktualizowany
Rezystancje na pinach złącza baterii na płycie:
1-3 -masa
4 -nc
5 -masa
6 -13,5kohm
7 -8,5kohm
8 -8,5kohm
9-11 - 1,5Mohm

co odpowiada za komunikację z baterią? charger czy kbc czy jeszcze coś innego?

Zmierz napięcia do masy na złączu baterii z podłączonym zasilaczem i baterią.

Odłącz zasilanie (baterię i zasilacz), odczekaj 1-2 minuty i zmierz rezystancję pomiędzy drenem (piny 5-8) a źródłem (piny 1-3) tranzystora PQ33, a także pomiędzy tymi samymi elektrodami tranzystora PQ40.

PQ33 - open line
PQ40 - zwarcie w tranzystorze :)

Wymiana tranzystora rozwiązała problem.
Bardzo dziękuję za konkretną i merytoryczną pomoc
