Ciao ragazzi ho questo notebook Satellite Pro C50-H che non carica la batteria, ha funzionato fino a quando la batteria si è scaricata del tutto, analizzo il pc e vedo il mosfet in ingresso PQ4 bruciato, la sigla del mosfet è 8036 che non riesco a risalire al modello giusto del mosfet, ho sostituito il mosfet con altro modello, adesso il pc accende sia senza batteria e con batteria ma quando inserisco l'alimentatore per caricare la batteria l'alimentatore si spegne e va in protezione, forse il mosfet da me saldato è sbagliato, qualcuno sa indicarmi il modello di mosfet 8036?.

EDIT:
Sostituito con mosfet SM3319NSQGC-TRG, senza batteria funziona, con batteria collegata e appena inserisco alimentatore, va in protezione e brucia il mosfet PQ4.

Hello!
It's SSC8036GQ4.
Datasheet attached.

It's a suitable replacement.

Measure the voltages to ground on pins 1, 4, 5 of transistors PQ3, PQ4, PQ5 in the following cases:
a) Power supply connected only (without the battery).
b) Battery connected only (without the power supply).
