Witam.
Laptop jak w temacie.
płyta to: M1403QA Rev 2.0
KBC to IT5125E-128 CXA
Charger to BQ24800
CPU to RYZEN 7 100-000000098

Klient postanowił sobie sam go wyczyścić i wymienić pasty.
Pomijając, że na cpu past jest chyba nie wymieniona albo tak wyschła w ciągu dnia :D to cały tor zasilania cpu aż w niej pływa .
po tej operacji laptop się nie włączył.
Przynajmniej tyle mówi klient.

Objawy jakie mam na stole:
po podłączeniu zasilania laptop odpala na 10-15mA spada do 0 po chwili wstaje na 35mA i tyle cała reakcja.
3,3V obecne na cewkach 5V także
1,8V na pamieci bios także obecne.
Podstawiałem inny wsad biosa ale brak zmian.
Nie widzę nigdzie zwarć na cewkach zasilających oporności mierzone na CPU około 3 ohm.
grzał się jedynie dysk M2 w termowizji

Co mnie zastanawia to że laptop nie podejmuje w ogóle ładowania a wydaje mi się, że samo ładowanie powinno się uruchomić. Bateria podaje napiecie na PCB

Moje podejrzenie, że Klient coś zwarł bo pewnie nie odłączył aku przy tym pastowaniu.

Nie mogę namierzyć do tego żadnych info za nowe :D
Pomocy :D
