Pacjent to HP Omen 15-ek0026nw na płycie DA0G3EMBCD0 REV: D. Przyszedł do mnie ze zwarciem na układzie PCH SRJAU po wymianie na nowy od chińczyka laptopa wstał natomiast po instalacji sterowników karty geforce GTX1660Ti karta nie wstaje, pojawia się wykrzyknik w menedżerze urządzeń. Wszystkie napięcia na cewkach karty obecne. Co zrobiłem:

Reflow układu graficznego do roztopu kulek
Naprawa bios w programie UBT2 (FULL FIX, ME, MAIN, DMI)

Proszę o dalsze rady.
