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.

Measure the following voltages to ground with an oscilloscope:
- On pins 1, 3 of quartz YG1.
- On pins 1, 2, 3, 5, 6, 7 of VBIOS chip UG2 immediately after pressing to the power button (without the hard drive connected).
