Przetwornica 1.2V działa, ale chyba mam padnięty procesor i próbuję to zweryfikować. Wie ktoś może, jakie rezystancje powinny być na zasilaniach Ryzen 7 4700U? Ja mam:
CORE - 9,4Ω
VDDCR_SOC - 17,6Ω
+1.2VSUS - 2Ω (ta przetwornica zasila również DDR'y, ale podana oporność występuje przy pustych slotach).

Hello!
This resistance is definitely much too low, all other resistances seems in range of normal.

Open (cut) the jumper PR8713 and check on which side of this jumper you have a low resistance to ground. If the low resistance is present on the system side (power rail "+1.2VSUS"), inject 1.2V from the laboratory power supply to this pad and check which component on the board gets warm.
The APU processor is unfortunately very likely damaged.
