have a rtx3090 with no power, can someone tell me if 1.4ohm on PS_NVVDD_DRVON is normal (pin31 on AOZ5311)?
i checked all the voltage rails and fuses and they seem okay 12v. but i am missing PS_5V_PGOOD
closest schematic i found is:
MS_v389
NVIDIA_GeForce_RTX_3090_600-1G132-0030-300_PG132-A02_Rev_C_

this is readings from U31
PS_5V_EN 2.5v
PS_5V_SW_VCC 5V
PS_5V_SW_BOOT 9.84v
PS_5V_PGOOD 0v
PS_5V_SW_PHASE 5v
12V_EXT8_F1_RTD3 12v

thank you

diode mode red to ground .378
200ohms red to ground no reading...

Hello. Have a macbook with motherboard 820-01987 that's not charging. Initially it came with a short and managed to trace it to PP0V9_TBT_X_SVR, I removed u2800 and short went away. I ordered JHL6540 replacement but now I get no charging it's stuck at 5V.

Thanks any help would be appreciated...
