Acer Nitro 5 AN515-55-53M3 (FH52M LA-J891P Rev: 1B) GPU memory rail
Hello, i have Acer Nitro 5 AN515-55-53M3 (FH52M LA-J891P Rev: 1B), on GPU (nVidia RTX 2060) memory rail have ~0.5 Ohms resistance is it normal? or dead GPU?
Prehistory: There was short on main rail, ~0,1 Ohms. Problem was double mosfet AOE6930 who is feeding GPU memory rail, i changed it and short is gone, and laptop turns on, but discrete gpu wont' work, video drivers install was succesfull. Some
insights? -
There is no voltage on vcore rail. cpu is cold as ice. I meassured PPVCCSA_S0_CPU more accuratley there is 0.2-0.3 ohm reading...

I've found very low resistance to ground, it is ~0.7-0.8 Ohm on L7330 inductor. This is PPVCCSA_S0_CPU rail. Is that resistance is normal or cpu is dead?Leave a comment:

Without trackpad the fan spinning super fast, like turbine. Shorting pads of DEV-POWER BUTTON do nothing.Leave a comment:

It powers on, fan spins non stops, cpu not hot.
PPBUS_G3H = 12V.
ALL_SYS_PWRGD = 3.3V.
Maybe bios is coruppted?Leave a comment:

Those two inductors show ~50 Ohms. Is it normal?Leave a comment:

Hello,
i've got the same mac. Want t know, maybe someone knows what normal resistance are on L7960 and L8000 phase inductors?
Thanks in advance. 🙏Leave a comment:
