Sorry, I did not see it got merged in the first place. Thank you for that.
Now, I flashed the bios of lapfix and the lock still remains. Also, I read the link for the bios unlocks but I could not find for my case, the 1F5A. Unless I understand wrong.......Leave a comment:

Asus ROG Zephyrus G14 GA401IU-HE103T GPU Nvidia Issue
Hello all,
I am having an issue with this laptop, on which I repaired the motherboard on other power issues (PMIC, mosfets etc) and it came back to life, but I am having problem with the GPU NVIDIA GTX 1660. It gets error 43 in device manager with exclamation mark and does not work. When I install official asus driver or official nvidia latest, the error goes away until you reboot the laptop, where the error comes back again.
GPU-Z software does not show many information and vbios info is missing (photo attached).
Because the customer sent the laptop to 2 other labs trying... -

HP Omen 17-W202NV Error 90D
Hello.
I am facing an issue with this laptop HP Omen 17-W202NV with motherboard: DAG37DMBAD0 REV D G37D 915467-601 which has a weird symptom.
It turns on and shows at post, error 90D (overheating issue). It starts immediately fans at full speed. Then once it goes to login screen, it shows the logo for half second and it shuts off, and in the next boot it shows again 90D error.
If you stay in the BIOS menu it does not turn off. I also managed only 1 time to boot into Strelec WinPE temporary system to diagnose and it did not show the NVIDIA gpu in the HWInfo. Looks like... -
Let me note that the coil PL509 is 0.19v when PJP505 is connected, when disconnected 0.9-1.0v like I said in the first post, and PL508 +VCCSA is 1.1V.Leave a comment:

Unfortunately on the cpu side is 0ohm, measured with digital and analog multimeter. Also, I tried to voltage inject 1v with 5A limit on this coil and it gives out 1v 2.5A. The voltage does not drop. With this injection, CPU does not get hot. Is there any chance it is something else you believe?Leave a comment:
