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 to repair it, I don't know what they did exactly. I noticed that the bios chip was soldered and a connector next to it a bit melted from hot air, BIOS is also missing the serial number of the laptop, so something there is not nice. Also, usb mouse+trackpad do not work inside bios. FYI, BIOS shows the nvidia card.
GPU power rails and vram rails are all up and running.
Do you think that this could be software/bios/vbios related issue?
Attached you can find the bios and vbios chip dumps.
The board is GA401IV REV1.4.
Laptop Serial Number L7NRKD00345129B
BIOS latest 222
AMD RYZEN 7 with GTX 1660
CN: B60H
MFD: 2020-07
Thank you in advance.
