Hello! Need help in solving issues with my aw 17 r5. I have curently a gpu error code. And black screen. All voltages are on motherboard all resistances are fine and I’m suspecting the nvidia gpu as according to the schematic laptop outputs image to the EDP DP and HDMI from nvidia but it also can output image to the thunderbolt port but from the intel gpu. I need anyhow to get image not from nvidia card to run diagnostic software such as mats and check what is causing an issue with nvidia error code. But the firmware is designed that way to hold laptop from boot or pass that error. It reacts to num lock or caps lock key on keyboard but blinks an error code. So I want to ask someone is it possible mod bios that way to force intel gpu output an image to external monitor during boot and not check nvidia for errors to let me run software?
I upload an image that shows output diagram of this platform and bios dump.
