Hp 17-ab burned IC vRAM and dead vga chipset

[quic307]

Hello team,

I have one HP 17-AB with motherboard DAG37DMBAD0 REV D. The motherboard has problem with burned IC vRAM and dead vga chipset.
When I opened it, I get 5-4 blinging error and after 3 times opens and works.
I want to use the notebook with cpu only and to deactive the vga.

Does anyone knows how to by pass the error?

I attached schem and photos.

Remove R79 and add R78(100K)

If that works, then you can remove coils for graphics power.

Hi friend,
I made the r78 install (100K) and r79 uninstall, I removed the coils PL9017, PL9018, PL9019, PL9020, PL9010.

I made Bios clean reprogramming. Same isswe !!!

What else? To remove all chipsets U10, VRAM1001, VRAM1000, VRAM1003, VRAM1002, PU9009?

Or to find bios for UMA programmable...

Thank you in advance....
