Hello friends.
A 15 INCH MBP with the motherboard 820-3330-a this case, came totally dead.
No chime, only fan spinning, so I tried to reset the NVRAM, then I had a chime, but no image.
Ive been measuring the coils and GFX power rails and found them to be =0v
Im thinking this might be a VGA issue, and since I did a NVRAM reset the computer removed it from the checklist, now I need a proper BIOS to enable the Integrated GFX Card, anyone here has such BIN?
Or could help me with the parameters I need to modify in my extracted bin.
Thanks a lot for any help provided, and sorry for such a long message.0
