My MacBook boots up with the Apple logo just fine, but afterwards it just stays stuck on a white screen. I’ve tried booting into recovery as well but instead of a white screen, I get a blue screen, and it just stays there. I’m certain it’s not a hard drive issue because I used multiple hard drives and got the same results and the hard drives I used work fine on other computers. I’ve also tried booting into safe mode and resetting the VRAM and PRAM. I can’t reset the SMC because there is no battery in the machine at the moment. Other than the hard drives that I am testing, the only thing inside the computer is the RAM and logic board. Is this a GPU issue? Logic Board? How would I be able to fix this? Thanks!
Yes, you do have a dedicated GPU issue! But it’s not likely a bad GPU! Your symptoms imply the tantalum capacitor in the GPU power rail has failed. This is repairable! Review this Vid: MacBook Pro GPU Fault: C9560 FYI this is a 2011 not a 2010 as he states in the vid. Your test proves the CPU and the Intel graphics is working, nothing else here.
Hey I think I might have the exact same problem, when my computer first failed I took it into the Apple Store and thy said it was my hard drive. I replaced my hard drive with a ssd with no luck getting it started, I just replaced my hard drive cable and it boots up the same. I later tried plugging my old hard drive into a sata USB cable into a different computer just to see if the hard drive still worked and I could read and write files off of it so I am not completely sure that the drive is actually dead. Could you forward me to a guide that explains/shows what you did?
It would be a GPU issue. I would recommend checking out this link as it got my MBP working again. https://forums.macrumors.com/threads/for…
