Hi!
Recently my Macbook Pro started freezing and the screen would pop fuzzy red lines over what I am doing, a
few seconds later, it would shut down. At times it would even totally glitch out, scrambling my screen.
I did a diagnostics test and it showed an error code PPN001, saying I have issues with my power management system.
I also did some Googling, indicating this might be a GPU failure, but my model doesn't have a dedicated GPU.
I have no idea whats going on, can anybody shed some light?
